下線部（1）の文構造が分かりません。特に2行目の文構造が分かりません。強調のdoであることは分かりますが、その後のthat以降が関係詞？かすらも分からないので、誰か教えて下さい！

次の英文は1991年に出版された本からのもので、 研究分野としての「人工知 能」 (Artificial Intelligence) について述べています。 下線部(1)~(3)を日本語に訳 しなさい。 What is Artificial Intelligence (AI)? Just about the only characterization of Al that would meet with universal acceptance is that it involves trying to make machines do tasks which are normally seen as requiring intelligence. There are countless refinements of this characterization: what sort of machines we want to consider; how we decide what tasks require intelligence and so on. One of the most important questions concerns the reasons why we want to make machines do such tasks. AI has always been split between people who want to make machines do tasks that require intelligence because they want more useful machines, and people who want to do it because they see it as a way of exploring how humans do such tasks. We will call the two approaches the engineering approach and the cognitive-science respectively. (2) (1) approach The techniques required for the two approaches are not always very different. For many of the tasks that engineering AI wants solutions to, the only systems we know about that can perform them are humans), so that, at least initially, the obvious way to design solutions is to try to mimic what we know about humans. For many of the tasks that cognitive-science Al wants solutions to, the evidence on how humans do them is too hard to interpret to enable us to construct computational models, so the only approach is to try to design solutions from scratch" and then see how well they fit what we know about humans. The main visible difference between the two approaches is in (3) their criteria for success; an engineer would be delighted to have create something that outperformed a person; a cognitive scientist would regard it as a failure. -1- M7 (492-61

数Iの2次方程式についての質問です。 マーカーで引いてある数字はどこから出てきたのでしょうか？ 分かる方いたら教えて欲しいです🙇‍♀️！

右の図のように, BC=20cm, AB=AC, ∠A=90° の三角形ABC がある。 辺AB, AC 上に AD AE となるように2点D,Eをとり,D,Eから辺BCに 垂線を引き、その交点をそれぞれF,G とする。 長方形 DFGE の面積が20cm² となるとき,辺FG の長さを求めよ。 F CHART & SOLUTION 文章題の解法 基本 66 ① 等しい関係の式で表しやすいように, 変数を選ぶ ②解が問題の条件に適するかどうかを吟味 FG=x として, 長方形 DFGE の面積をxで表す。 そして、 面積の式を =20 とおいた の2次方程式を解く。 最後に, 求めたxの値が,xのとりうる値の条件を満たすかどうか 忘れずに確認する。 答 FG=x とすると, 0<FG<BC であるから A 0<x<20 ① D また, DF=BF=CG であるから 2DF=BC-FG B 20-x よって DF= 2 長方形 DFGE の面積は DF・FG=20-x.x 2 20-x ゆ x=20 2 整理すると これを解いて x2-20x+40=0 x=-(-10)±√(-10)2-1.40 =10±2√15 ここで, 02/15 <8 から 10-8<10-2/15 <20, 2<10+2/15<10+8 よって、この解はいずれも ①を満たす。 したがって FG=10±2√15 (cm) E 定義域 ←∠B=∠C=45° であるか 5, ABDF, ACEG G C 角二等辺三角形。 xの係数が偶数 → 26′型 3章 9 2次方程式 解の吟味。 0<2√15=√60<√64= =8 単位をつけ忘れないよう に。
