How do you know why the caged bird sings in this memoir maya is rased be her mother
Even though you didn't give us the fragment with the comma slice, it isn't really necessary here as we can answer just based on these 4 options here. All options apart from the second one are correct - only the second option doesn't fix the mistake of the comma splice, whereas the other options do but connecting the sentences properly.
Answer:
D. sentence 3
Explanation:
The topic sentence of the paragraph should introduce the topic of the text in an interesting way known as the hook. The current first sentence does not introduce anything, it just jumps into the topic and is confusing. However, sentence 3 introduces the fact that a different type of moose exists in a region of the world. This explains what the paragraph will be about and makes more sense. Therefore, it is the best topic sentence presented.
I would go with B. although because if you think and read. the sentence it make the most sense. hope this helps :)
