Answer 2

Got it! Here's the corrected version of the sentences:

"Don't go to Nick's place now, he is working. He will finish his homework at seven o'clock. If you come after seven, he will be very glad."

Explanation:

1. "he (to work)" should be changed to "he is working" to indicate that he is currently in the process of working.

2. "He (to finish) his homework at seven o'clock." should be changed to "He will finish his homework at seven o'clock." This indicates a future action, so we use the future tense "will."

3. "If you (Co come) after seven, he (to be) very glad." should be changed to "If you come after seven, he will be very glad." Both parts of the sentence should use the future tense "will" to be consistent with the time reference at seven o'clock.
