Influenced by the view of some twentieth-century feminists that women's position within the family is one of the central factors determining women's social position, some historians have underestimated the significance of the woman suffrage movement. These historians contend that nineteenth-century suffragism was less radical and, hence, less important than, for example, the moral reform movement or domestic feminism—two nineteenth-century movements in which women struggled for more power and autonomy within the family. True, by emphasizing these struggles, such historians have broadened the conventional view of nineteenth-century feminism, but they do a historical disservice to suffragism. Nineteenth-century feminists and anti-feminist alike perceived the suffragists' demand for enfranchisement as the most radical element in women's protest, in part because suffragists were demanding power that was not based on the institution of the family, women's traditional sphere. When evaluating nineteenth-century feminism as a social force, contemporary historians should consider the perceptions of actual participants in the historical events.

Which of the following statements would best serve as an introduction to the passage?
The author calls the predicament faced by the Historic American Engineering Record "paradoxical" (lines 36-37) most probably because
View Solution
Step 1: Understanding the Concept:
This question asks us to explain the meaning of the word "paradoxical" in the context of the passage. A paradox is a situation that seems contradictory but is nevertheless true. We need to identify the contradiction described in lines 36-43.
Step 2: Detailed Explanation:
The situation is that the "Historic American Engineering Record" needed special drawings to document the history of American engineering. One would logically expect that engineering students would be the ideal candidates for this job. However, the passage states that "the only college students with the requisite abilities were not engineering students, but rather students attending architectural schools."
The paradox is the contradiction: the students of a particular field (engineering) were not equipped to document the history of that very same field, while students from another field (architecture) were.
Option (E) captures this contradiction perfectly: "engineering students were not trained to make the type of drawings needed to record the development of their own discipline."
Let's analyze the other options:
(A) The paradox is not about the staff, but about the contrast between students of different disciplines.
(B) This is irrelevant to the specific contradiction the author points out.
(C) The comparison in the text is between engineering students and architectural students, not students vs. practicing engineers.
(D) The passage does not state that the drawings were complicated, only that they required certain "abilities."
Step 3: Final Answer:
The paradoxical situation is that the very people studying engineering were not the ones qualified to visually document it, a task that fell to students of architecture. Option (E) is the most accurate description of this irony.
Quick Tip: To understand a paradox, identify the two conflicting ideas. Here, idea 1 is "It's an engineering project." Idea 2 is "Engineering students can't do it." The paradox lies in the conflict between these two truths.
According to the passage, random failures in automatic control systems are "not merely trivial aberrations" (line 53) because

For which two uses of electricity was the ratio of the amounts of electricity used most nearly 3 to 1?
View Solution
Step 1: Understanding the Concept:
This question asks us to find a pair of electricity uses from the pie chart whose consumption percentages have a ratio of approximately 3 to 1. We will test the ratio for each pair given in the options.
Step 2: Key Formula or Approach:
\[ Ratio = \frac{Percentage of first use}{Percentage of second use} \]
We need this ratio to be close to 3.
Step 3: Detailed Explanation:
From the pie chart, the percentages are:
Air Conditioner: 53%
Water Heater: 20%
Large Appliances: 18%
Lights/Small Appliances: 9%
Now, let's test the ratio for each option:
(A) Water heater to lights/small appliances: \(\frac{20}{9} \approx 2.22\). Not close to 3.
(B) Large appliances to lights/small appliances: \(\frac{18}{9} = 2\). The ratio is exactly 2 to 1. Not 3 to 1.
(C) Air conditioner to water heater: \(\frac{53}{20} = 2.65\). This is somewhat close, but let's check other options.
(D) Air conditioner to lights/small appliances: \(\frac{53}{9} \approx 5.89\). Not close to 3.
(E) Air conditioner to large appliances: \(\frac{53}{18} \approx 2.94\). This value is the closest to 3.
Step 4: Final Answer:
The ratio for air conditioner and large appliances (2.94 to 1) is the most nearly 3 to 1.
