| Q 1 | If ‘→’ denotes increasing order of intensity, then the meaning of the words [simmer → seethe → smolder] is analogous to [break → raze → ________]. | (B) obliterate | The words "simmer," "seethe," and "smolder" each represent a rising level of heat. Similarly, "break" connotes a gentle form of destruction, whereas "raze" implies greater destruction, an actual sacking. To identify a word for greater destruction, we might use "obliterate," meaning to remove something entirely so that no trace of it remains. So, just as the heat gets to be hotter, from simmer, from seethe to smolder, so too does the degree of damage increase from break to raze to obliterate. |
| Q 2 | Which one of the given options is a possible value of x in the following sequence: 3, 7, 15, x, 63, 127, 255? | (D) 31 | Sequence: 2n−1 for n=2,3,4,5,6=31 |
| Q 3 | How many times will the second-hand and the minute-hand of a clock cross each other between 12:05:00 and 12:55:00? | (C) 50 | Crosses: 5 times per hour, 10 mins elapsed = 10 crosses =10 x 5 = 50 |
| Q 4 | In the given text, the blanks are numbered (i)−(iv). Select the best match for all the blanks. From the ancient Athenian arena to the modern Olympic stadiums, athletics (i) the potential for a spectacle. The crowd (ii) with bated breath as the Olympian artist twists his body, stretching the javelin behind him. Twelve strides in, he begins to cross-step. Six cross-steps (iii) in an abrupt stop on his left foot. As his body (iv) like a door turning on a hinge, the javelin is launched skyward at a precise angle. | (D) holds, waits, culminate, pivots | In the sentence, we will use words that are both grammatically and contextually appropriate. The sentence begins with the reference to athletics-creating the singular subject, so it should be "holds" for the first blank. Then we have the crowd-a singular noun-and "waits" has to be right for the second blank. For the third, since it is "six cross-steps," a plural noun, "culminate" works there. Finally, the last " blank refers to "the body," a singular subject, requiring "pivots." The best choices are (i) holds, (ii) waits, (iii) culminate, and (iv) pivots. |
