Bloom refers to the appearance of dull, white patches on a polished surface, often caused by moisture or chemical reactions between the surface and its environment. This defect is common in finishes such as varnishes or lacquers, which are often used on furniture, wooden surfaces, and even some decorative items. The cause of bloom is typically moisture that gets trapped within the coating layer, leading to a cloudy or dull appearance on the surface. Bloom can also occur due to temperature fluctuations or high humidity, which can cause the applied finish to react with the air or contaminants. Once the moisture evaporates, it can leave behind a milky, uneven patch. While bloom may not damage the material underneath, it ruins the aesthetic quality of the surface. Regular maintenance and careful control of the environment during application can help minimize this defect. Quick Tip: To avoid bloom, ensure proper ventilation and control temperature and humidity levels when applying finishes.

Distemper is a water-based paint that is primarily used for interior walls. It is a traditional paint formulation consisting of pigments mixed with water, chalk, and a binding medium like glue. The claim that distemper is more durable than oil paints is incorrect. In fact, oil paints are known for their greater durability, resistance to wear and tear, and ability to withstand environmental factors like moisture and dirt. Distemper, being water-based, is more prone to fading, peeling, and damage over time. Distemper paints are easy to apply and provide a smooth, matte finish, but they are not as durable or resistant to cleaning compared to oil-based paints. While distemper provides a good reflective coating, it does not offer the long-term protection that oil paints provide. Distemper is often used in dry, indoor environments and is suitable for areas with limited traffic, as it does not offer the same durability as oil-based paints. Quick Tip: Distemper is suitable for indoor use but is less durable than oil paints and should be used in low-traffic areas.

M10 is a grade of concrete that corresponds to a mix ratio of 1 part cement, 3 parts sand, and 6 parts coarse aggregate. This mix is typically used for low-strength applications such as pavements, footpaths, and non-structural works. The grade of concrete is determined by the compressive strength it achieves after 28 days of curing. For M10 grade concrete, the mix ratio ensures that the strength is around 10 MPa (megapascals), which is sufficient for non-load-bearing applications. The correct proportions are essential to ensure the workability, strength, and durability of the concrete. The mix ratio is determined based on the type of work being done, the materials available, and the expected loads on the concrete. Quick Tip: M10 concrete is typically used in low-strength applications like footpaths or for non-structural purposes.

The slump test is conducted to measure the workability of concrete, particularly for reinforced cement concrete (RCC) work. It helps assess the consistency and flowability of the mix. For normal RCC work, the recommended slump range is between 80 mm and 150 mm. This range provides an optimal balance between the ease of mixing, placing, and compacting concrete, while ensuring that it has the required strength and durability. A slump value below 80 mm indicates stiff concrete that may be difficult to work with, while a slump value above 150 mm indicates a very wet mix that may result in segregation and reduced strength. Quick Tip: The ideal slump range for normal RCC work is between 80 mm and 150 mm to ensure the right balance of workability and strength.

Tax Incremental Financing (TIF) is a financing method used to fund infrastructure development. In the Hyderabad model, it is primarily used for urban infrastructure projects, such as storm water drains, roads, and parks, by leveraging the future increase in property taxes generated by these infrastructure improvements. The future property tax revenue resulting from the enhanced infrastructure is used to repay the investment made in the development of these facilities. This approach helps to raise funds without relying on immediate government budgets. TIF is not typically used for funding education, land acquisition, or institutions, making option (A) the correct answer. Quick Tip: Tax Incremental Financing is an effective way to fund urban infrastructure improvements by using the future increase in tax revenue generated by those improvements.

The "missing middle" in housing refers to the gap in the housing market between high-rise apartment buildings and single-family detached homes. It focuses on providing medium-density housing options such as duplexes, townhouses, and small apartments. This type of housing offers an affordable and sustainable alternative that can accommodate a larger portion of the population without requiring large land areas, addressing the needs of growing urban populations. The missing middle is not specifically about high-rise housing, social housing, or eco-sustainable housing, although these types of housing can overlap with this concept. Quick Tip: The missing middle housing concept fills the gap between high-rise apartments and single-family homes by providing medium-density options like townhouses and small apartments.

Old Delhi, with its narrow, winding streets, bustling markets, and historical urban fabric, developed organically over centuries. It was not designed according to any modern urban planning principles but evolved over time based on social and economic needs. In contrast, New Delhi, Dwaraka sub-city, and Chandigarh were all planned cities, developed with the help of urban planners and architects, with defined layouts, infrastructure, and zoning systems. Organic development refers to cities that grow and evolve over time without a formal planning structure, and Old Delhi is a prime example of this. Quick Tip: Old Delhi is an organically developed area, characterized by its historical urban fabric and lack of modern planning features.

Landslides caused by geologic factors typically result from the weak strength of materials beneath the surface, such as loose soil, clay, or unstable rock formations. This reduces the stability of the slope, causing it to fail and result in a landslide. While excavation of slopes and cutting/filling near streams can trigger landslides, these factors are typically considered human activities or environmental disturbances rather than geologic causes. Geologic factors related to landslides are primarily driven by the characteristics of the earth's materials, such as weak or loose soil layers. Quick Tip: Weak materials beneath the surface are the primary geologic cause of landslides, leading to slope instability.

To withstand flooding, shelters and settlements should be sited above the expected flood level. This ensures that the structures remain safe during flood events, preventing water from entering and causing damage. Siting in low-lying areas or on uncompacted ground increases the risk of flooding and instability. Rectangular configurations may be useful for design, but the elevation above flood level is the most crucial factor. Flood-resistant construction and proper site selection are key to minimizing the impacts of flooding on residential areas. Quick Tip: To protect against flooding, buildings should be sited above the flood level to ensure safety and minimize water damage.