Quick Tip: When a question says "most nearly," it implies you should calculate the value for all options and then choose the one that is arithmetically closest to the target number.
The electricity used by the water heater was measured separately and its cost per kilowatt-hour was one-half the cost per kilowatt-hour of the rest of the electricity used. The cost of the electricity used by the water heater was most nearly what fraction of the total cost of all the electricity used?
View Solution
Step 1: Understanding the Concept:
This is a weighted average cost problem. The cost per unit (kWh) is different for the water heater than for the other appliances. We need to calculate the total cost by considering these different rates and then find what fraction of that total cost is attributable to the water heater.
Step 2: Detailed Explanation:
1. Define variables for the cost rates.
Let \(C\) be the cost per kWh for the "rest of the electricity".
Then the cost per kWh for the water heater is \(\frac{C}{2}\).
2. Calculate the amount of electricity used for each category.
Water heater usage = 20% of total usage = 0.20 \(\times\) Total.
Rest of the usage = (53% + 18% + 9%) of total usage = 80% of total usage = 0.80 \(\times\) Total.
(Note: We don't need the 800 kWh value, as it will cancel out. We can work with percentages.)
3. Calculate the cost for each category in terms of C and Total Usage.
Cost of water heater = (Water heater usage) \(\times\) (Cost rate for water heater)
\[ = (0.20 \times Total) \times \left(\frac{C}{2}\right) = 0.10 \times Total \times C \]
Cost of the rest = (Rest of usage) \(\times\) (Cost rate for the rest)
\[ = (0.80 \times Total) \times C = 0.80 \times Total \times C \]
4. Calculate the total cost.
Total Cost = Cost of water heater + Cost of the rest
\[ = (0.10 \times Total \times C) + (0.80 \times Total \times C) = 0.90 \times Total \times C \]
5. Find the required fraction.
Fraction = \(\frac{Cost of water heater}{Total Cost}\)
\[ = \frac{0.10 \times Total \times C}{0.90 \times Total \times C} = \frac{0.10}{0.90} = \frac{1}{9} \]
Step 3: Final Answer:
The cost of the electricity used by the water heater was \(\frac{1}{9}\) of the total cost.
Quick Tip: In problems involving fractions or percentages of a total, you often don't need the actual total value. You can work with the percentages or fractions directly, as the total value will cancel out in the final ratio.
In November the Smythe household used the same total amount of electricity as in July, but the water heater used 33 percent of this total amount. By approximately what percent did the amount of electricity used by the water heater increase from July to November?
View Solution
Step 1: Understanding the Concept:
This is another percent increase problem. We need to calculate the amount of electricity (in kWh) used by the water heater in July and in November, and then find the percent increase from the July amount to the November amount.
Step 2: Key Formula or Approach:
\[ Percent Increase = \left( \frac{November Usage - July Usage}{July Usage} \right) \times 100% \]
Step 3: Detailed Explanation:
1. Calculate July water heater usage.
Total electricity in July = 800 kWh.
Water heater usage in July = 20% of 800 kWh = \(0.20 \times 800 = 160\) kWh.
2. Calculate November water heater usage.
Total electricity in November = 800 kWh (same as July).
Water heater usage in November = 33% of 800 kWh = \(0.33 \times 800 = 264\) kWh.
3. Apply the percent increase formula.
July Usage (Original Value) = 160 kWh.
November Usage (New Value) = 264 kWh.
Increase = 264 - 160 = 104 kWh.
\[ Percent Increase = \left( \frac{104}{160} \right) \times 100% \]
Simplify the fraction: \(\frac{104}{160} = \frac{52}{80} = \frac{26}{40} = \frac{13}{20}\).
\[ Percent Increase = \frac{13}{20} \times 100% = 0.65 \times 100% = 65% \]
Step 4: Final Answer:
The amount of electricity used by the water heater increased by 65% from July to November.
Quick Tip: You can also solve this problem just using the percentages, since the base (total electricity) is the same for both months. The increase is from 20% to 33%. The percent increase is \(((33-20)/20) \times 100 = (13/20) \times 100 = 65%\).

