Explanation:

In writing, a topic sentence refers to the most important sentence in a paragraph, because this sentence that summarizes all the ideas of a paragraph or the sentence that expresses the point a paragraph is trying to explain or develop. This idea can be identified because it is usually the first sentence in the paragraph or is placed at the beginning of it and because this sentence encloses all the content presented.

Considering this, in the paragraph presented the topic sentence is "Leonardo was fascinated with human anatomy" not only because this is the first sentence, but because it summarizes the content of the paragraph considering other sentence such as "He conducted medical research in hospitals in Florence and Rome" or "For example, he made detailed drawings of a human fetus and a human heart" explain this topic sentence.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
