Cities are often several degrees warmer than the surrounding countryside, a pattern known as the urban heat island. Dark roofs and pavement absorb sunlight and release it as heat after sunset, while the scarcity of vegetation removes the cooling effect of water evaporating from leaves. Green roofs (layers of soil and plants installed on top of buildings) have been promoted as a remedy. Measurements bear out part of the claim: a planted roof can be dramatically cooler than a conventional one on a summer afternoon. Yet researchers caution that the benefit to the street below is modest unless green roofs are widespread, because most of the cooling occurs at roof level, well above where people walk. For residents, the more reliable gains may come from street trees, which shade the very surfaces pedestrians touch.

Which of the following best states the main point of the passage?

Topic 1.1 · Apply it

Many of the best-known Victorian novels first reached readers not as books but in installments, published monthly or weekly in magazines. Critics have sometimes treated serialization as a commercial constraint that pushed authors toward padding and cliffhangers. Recent scholarship complicates this view. Because installments appeared over many months, readers discussed unfolding plots in letters and reviews, and some authors adjusted later chapters in response. Serialization, on this account, was less a limitation than a conversation: it allowed a novel to be shaped, in part, by the audience it addressed. The skeptics are not entirely wrong, since some serialized novels do sag in the middle, but the form also made possible a responsiveness that the finished, bound book could not offer.

Economists once assumed that people treat money as fully interchangeable: a dollar is a dollar, whatever its source. Studies of "mental accounting" suggest otherwise. People who receive a tax refund, for instance, are more likely to spend it on luxuries than they would be to spend an equivalent raise spread across their paychecks, even though the two sums are identical. The finding matters for policy: how a benefit is delivered may change what recipients do with it.
