Answer:
If a reader wants to evaluate a text, the best question to ask while reading it is:
C. How well do elements of the text help the text achieve its goals?
Step-by-step explanation:
Let's work by eliminating options to find our answer:
A. This is a subjective evaluation of the text, and one that is not exactly helpful. This may be interesting on a personal level. Thus, this option is incorrect.
B. This option is almost good, but it demands a type of knowledge that does not belong to the text itself. We would need to know the author's process of choosing his goals and the context around his writing. This option is also incorrect.
C. This option is CORRECT. When evaluating a text, what we need to analyze is the text's goal, that is, the message it is trying to convey. Then, we read the text and analyze its elements to evaluate how helpful they are in conveying that message.
D. Just like letter A, this is a subjective evaluation. Incorrect.
