1. My grandparents often visit us on Sundays. In this sentence, the correct answer is A - visit. This is because the verb "often" indicates a habitual action, and when we talk about a habitual action in the present, we use the base form of the verb. So, it should be "visit" instead of "visits," "visiting," or "to visit."

2. Look! He is eating ice cream. In this sentence, the correct answer is B - is. This is because we use the present continuous tense (verb "to be" + verb + -ing) to talk about actions happening right now or at the moment of speaking. In this case, the action of eating ice cream is happening at the moment, so we use "is" before the verb "eating."

3. Linda often takes care of her little sister. In this sentence, the correct answer is D - takes. This is because the adverb "often" indicates a habitual action, and when we talk about a habitual action in the present, we use the base form of the verb. So, it should be "takes" instead of "to take," "taking," or "take."

4. Jane is helping me with my homework right now. In this sentence, the correct answer is D - is helping. This is because we use the present continuous tense (verb "to be" + verb + -ing) to talk about actions happening right now or at the moment of speaking. In this case, the action of helping with homework is happening at the moment, so we use "is" before the verb "helping."

5. Do your parents go to work by bus? In this sentence, the correct answer is A - Do. This is because we use the auxiliary verb "do" in questions for the present simple tense. So, when asking a question about a habitual action in the present, we use "do" before the subject and the base form of the verb. Therefore, it should be "Do" instead of "Does," "Are," or "Is."

6. Does your brother exercise regularly? In this sentence, the correct answer is B - Does. This is because we use the auxiliary verb "does" in questions for the present simple tense when the subject is he, she, or it. So, when asking a question about a habitual action in the present for "he" or "his," we use "does" before the subject and the base form of the verb. Therefore, it should be "Does" instead of "Don't," "Are," or "Isn't."
