Can someone please help me?

A. Replace the word "and" with "that"

Explanation:

This sentence isn't completely grammatically correct, because we can't properly determine what the part was put forth by Charles Darwin nearly 160 years ago refers to. We could think that it refers to the general theory currently recognized as biology's conceptual framework, when it, in fact, refers to the theory of evolution (is that of evolution = is the theory of evolution). That's why we need to replace the word and with that - so that the given part is more obviously connected to the theory of evolution.

i love romeo and xo

it is a!

not b because i don't see how this would make them look dangerous..

not c because that just doesn't make sense..

and not d because this too doesn't make sense, it does not really put the audience on edge in my opinion.

a makes the most sense, romeo's statement that in staying to speak to juliet he is risking his life, leads the audience to worry about his safety. obviously if he says that if he stays, he will be at risk, so of course this makes the audience worry for his safety!

answer is a) romeo's statement that in staying to speak to juliet he is risking his life, leads the audience to worry about his safety.

since it is asking for her reaction to elnora's trouble at school you can rule out any answers with a positive response (b). then you can rule out (d), this is because it does not show the mother's reaction but the daughter's response. that leaves you with two options (a) and (c), by looking at the options you can rule out (c) because it isn't referring back to elnora's issues at school.
