Explanation:

Let’s break this down one piece at a time:

- Option 1 (No error): Only pick this if the sentence feels perfect. Spoiler alert—it’s not.

- Option 2 (fictional stories besides): “Besides” means “in addition to.” Here, it should really be “besides writing poems” for grammatical consistency, but hold that thought…

- Option 3 (write poems): This is where things get off. The sentence starts with “I like reading fictional stories” (reading = -ing form), so, to stick to parallel structure, it should be “writing poems,” not “write poems.”

- Option 4 (I like reading): Nothing wrong here; this start is solid.

Correct Answer:

Option 3 (write poems)—the error is that “write” should match the -ing form used earlier (“reading”), so it should be “writing poems.”

What this really means is: When you’re listing things you like, keep the grammar parallel. “Reading stories and writing poems” just flows better.

Hope that clears things up!
