問題文
各大問の英文や図表を読み、最も適当な選択肢を選びなさい。
You are working on an essay about space exploration. You will follow the steps below：
Step 1：Read a range of opinions gathered from the Internet about exploring outer space.
Step 2：Take a position on space exploration.
Step 3：Create an outline of your essay using additional sources.
▶［Step 1］Read a range of opinions
Apu（university professor）
The exploration of space requires a lot of research time and money. All this research has led to many new inventions and boosted humanity’s scientific and technical knowledge. While laser eye surgery，solar cells，freeze−dried food，and wireless headsets are just a few examples that have come out of space research，perhaps the invention that has proven the most useful in modern life is the computer mouse. This was developed in the 1960s on a NASA research project.
Christine（company CEO）
Much space exploration relies on international cooperation，a good example being the International Space Station，launched in 1998. The main reasons for this cooperation are to share the huge costs involved and to improve national prestige. More recently，private companies have begun exploring space，though mostly for commercial reasons. In the future，it is possible that countries or corporations will try to colonize parts of the moon or Mars. While financial cooperation and raising prestige are welcome，improper commercial or military use of outer space is not.

As the famous physicist，Stephen Hawking，once said，it is probably dangerous to broadcast into deep space evidence of the existence of humans here on Earth. If our nearest intelligent aliens are anything like us，then they will seek to conquer Earth and humanity. For me，this is the greatest threat associated with space exploration. The deeper into space we travel，the greater the likelihood Earth will be discovered by an aggressive alien civilization.
Naomi（lawyer）
Historically，jobs working at sea were likely the least safe，with the highest rates of death in the workplace. In modern times，space is no different，if not worse. Once we are just 10，000 meters or so above the surface of the Earth，there is little oxygen and the temperature is too low for human survival. Since the first person went into space in 1961，19 of 652 astronauts have died on the job： a fatality rate of 2.9％. No other business or industry would tolerate such a high level of danger. Why should the space industry？
Victor（financial analyst）
Space exploration has contributed hugely to economic growth. In the USA，NASA provided work for nearly 340，000 people in 2021，mostly at above−average salaries，and it is estimated that it has contributed $7.7 billion in taxes to the US government. Space is also being explored by other countries，such as China，India，Japan，and Russia. In the future，further economic growth will be ensured by more private firms entering the space race and by the rise of space tourism，space mining，space colonization，and space militarization.
▶［Step 2］Take a position
Now that you have understood the various opinions，you have taken a position on space exploration and written some notes below. Choose the best options to complete （ 42 ）.
POSITION： Space exploration is not a good idea.
●（ 40 ） and （ 41 ） opinions support this the most.
● An argument common to these two people is that （ 42 ）.
