Answer 1

Answer:

I don't know what I m doing this weekend b, but I will go to London

Answer 2

I don't know what I'm doing this weekend, but I might go to London.​

Explanation:

The sentence is the future form of tense. This brings in the auxiliary in the future tense.

• The sentence implies a condition using the conjunction 'but', the narrator doesn't know what he is doing for the weekend but there's a slight possibility of him going to London.
• The modal auxiliary 'might' shows a future possibility of the narrator going to London.
• Correct usage of modal auxiliaries gives a clear and deep possibility of things happening.
