空欄Aのとこなんですけど選択肢にwhereasとyetがあってその二つの違いがわかんないです 早稲田教育英語2012の大問2です

from injuries due to falls. Poor vision accounts for 18 percent of broken hips. So, why don't more people get regular eye exams? For one thing, eye exams in the United States are not covered by public nor by many private health insurers. Even the new U.S. health care law has yet to include basic eye exams and rehabilitation services for vision loss, though advocates are pushing hard for this coverage in regulations now being prepared. But even those who have insurance or can pay out of pocket are often reluctant to go for regular eye exams. Fear and depression are common impediments for those at risk of vision loss. Patients worry that they could become totally blind and unable to go partying, read or drive a car, he said. [A] many people fail to realize that early detection can result[] vision-preserving therapy. Those at risk include people with diabetes, high blood pressure, high cholesterol or cardiovascular disease, as well as anyone who has been a smoker or has a family history of an eye disorder like macular degeneration, diabetic retinopathy or glaucoma. The eyes are truly a window to the body, and a proper eye exam can often alert physicians to a serious underlying disease like diabetes, multiple sclerosis or even a brain tumor. Mr. Lovett recommends that all children have "a professional eye exam" before they start elementary school. "Being able to read the eye chart, which tests distance vision, is not enough, since most learning dhe is whild de adequate

テーマ 資源・エネルギー 10 文法項目 動名詞(いろいろな形/動名詞と不定詞) Track 29-30 UNIT 6 Reading URELL パンダのふんの研究が、いつの日か環境問題の解決に寄与するかもしれません。 In June, 2016, a baby *giant panda, Tian Bao, was born at a zoo in Belgium. It became big news because the birth of a baby panda is an *extremely Actually, that of Tian Bao was only the sixth in Europe in the last 20 years. While its population is slowly increasing, the giant panda remains one of the rarest animals 5 in the world. Therefore, scientists have been doing research on how pandas have babies. So, you may think the scientists working at the Belgium zoo *accomplished the goal of their research. But they have another goal; apart from having done that research, they've been studying panda *poo. Why are they doing that? Bm Dimoda ro Tian Bao's mother Hao Hao and its father Xing Hui live in the same zoo as their baby does. While they enjoy sitting in the sun and eating bamboo, with ow dirg.or the scientist team collects their poo. By studying the poo, the team is aiming to understand how pandas can digest bamboo. rare event. 2 Note In fact, bamboo is receiving a lot of attention in biofuel research these days. 15 It's among the fastest-growing plants on earth, and yet needs the least care. So the plant can become a good source of *renewable energy. But because bamboo is very tough and hard to *degrade, today's method for making a biofuel from bamboo costs a lot. *Technically, pandas are meat-eating animals, but over the years the food they eat 20 has changed to almost only bamboo. The scientists are trying to find the *microbes that help a panda digest about 10kg of bamboo a day. By using these microbes, they will be able to discover an easy and cheap method for ( 4 ). It may take time, but some day panda poo may help cars run. (296 words)
