Which of the following is a common error in composing a thesis statement?
a. your thesis statement is specific as opposed to general
b. you offer an original perspective on a familiar theme
c. your thesis statement contains two or more central points
d. you focus your thesis statement after you begin writing

Option C.  Your thesis statement contains two or more central points.

Explanation:

A thesis statement is a piece of text that covers what it is being discussed in the text, and it is written for a specific audience. It also identifies the topic being discussed with clarity, meaning it focuses on a single topic or main idea.

Covering two central points is not allowed in a thesis statement.

explanation:

you only need simple sentences to answer this. just answer these questions.

what do you think annie thinks of the mother? do you think annie believes the mother is a fit mother for helen.

what about the father? what would annie think of him? she might not like him, but does she respect him.

how about the son? would annie think he is the only voice of sanity in an insane place?

what about helen herself? this is the key question. how does she see helen? what do you suppose she thought her first job was going to be.

these aren't hard questions. just state the obvious. annie is not that well educated: she just knows what she has to do. write it that way.

you can do it if you've read the book or seen the play or movie.
