Answer 2

1. I am not sure if he will go to the museum. In this sentence, the verb "go" is in the future tense, so we use the future tense form "will go" to express the uncertainty.

2. I shall ask him to buy me these cards, if he goes to the museum. In this sentence, the verb "go" is in the present tense, so we use the present tense form "goes" to indicate a possible action.

3. I do not know if Granny will bake a cake. In this sentence, the verb "bake" is in the future tense, so we use the future tense form "will bake" to express the uncertainty.

4. I'll have lunch at home if Granny bakes a cake. In this sentence, the verb "bake" is in the present tense, so we use the present tense form "bakes" to indicate a possible action.

5. Daniel will visit his grandparents tomorrow if he is free. In this sentence, the verb "be" is in the present tense, so we use the present tense form "is" to indicate a possible condition.
