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)

【至急】この文章の題名として最も適切なものは何かという問いです。私は、②だと思ったのですが、解答は①です。 よろしくお願い致します。

次の英文を読んで、 問 1 ~ 問8に答えなさい。 (配点50点) Inspired by fierce family battles for the last remaining piece of cake, a team of three high schoolers in southwestern Japan's Oita *Prefecture have invented a device that cuts round cake and pizza evenly, no matter how many pieces are sliced, and their creation won the top prize in the prefecture's invention contest in 2021. The three students are members of the industrial technology club at Oita Prefectural Kunisaki High School. Their clever invention to solve a daily life problem with a flexible *2mindset won the governor's award in the competition and is gathering attention. Twelve students in the electronics department of the school ( 1 ) to the industrial technology club, which has continued to submit works to the invention contest for about 40 years. Five of their creations won prizes in the high school division of the 2021 edition of the competition that was launched in 1941. The top prize-winning device, whose name translates to "Let's kindly divide it up," was invented by second-year students Wataru Onoda, 16, Rinto Kimura, 17, and third-year student Mitsumi Zaizen, 18. It was inspired by bbattles for birthday cake in Onoda’s family. He needed to defeat his rival two sisters in games of rock-paper-scissors to get the last remaining piece because the cake was always cut into eight pieces despite his family having seven members. Based on Onoda's idea to equally divide a cake into seven pieces, Kimura created a drawing and computer program to precisely make parts for the device. While Zaizen could not be involved in the actual production due to preparations for her university entrance she created a video for the presentation, using her experience of winning a prize in the competition for two years in a row. exams, (2 ) a two-month trial and error process, the device was completed. When a cake or pizza is placed on a turntable made with a laser beam machine, it can be cut evenly into
