The answer is b. Sentence three talks of choosing pesticides for your garden. It has nothing to do with the benefits gardening brings upon a person. It mentions nothing of stress relief or other health benefits. All of the other sentences describe how gardening can benefit a person. Sentence three does not describe how gardening can benefit a person and therefore it is the off topic sentence.
I just took the test, the correct answer is .. “The woman exudes power and control, while the boy remains meek.”
Answer: C
This sentence is an example of first person, because it uses the word "we."
So, the answer to the question should be answer C. Hope this helps!
