問2についてです。 解説の黄色の線が引いてあるところが理解できません。

次の英文を読んで, (1) Considerable attention has been paid to the size or relative size of the human brain. The first point of interest is that the ratio of brain weight to body is at a maximum at birth and decreases with age, reaching a fairly steady level by maturity. In other 5 words, newborn babies have very large brains, relatively speaking, weighing some 300 grams. This is roughly the size of the brain Children and their brains continue of an adult male chimpanzee. to grow for many years, gradually increasing their ability to learn and remember. There have been suggestions that the growth of 10 the brains of children is not steady, but occurs suddenly, each period of rapid growth ( 2 ) associated with a particularly important developmental or intellectual stage. These stages could be the ability to reason abstractly, to talk, or even to do arithmetic. The idea of sudden brain growth is still around, but 15 has not attracted much enthusiasm. Some research has shown differences in the relative sizes of the brains of males and females of the same age, but so far no great differences have been found between people of the same age but of different ethnic groups. Obviously the brain of a 20 small Japanese teenager is very much smaller than that of a giant Russian boy. But when brain size is adjusted for size or weight of the body, there ( 3 ) great advantage for either with respect to intelligence. Moreover, in measuring intelligence one has, of course, to take into account the effects of education 25 and cultural background. (4) Individual brain sizes, particularly of famous people, have also 10

Level Passage : 2:30 Lesson 5 Jet Reading 22 ⑤ Questions: 2:00 Compared to dogs and other pet animals, cats often have lots of freedom. Many owners let their pet cats go outside whenever they want to. But where do they go? Does your cat visit your neighbor's house for extra food? How far from home does your cat actually travel? Cat owners have been wondering about such questions for a long time. 5 To find out where cats go and what they do, researchers decided to track them by putting a GPS (Global Positioning System) device around their neck. It is well known that cats are natural hunters. They often chase and catch *wildlife, such as birds and other small animals. It was therefore believed Hoor war301 that cats may go far from their homes to hunt. However, the research showed some surprising facts about cat *behavior. It seems that most cats 10 don't travel very far from their homes. On average, they move around two houses away. Owners were *relieved to hear this result because it confirmed that their cats do not cross major roads. There was another interesting result. One female cat walked more than 1 kilometer from her home. When the owner checked her GPS data, they discovered that the cat had gone to their old house. It showed that cats remember the past longer and more clearly than we think.(219 words) *wildlife 44 *relieve ~を安心させる *behavior Infogt) A Choose the best options.

Tesichts. While Amsterdam's leaders are looking for solutions to these problems, their options are limited. This is because Amsterdam depends so much on tourism that the city cannot survive without it. As a result, city officials are looking for ways to keep the current level of tourism while also reducing the stress that tourism creates. For instance, one idea is to decrease traffic by having tour buses stop at the edge of the city and making tourists travel into the center on public transportation. ( 23 ), Amsterdam may be able to keep the benefits of its tourism industry but avoid many of the negative effects.
