{Question. Paragraph Below)
Which of the following details comes from supporting evidence?

There is debate about alien life.
There is no life on other planets.
Earth oceans are very large.
Mars has become very cold.

Answer 1

The secular cooling that must someday overtake our planet has already gone far indeed with our neighbour. Its physical condition is still largely a mystery, but we know now that even in its equatorial region the midday temperature barely approaches that of our coldest winter. Its air is much more attenuated than ours, its oceans have shrunk until they cover but a third of its surface, and as its slow seasons change huge snowcaps gather and melt about either pole and periodically inundate its temperate zones. That last stage of exhaustion, which to us is still incredibly remote, has become a present-day problem for the inhabitants of Mars.

Answer 2

I think maybe A? But not entirely sure.

Answer 3

You may be right but I would say C.
