問題 3 以下の英文を読んで、次の問いに答えなさい。 (*のついた語には語注が ある。) If you are able to step outside and hear many types of birds, you might also have a greater feeling of well-being. Two studies show that hearing diverse birdsongs may help increase our happiness. (A) One study was done by researchers at California Polytechnic State University. A research team studied the effects of birdsong ( 1 ) people walking through a park in the U.S. state of Colorado. A biology graduate student, Danielle Ferraro, led the study. "There could be an evolutionary reason why we like birdsong so much. And the idea is that when we hear birdsong it could signal safety to us," Ferraro says. There could be many other reasons, too. Ferraro states that in some areas around the world birdsong can also signal the arrival of spring and nice weather. Bird diversity, she adds, can also mean a healthy environment. She explained her study to Voice of America (VOA). Ferraro and her team played recorded songs from a diverse group of birds native to the area. They did this on hiking trails in a park in Boulder, Colorado. (2) several weeks, the researchers played recorded birdsong at certain times of the day and other times they did not. Then they talked with hikers after they ( 3 ). Hikers who heard the recorded diverse birdsongs reported a greater sense of well-being than the people who heard simply the natural birds. The researchers suggest that both the bird sounds and biodiversity* can increase feelings of well-being. Ferraro explained that she used native birdsong for the study. This way it would sound as natural as possible. They also did the study during the summer. She explains why this is important. "So the study ( 4 ) in the summer and that's kind of important because the spring is most birds' breeding* season. And if we play the birdsong during breeding season, that might have disturbed them. (B) We didn't want to disturb the birds too much." The study was published in an academic journal called the Royal Society B in December 2020. - 10- ◇M2 (310-15)

(1)の回答で、OC2が何故正方形の対象軸になるかわからないです。教えて下さい

110 第3章 図形 2の正三角形OAB と3つの二等辺三角形 COA, C2AB, Cabo 1辺6の正方形 PQRS の折り紙がある。 下図のように、 以下の問いに答えよ.ただし, AB は PQ と平行とする。 をかいて切り取り, 三角錐を組み立てることにする.このとき、 63 立体と展開図 (1) 辺ABの中点をM, 直線ABと辺 QR の交点をDとするとき、 6 MD, BD の長さを求めよ。 S (2) CD, BC の長さを求めよ.. (3) 三角錐において, Cから △OABに下ろした垂線の足 をHとするとき, CHの長さ を求めよ. (4) 三角錐 C-OAB の体積V を求めよ. 精講 P A27B D C2 空間図形を考えるときの基本は, できるだけ平面図形としてとらえること R Satin C3 A STSMARTCO だから、立体と展開図の2つをにらみながら解答をつくっていきます (1),(2) まず,必要な部分だけをぬき出した図をかくことが大切です。 次に,直角がたくさんあるので,直角三角形をみつけて, 三平方の定理 三角比の利用を考えます (61). (3) 四面体 C-OAB の条件から, C から底面に下ろした垂線の足Hは△OAB の外心です (62) , △OABは正三角形なので, Hは重心でもあります。 ま た, 垂線を下ろしているので, (1), (2)と同様に直角三角形に着目します。 解答 (1) OC2 は正方形の対称軸で,Mは線分 OC2 上にあるので, MD=123×6=3 MB = 1 だから, BD=3-1=2 (2)△OACと△BAC において C A M あ BA国道 B B
