Yes, I'm sure. In the sentence "The swimming pool in my neighborhood is closed for the winter," the word "closed" is a past participle functioning as an adjective to describe the noun "pool."
In contrast, the other sentences do not contain participles that function as adjectives. Here’s a quick review:
- "The swimming pool in my neighborhood is closed for the winter." (Adjective)
- "The teacher is grading papers at her desk." (Gerund functioning as part of the verb phrase, not as an adjective)
- "Katrina is wandering around the school looking for her brother." (Gerund functioning as part of the verb phrase)
- "Mr. Wallace is meeting the principal to discuss the exam schedule." (Gerund functioning as part of the verb phrase)
So, the original choice is correct. If you have further questions or need clarification, feel free to ask!
