Here are the statements about the controlling idea of a text that are true:
1. <span>It includes the topic of the text.
2. </span><span>It includes the author’s viewpoint.
3. </span><span>It is the underlying message of the text.
4. </span><span>It is comparable to the theme (for a work of fiction).
Controlling ideas are your own (or in this case, the author's) personal opinions about a topic.</span>
"like tears on a child's dirty face" is a figurative language
Who/Whom are pretty much the same thing... but, whom would be used in a different type of sentence so A.
