Question

what does the evidence supporting the big bang theory assume about the universe when it began? select the two correct answers. (1 point)
it was extremely hot.
it was very tiny.
it was composed of ice.
it was contracting

Explanation:

The Big Bang theory posits that the universe began as a singularity - an extremely hot and very tiny (extremely dense) point. "It was composed of ice" is incorrect as the early universe was hot and energetic, not icy. "It was contracting" is wrong because the universe has been expanding since the Big Bang, not contracting initially. So the correct assumptions are that it was extremely hot and very tiny.

Answer:

A. It was extremely hot, B. It was very tiny