View Solution
Step 1: Understanding the Concept:
This is a detail question asking about a specific point made in the first paragraph. We need to find what the "defenders of photography" in the 19th century asserted.
Step 2: Detailed Explanation:
The first paragraph describes the 19th-century debate. It states, "Against the charge that photography was a soulless, mechanical copying of reality, photographers asserted that it was instead a privileged way of seeing...and no less worthy an art than painting." (lines 8-11).
This phrase directly states their main argument: that photography was an art form that was just as valuable and worthy as painting.
Let's evaluate the options based on this text:
(A) This is a use of photography, but not the specific argument mentioned in the passage.
(B) While true, their defense focused on its artistic merit, not its technological aspect.
(C) "Impartially observing" is a claim made by contemporary photographers (line 15), not the 19th-century defenders.
(D) This is a direct paraphrase of "no less worthy an art than painting."
(E) The passage does not state that they claimed photography would replace other arts.
Step 3: Final Answer:
The passage explicitly states that 19th-century defenders argued photography was "no less worthy an art than painting."
Quick Tip: For "according to the author" questions, the answer is almost always directly stated in the text. Scan the relevant section of the passage for keywords from the question to locate the exact sentence that provides the answer.

What is the ratio of the amount budgeted annually for food to the amount budgeted annually for savings?
View Solution
Step 1: Understanding the Concept:
The question asks for the ratio of the amounts budgeted for two different categories. Since the amounts are percentages of the same total budget, the ratio of the amounts will be the same as the ratio of their percentages.
Step 2: Detailed Explanation:
1. Find the percentages from the table.
Percent budgeted for Food = 20%.
Percent budgeted for Savings = 15%.
2. Form the ratio of the percentages.
Ratio of Food to Savings = 20 : 15.
3. Simplify the ratio.
To simplify the ratio, we find the greatest common divisor (GCD) of 20 and 15. The GCD is 5.
Divide both parts of the ratio by 5:
\[ \frac{20}{5} : \frac{15}{5} \]
\[ 4 : 3 \]
The simplified ratio is 4 to 3.
Step 3: Final Answer:
The ratio of the amount budgeted for food to the amount budgeted for savings is 4 to 3.
Quick Tip: When finding the ratio of two parts of the same whole, you don't need to calculate the actual values. The ratio of the percentages (or fractions) is sufficient and saves calculation time.
If a pie graph (such as the one above) were drawn to scale to represent the budget distribution into the five categories, what would be the measure of the central angle of the sector representing savings?
View Solution
Step 1: Understanding the Concept:
A pie chart represents a whole (100%) as a full circle (360°). To find the central angle for a specific category, we need to calculate that category's percentage of the total 360 degrees.
Step 2: Key Formula or Approach:
\[ Central Angle = (Percentage for Category) \times 360^\circ \]
Step 3: Detailed Explanation:
1. Find the percentage for Savings from the table.
The percentage for Savings is 15%.
2. Calculate the central angle.
We need to find 15% of 360°.
First, convert the percentage to a decimal: 15% = 0.15.
Now, multiply by 360°:
\[ Angle = 0.15 \times 360^\circ \]
We can break this down for easier mental calculation:
10% of 360° is 36°.
5% of 360° is half of 10%, which is 18°.
So, 15% of 360° = 36° + 18° = 54°.
Alternatively, using multiplication:
\[ 0.15 \times 360 = 54 \]
Step 4: Final Answer:
The measure of the central angle for the savings sector would be 54°.
Quick Tip: For pie chart calculations, it's useful to remember that 1% corresponds to 3.6°. You can simply multiply the percentage by 3.6 to find the angle. Here, \(15 \times 3.6 = 54\).
The funds distributed in 1992 for youth development were approximately
)380,000
View Solution
Step 1: Understanding the Concept:
This question requires us to calculate a specific amount of money from a pie chart by taking the given percentage of the total funds for that year.
