Question

the following question has two parts. first, answer part a. then, answer part b.
part a
which describes the overall text structure the author uses in paragraphs 15 - 17?
compare and contrast
chronological order
problem and solution
cause and effect

Explanation:

To determine the text structure, we analyze the options. "Compare and contrast" focuses on similarities/differences, "chronological order" on time sequence, "problem and solution" on presenting an issue and its fix, and "cause and effect" on reasons and results. Since the question is about text structure in paragraphs (likely from a literary or language - related text), and without the actual paragraphs, but assuming a common scenario where, for example, if the paragraphs discuss how one thing leads to another (cause - effect) or present a problem and its solution, etc. However, since the user hasn't provided the actual paragraphs 15 - 17, we can't give a definite answer. But if we assume a typical case, for example, if the paragraphs are about how a certain action leads to a result, "cause and effect" would be a candidate, or if it's about two things being compared, "compare and contrast". But without the text, we can't proceed further.

Answer:

(Since the text of paragraphs 15 - 17 is not provided, the answer can't be determined. Please provide the text of paragraphs 15 - 17 to get the correct answer.)
