(4)について This is why にしてしまいました。  This is becauseというようなThis is whyの表現ではだめな理由を教えてください

(60分) Ⅰ 次の英文を読んで、下の設問 (1)~ (11) の語には注が付いています。 に答えなさい。 なお、 Food is fuel. When your body needs energy, you eat. When it doesn't you don't. It should be so simple when you think about it, but that's exactly the problem: us big smart humans can and do think about it, (, introduces all manner of problems and neuroses*. Have you noticed how you always have "room for dessert"? You might have just eaten the best part of a cow, or enough cheesy pasta to sink a gondola, but you can manage that fudge brownie or sundae. Why? How? If your stomach is full, how ice cream triple-scoop b) eating more even physically possible? It's largely because your brain makes an executive decision and decides that, no, you still have room. The sweetness of desserts is a palpable* reward (7)that the brain recognizes and wants so it overrules the stomach. C Exactly {c case is ③ is 4 the this why) uncertain. It may be that humans need quite a complex diet in order to remain in tip-top* condition, so rather than just relying on our basic metabolic systems to eat whatever is available, the brain steps in and tries to regulate our diet better. And this would be fine if that was all the brain does. But it doesn't. So it isn't. Learned associations are incredibly powerful when it comes ( d ) eating. You may be a big fan of something like, say, cake. You can be eating cake for years without any bother, then one day you eat some cake that makes you vomit. Could be some of the cream in it has gone sour; it might contain an ingredient you're allergic to; or (and here's the annoying one) it could be that something else entirely made you throw up shortly after eating cake. out of The disgust eating poiso g And it consider th The brain than food, it doesn't worryingl needlessl one of li shovelin the brai (注) (1) (2

赤線を引いているところがよくわからないのですが、まず、 1、母と議論するのは難しかったとありますが、何についての議論か 2、最後の分の「彼女は首に巻いた〜合図であった」は何を意味しているのでしょうか できれば要約をお願いしたいです🙇

14 第6問 次の文章を読み、下の問いに答えよ。 標準解答時間 9分 depressed. It was not the exam that made her feel that Christine came out of her last examination, feeling way, but the fact that it was the last one; it meant the end of the school year. She dropped in at the coffee 5 as usual, then went home early because there didn't 10 seem to be anything else to do. shop "Is that you, dear?" her mother called from the living room. She must have heard the front door close. Christine went in and sat on the sofa. "How was your exam, dear?" her mother asked. "Fine," said Christine flatly. It had been fine; she had passed. She was not a brilliant student, she knew, but she was hard-working. Her professors always wrote things like "A serious attempt" and "Well thought out but 15 perhaps lacking in energy" on her term papers; they gave her Bs, the occasional B*. She was taking Political Science and Economics, and hoped to get a job with the government after she graduated; with her father's connections she had a good chance. 20 "That's nice." Christine felt, bitterly, that her mother had only a vague idea of what an exam was. She was arranging roses in a vase; she had rubber gloves on to protect her hands as she always did when engaged in what she 25 called 'housework.' As far as Christine could tell, her housework consisted of arranging flowers in vases. Sometimes she cooked elegantly, but she thought of it as a hobby. It was hard, anyway, to argue with her mother. She was so easily upset that it was better to avoid 30 arguing with her.
