Step 1: Look for clues in the sentence. The phrase "so she can watch television now" tells us the homework is already complete and this affects the present moment. Step 2: Identify the correct tense. The present perfect tense (has/have + past participle) is used when a past action has a result or effect on the present. Aisha has finished her homework → the result is that she can now watch TV. Step 3: Form the present perfect. Subject: Aisha (third person singular) → use "has" Past participle of "finish" → "finished" Answer: has finished
