付箋で貼った2文がどうしてそのような訳になるのかわかりません。

た次の英文を読み, 設問に答えなさい。 (学習院 法学部 2022年) Society is everything. Many of us go through life thinking we are self-made and self-sufficient. Some may credit (or blame) their families for success or failure in life, but rarely do we think about (1) the bigger forces (that determine our destinies - the country we happen to be born in, the social attitudes common at a particular moment in history, the institutions that govern our economy and politics, and the randomness of just plain luck. These wider factors determine the kind of society in which we live and are the most important determinants of our human experience. 2 Consider an example of a life in which society plays a very (X) role. In 2004 I spent time with a family in the Ecuadorian Amazon*. Antonia, my host, had twelve children, and her oldest daughter was about to give birth to her first grandchild. They lived on the edge of the rainforest with no road, electricity, clean water or sanitation*. There was a school, but a considerable distance away, (Y) the children's attendance was irregular However, Antonia was a community health worker and had access via radio* to a doctor in a nearby town who could provide advice to her and others. Apart from this service (arranged by a charity), she and her husband had to be completely self-reliant gathering food from the forest, educating their children on how to survive in their environment. On the rare occasions when they needed something they could not find or make themselves (like a cooking pot), they searched for bits of gold in the Amazon, which they could exchange for goods in a market at the end of a long journey by boat. 3 This may seem like a very extreme and distant example, but it serves to remind us how accustomed we are to the things that living collectively gives us infrastructure, education and health care, laws that enable markets in which we can earn incomes and access goods and services. Antonia and her daughter promised to name the baby (they were Minouche, (2) which was a great honour. I often wonder what kind of life that other Minouche will be having as a result of being born in a very different society. V+ re expecting The way a society is structured has profound consequences for the lives of those living in it and the kinds of opportunity they face. It determines not just their material conditions but also their well-being, relationships and life The structure of society is determined by institutions such astical and legal systems, the economy, the way in which family and community life are organized. All societies choose to have some things left to individuals and others determined collectively. The rules governing how ? those collective institutions operate form what might be called the social contract, which 1 believe is the most important determinant of the kinds of lives we lead. Because it is so important and because most people cannot easily leave their societies, the social contract requires (Z) of the majority and necessary changes ás circumstances change. VF vf ⑤We are living at a time when, in many societies. people feel disappointed by the social contract and (3) the life it offers them. This is despite the huge gains in material progress the world has seen over the last 50 years. Surveys Social contract people

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.
