A. "Astronomers are very confident there is life beyond earth"
Explanation:
An assertion is an allegation or proclamation of something, often as a result of opinion as opposed to fact.
A is a solid example of assertion because it tells the reader that the astronomers very strongly believe that their is life beyond earth. There are no facts to back it up, it is just a statement that reflect the astronomers opinion.
The answer would be B. cause to become seen. This is the correct answer because the definition of captivate is to attract or hold interest. I hope this helps!
