The adjective is read. fashion, magazine, and jane are all nouns
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 think it would be the third option because it has a significant less amount of punctuation that the others?
