Answer 2

It seems like you're trying to convert a past simple sentence into future simple tense. The sentence "I visited my grandmother last Thursday" is already in the past simple tense, describing an action that happened in the past. If you want to rewrite it in future simple tense, you could say:

"I will visit my grandmother next Thursday."

In this sentence, the verb "will visit" indicates a future action that you plan to perform.
