A topic sentence is a sentence that includes the main idea of the paragraph.
It is a sentence that is usually found in the beginning of a paragraph, although not always. It is the sentence that states what the main idea of that particular paragraph is, and then the paragraph is there to support this sentence, not the other way round.
A) hope this is correct and helps
I always see the topic. If it's a known subject that interests me,I analyze the word choice
It would either be B or C, I'm leaning more towards C though.
I'd say A is the answer as the dialect days "We how the corn(?) Since the early morning, Now the sinking sun, Says the day is done."
