correct the following subjects -verb agreement,tents and fragments

1 when he thought hecould afford to pay his own school fess

What is the WHOLE sentence?

He thought that he could afford to pay his own school fees.

When he thought he could afford to pay for his own school fees.

To correct the subject-verb agreement, tense, and fragments in the sentence, follow these steps:

Step 1: Identify the subject and the verb.
- Subject: "he"
- Verb: "thought"

Step 2: Check if the subject and verb agree in number and tense.
In this case, the subject "he" is in third-person singular form, so the verb should also be in the third-person singular form. However, the verb "thought" is in the past tense, which is correct.

Step 3: Correct any other errors, such as fragments.
In this sentence, there is a fragment because it is incomplete. It starts with a dependent clause ("when he thought") but does not have an independent clause to complete the thought.

Corrected sentence:
When he thought he could afford to pay his own school fees, [independent thought needed]

Please note that the corrected sentence still requires an independent clause to complete the thought.
