Paragraph Comprehension Question

Which type of question is the following reading comprehension question?

-Why did the author write this piece?

In my ASVAB prep course, one of the concepts I review for Paragraph Comprehension is the type of questions that are presented. There are a number of different types of questions presented in the Paragraph Comprehension section of the ASVAB.  As an ASVAB tutor, I present tips on how to look for the answers to the different types of questions.  After providing ASVAB math help in my sessions, I present tips for the Paragraph Comprehension section and review vocabulary for the Word Knowledge section of the ASVAB.

Do you know what type of question this is:

-Why did the author write this piece?

The answer will be presented tomorrow.