Step 2: Detailed Explanation:
1. Identify the relevant data for 1992.
From the 1992 pie chart, the percentage for Youth Development is 15%.
The total funds distributed in 1992 were
(2.54 million, which is
)2,540,000.
2. Calculate the amount.
We need to find 15% of
(2,540,000.
Amount = \(0.15 \times 2,540,000\)
Let's perform the multiplication:
\[ 0.15 \times 254 = 38.1 \]
So, \(0.15 \times 2,540,000 = 381,000\).
Alternatively, using mental math:
10% of 2,540,000 is 254,000.
5% of 2,540,000 is half of 10%, which is 127,000.
15% = 10% + 5% = 254,000 + 127,000 =
)381,000.
3. Compare with the options.
The calculated amount,
(381,000, is approximately
)380,000.
Step 3: Final Answer:
The funds distributed for youth development in 1992 were approximately
(380,000.
Quick Tip: When the question asks for an "approximate" value, you can often round the numbers to make the calculation easier. For instance, calculate 15% of
)2.5 million: \(0.15 \times 2.5 = 0.375\) million, which is
(375,000. This value is very close to option (C).
The increase in the amount of money distributed for family support from 1992 to 1993 was closest to which of the following?
If all of the emergency assistance funds in 1993 were distributed among 40 groups, which of the following is closest to the average (arithmetic mean) amount distributed per group?
The curve above consists of three semicircles: AB, BC, and CD. The diameter of AB is 2, the diameter of BC is twice the diameter of AB, and the diameter of CD is twice the diameter of BC. What is the total length of the curve?

What is the cost, in cents, of using a certain fax machine to send n pages of a report if the total cost for sending the first k pages is r cents and the cost for sending each additional page is s cents? (Assume that n > k)

Soft Drink Manufacturer: Our new children's soft drink, RipeCal, is fortified with calcium. Since calcium is essential for developing healthy bones, drinking RipeCal regularly will help make children healthy.
Consumer Advocate: But RipeCal also contains large amounts of sugar, and regularly consuming large amounts of sugar is unhealthful, especially for children.
In responding to the soft drink manufacturer, the consumer advocate does which of the following?
Over a period of several months, researchers attached small lights to the backs of wetas—flightless insects native to New Zealand—enabling researchers for the first time to make comprehensive observations of the insects' nighttime activities. Thus, since wetas forage only at night, the researchers' observations will significantly improve knowledge of the normal foraging habits of wetas.

Question 9 is based on the following graph.
Which of the following, if true, contributes most to an explanation of the change in ice cream sales?
People whose bodies cannot produce the substance cytochrome P450 are three times as likely to develop Parkinson's disease, a disease that affects the brain, as are people whose bodies do produce this substance. Since cytochrome P450 protects the brain from toxic chemicals, toxic chemicals probably play a role in the development of Parkinson's disease.
Which of the following, if true, most strongly supports the argument?
The early universe contained only the lightest elements, hydrogen and helium. Heavier elements, such as carbon, form only in nuclear reactions in stars and are dispersed when the stars explode. A recently discovered gas cloud contained carbon several billion years ago, when the universe was no more than two billion years old.
If the statements above are true, which of the following must, on the basis of them, also be true?
Sleep deprivation is a known cause of workplace error, and many physicians frequently go without sleep for periods of 24 hours or more. However, few of these physicians have, in the course of a routine examination by a peer, been diagnosed with sleep deprivation. So there is little cause for concern that habitual sleep deprivation will cause widespread physician error.
The answer to which of the following questions would be most helpful in evaluating the argument?
Which of the following could be the order, from first through seventh, in which the performers sing?
If there are exactly four performers who are to sing after Nelson sings but before Strapp sings, Harris must be assigned to time slot
If Williams is to sing immediately after Harris sings and immediately before Trevino sings, which of the following performers could be assigned to time slot 6?
If Jones is to sing immediately before Harris sings, which of the following must be assigned to time slot 7?
