英検2級の要約とライティングの添削をお願いしたいです🙇‍♀️すごく字が読みにくいと思うんですが よろしくお願いします💦

以下の英文を読んで,その内容を英語で要約し、解答欄に記入しなさい。 ●語数の目安は45語~55語です。 解答は,解答用紙のB面にある英文要約解答欄に書きなさい。なお, 解答欄の外 に書かれたものは採点されません。 解答が英文の要約になっていないと判断された場合は, 0点と採点されることが あります。 英文をよく読んでから答えてください。 University students often plan for their future careers by attending job fairs or searching online for information about different kinds of work opportunities. There are other ways, too. Some of them choose to join short-term work programs at companies called internships. These have some good points. Students will be able to know more about companies they are interested in, such as what kind of jobs there are and what kind of people are working there. Also, internships allow students to get to know other students. These students can encourage each other both during and after the internship. On the other hand, if students choose to join very short internships, they may not be able to understand the job they are doing before the internships end. Also, students who take part in internships may find it difficult to do well in their studies. University students have their future careers. They many things about things about companies and are interested a enable students to find chances to join interships for know other students who in those too. However, they can not understand the job and they confuse their way to study if they join internships only a few days.

以前画像3枚目の様に修飾限定予告のthatというものを習ったので今回もその形なのかと思い、それらのと入れずに訳してしまったのですがこのthoseの識別は文脈判断ということでしょうか? 教えて頂きたいです。よろしくお願いいたします。

実理 K The starting point for today's *meritocracy, of course, is the idea that intelligence exists and can be measured, like weight or strength or fluency in French. The most obvious difference between intelligence and these other traits is that all the others are presumably changeable. If someone weighs too much, he can go on a その人 →Heyで受けるのが一般的 5 diet; if he's weak, he can lift weights; if he wants to learn French, he can take a course. But in principle he can't change his intelligence. There is another important difference 原則として MV between intelligence and other traits. Height and weight and speed and strength and サフィス体例 関係性が強い文がくる even conversational fluency are real things; there's no doubt about what's being 間違いなん measured. Intelligence is a much murkier concept. Some people are generally (2) m2 Vogue 10 smarter than others, and some are obviously talented in specific ways; they're chess 天才 S masters, math *prodigies. But can the factors that make one person seem quicker than another be measured precisely, like height and weight? Can we confidently say that one person is 10 percent smarter than another, in the same way we can say he's 10 へんて、いつだっ S percent faster in the hundred-yard dash? And can we be confident that two thirds of 櫂へん 言いかえ 15 all people have IQs within one standard deviation of the norm that is, between 90 ように and 110 - - as we can be sure that two thirds of all people have heights within one standard deviation of the norm for height?
