What is the most appropriate time to ask each question about a text?

I'd assume right after the text was read?

Explanation:

If this text was read aloud, then the most appropriate time would be right after it was read.

If it was read by just you, then ask your teacher/professor after class.

I'm a little bit confused about the question you're asking, but I hope my answers help.

martians or other types of aliens represent a unique fear as opposed to zombies. vampires and other types of monsters.   in most sci-fi stories, aliens come from other worlds and have different or more advanced technology.   abductions and experimentation on human bodies that involve these technologies, or the use of these technologies against human beings and the use of unknown "powers", are a type of fear that's different from that of other types of monsters.
