So that's what happens when you move two light minutes closer to the Sun. Travel farther out and the problem becomes not heat but cold, as Mars frigidly proves. It, as too, was once a much more congenial place, but couldn't retain a usable atmosphere and turned into a frozen waste. (4)According to the third paragraph, how have we obtained the knowledge of Venus's surface? 本文と一致するものを選べ。 ①It is predicted that our sun will have burned itself in ten million years rather than ten billion years. ②Recent researches have shown that Michael Hart's calculations were much more refined and accurate than they were once thought. ③In spite of the similarity in size and composition, Earth and Venus differ greatly in surface temperatures and atmospheric pressure. ④If Earth had been 5% closer to or 15% farther from the Sun, according to the latest studies, it would have been a more habitable planet with no greenhouse gases. ⑤The closeness to the Sun once made Mars a comfortable planet for the survival of life.