If McIntyre is to sing immediately before Strapp sings, Trevino could be assigned to which of the following time slots?
If McIntyre is assigned to time slot 4, which of the following must be true?
Which of the following can be the trees planted along the side of the street that has four trees, in order of their positions beginning with position 1?
There seems to be a slight confusion in the prompt here, as the pattern shows a total of seven trees. The question "the side of the street that has four trees" might refer to the row 1-3-5-7. I will assume this is the case.
If red oaks are used, then which of the following must be true?
Among the trees left over after the planting is done there must be
View Solution
Step 1: Understanding the Concept:
This question asks what must be true about the set of unplanted trees, regardless of which valid planting arrangement is chosen. We need to consider all possible valid combinations of two tree types.
Step 2: Detailed Explanation:
There are three possible pairings of two tree types:
1. Red Oaks and Sycamores: We have 3 red oaks and 4 sycamores available, for a total of 7 trees. To plant 7 trees, we must use all of them.
- Trees left over: 0 red oaks, 0 sycamores, 4 maples.
2. Red Oaks and Maples: As determined in the previous question, it's impossible to plant 4 maples and 3 red oaks while satisfying the maple rule. So this combination is not possible.
3. Sycamores and Maples: We have 4 sycamores and 4 maples available, for a total of 8 trees. We only need to plant 7. This means we must plant some combination of sycamores and maples, and one tree will be left over.
- Can we plant 4 maples and 3 sycamores? No, it's impossible to place 4 maples.
- Can we plant 3 maples and 4 sycamores? Yes, this is possible. Let's try to place 3 maples. e.g., at positions 1, 4, 7. This is a valid placement. The other 4 spots would be sycamores.
- Trees left over: 1 maple, 0 sycamores, 3 red oaks.
- Can we plant 2 maples and 5 sycamores? We only have 4 sycamores available, so this is impossible.
- Can we plant 1 maple and 6 sycamores? Impossible, not enough sycamores.
- Can we plant 0 maples and 7 sycamores? Impossible, not enough sycamores.
Summary of Leftover Trees in all Possible Scenarios:
- Scenario 1 (Oaks + Sycamores): 4 maples are left over.
- Scenario 2 (Maples + Sycamores): 1 maple and 3 red oaks are left over.
In every single possible planting scenario, there are always maples left over. In one case there are 4, in the other there is 1. Therefore, there must be at least one maple left over.
Evaluate the options:
(A) at least one maple: True in all scenarios.
(B) at least one red oak: False in Scenario 1.
(C) at least one sycamore: False in both scenarios.
(D) at most one maple: False in Scenario 1.
(E) at most one red oak: False in Scenario 2.
Step 3: Final Answer:
In all valid planting combinations, there is always at least one maple tree left over.
Quick Tip: For "must be true" questions that don't provide a new condition, you must consider all possible valid scenarios allowed by the original rules. The correct answer is the only statement that holds true in every single one of those scenarios.
If maples are planted, the side of the street that has four trees must have
A list of the fifteen operas most frequently performed in recent times includes no works by the nineteenth-century German composer Richard Wagner. Although music producers tend to produce what audiences want, relative infrequency of performance probably does not indicate lack of popularity in Wagner's case, since Wagner's operas are notoriously expensive to perform on stage.
Which of the following, if true, most strongly supports the conclusion of the argument above?
The bodies of dwarf individuals of mammalian species are generally smaller in relation to those of nondwarf individuals than are the teeth of the dwarf individuals in relation to those of the nondwarf individuals. Fragmentary skeletal remains of an adult dwarf woolly mammoth were recently found. The teeth are three-fourths the size of the teeth of an average adult nondwarf woolly mammoth.
The statements above, if true, most strongly support which of the following?
Excluding purchases by businesses, the average amount spent on a factory-new car has risen 30 percent in the last five years. In the average household budget, the proportion spent on car purchases has remained unchanged in that period. Therefore the average household budget must have increased by 30 percent over the last five years.
Which of the following is an assumption on which the argument relies?
