To determine the verb forms in the sentences, you can follow these steps:

1. Identify the verb in each sentence. The verb is the main action or state of being in the sentence.

2. Determine the form of the verb by analyzing the word in parentheses ().

Let's go through each sentence and apply these steps:

1. "All of the balloons on the string (popped) except two."
- The verb is "popped."
- The form in parentheses is "popped," which is the past particle form.

2. "Do you (want) to buy those books?"
- The verb is "want."
- The form in parentheses is "want," which is the base form (also known as the infinitive form).

3. "Daniel's dog is (following) the trail to the river's edge."
- The verb is "following."
- The form in parentheses is "following," which is the present participle form.

4. "For thirty years the noon whistle has (blown) exactly on time."
- The verb is "blown."
- The form in parentheses is "blown," which is the past participle form.

5. "The players have (challenged) their parents to a game of soccer."
- The verb is "challenged."
- The form in parentheses is "challenged," which is the past form.

So, to recap:
1. (popped) - past particle form
2. (want) - base form (infinitive)
3. (following) - present participle form
4. (blown) - past participle form
5. (challenged) - past form

I hope this helps you understand the different verb forms in the sentences!
