問5で(3)の訳が問われているのですが なぜafter等もないのに4時間"後"と訳せるのですか?

試験本番でのこの本での 目標時間 目標時間 Lesson 4 103 次の英文を読んで、後の問1~5の設問に答えなさい(固有名詞はそのまま使用し てよい)。 5 15 分 分 22 分 ◆解答・解説本冊 p.6 Here's a possible strategy to boost" memory-exercise four hours after you learn something. In a study published in the July 11, 2016, Current Biology, researchers found that exercise after learning may improve your memory of the new information, but only if done in a specific time window *2. (In the study, 72 participants learned 90 picture-location associations mentally linking an image with new information in order to improve recall over a 40-minute period. They were then randomly assigned to one of (1) three groups: one group exercised immediately, the second exercised four hours later, and the third did not exercise. The exercise routine consisted of 35 minutes of interval 10/training on a fitness bike at an intensity of up to 80% of maximum heart rate. After 48 hours, the participants' memory was tested while their brains were scanned*4 via MRI*5. Those who exercised four hours after the learning session retained*6 information better than the other two groups. The MRI also showed the hippocampus, the brain region involved with learning and memory, - that (2) 15 was more active when information was recalled correctly. Newly learned information turns into long-term knowledge through a process that requires certain brain chemicals that are released during exercise, but more research is needed to understand (3) this phenomenon. (4) It is also not clear why four hours was more beneficial, or if another time frame might produce a similar 20 effect.

aなのですが、カンマで挟まれた動詞はどうやって訳せばよいのでしょうか?また、recallingは分詞構文ではなくて知覚動詞の heardに対応するものですか?

次の英文を読み、 設問に答えよ。 A child's mind is full of questions. Perhaps the greatest of these are the questions, 'Who am I?', 'What kind of person am I?', 'Where do I fit in?'. These are the questions of self-definition, upon which we base our lives as adults, and from which we make all our key decisions. Because of this, a child's mind is remarkably affected by statements which begin with the words, 'You are'. 2 Whether the message is "You are so lazy" or "You are a great kid," these statements from the important adults will go deeply and firmly into the child's unconsciousness. (A)I have heard SO many adults, overcome by a life crisis*, recalling what they were told as a child: “I am so useless, 人生の中での危機 I know I am.” Psychologists, like many professional groups, tend to complicate things just a little, and call these statements (³)‘attributions'. These attributions crop up* again and again in adult life. "Why don't you apply for the promotion?" "No, I'm not good enough.” "He's just like your last husband. Why did you marry him?" "I am just stupid, I guess.” These words - 'not good enough', 'just stupid' - did not come (c)out of the blue. (a)They are recorded in people's brains because (b)they were said to (c)them at an age when (d)they to question (e)their truthfulness*. I can hear you saying, "children must disagree with the 'you' messages they are given." Certainly children think about the things that are said to them, checking for accuracy. But they may have no comparisons. Sometimes we are all lazy, selfish, untidy, stupid, forgetful, mischievous, and so on. What our parents say is sometimes true of any of us. So, that is why children have no choice but to believe in what thai were unable n 66 e C

接線の単元です。接する⇔重解という記述が引っかかっています。2枚目の写真ではどうしてこの解き方を使っていないのか、と言うのがよくわかりません。
