Paragraph Role and Function Practice Test

Read the passage and answer: What is the primary function of the third paragraph?

Paragraph 1: Cities are warming faster than nearby rural areas, a pattern known as the urban heat island effect. Pavement and dark rooftops absorb sunlight during the day and release heat slowly at night. As a result, summer evenings in cities can remain uncomfortably hot even after sunset. This matters because prolonged heat can strain energy systems and affect daily life.

Paragraph 2: Several features of city design intensify this warming. Trees and soil, which cool the air through shade and evaporation, are often replaced by concrete and asphalt. Tall buildings can trap warm air by limiting breezes at street level. In addition, air conditioners and vehicles release waste heat, adding to the temperature rise.

Paragraph 3: Scientists study heat islands by combining ground sensors with satellite images that measure surface temperature. They compare readings from parks, residential blocks, and commercial districts to see how land use changes heat levels. Because weather varies from day to day, researchers collect data over many weeks to find reliable patterns. This careful method helps separate local design effects from broader regional climate trends.

Paragraph 4: Understanding these patterns leads to practical solutions. Planting street trees, installing reflective roofs, and creating “cool pavements” can lower temperatures noticeably. Some cities also open cooling centers and adjust work hours during heat waves. When planners use evidence from heat studies, they can design neighborhoods that stay safer and more comfortable.

Read the passage and answer: How does the second paragraph contribute to the overall argument of the passage?

Paragraph 1: Many consumers want to buy products that last, but it can be hard to judge durability in a store. A backpack may look sturdy, yet fail after a few months of use. To address this problem, some companies now publish repair guides and sell replacement parts. This practice supports a growing “repair culture.”

Paragraph 2: Repair culture is based on the idea that objects should be maintained, not quickly discarded. When people fix a torn strap or replace a zipper, they extend a product’s useful life. This can reduce waste and lower the demand for constant manufacturing. It also encourages consumers to understand how products are constructed.

Paragraph 3: Critics argue that repair is not always practical. Some items are designed with sealed components or specialized screws that require unusual tools. In other cases, the cost of professional repair approaches the price of a new item. These obstacles can make repair feel inconvenient.

Paragraph 4: Even with these challenges, repair culture can influence design. If customers value repairability, companies may choose simpler parts and clearer instructions. Schools and community workshops can teach basic skills, making repair less intimidating. Over time, small choices about maintenance can add up to meaningful reductions in waste.
