1. He wants to do nothing but go out.
2. He wants to do nothing but to go out.
3. All we could do now is walk home.
4. All we could do now is to walk home.
5. What have I said to make you angry?

Hello, Hiya.:-D
1, 3, 4 and 5 are all correct in my opinion.

I'm not really sure about #2, but I feel "He wants nothing but to go out." might work.

I hope somebody else will shed some light on this matter.


P.S.

I think you meant "Which sentence is incorrect?", and that the word you intended to use is 'include', not 'conclude'.

They are all correct grammatically but #5 is the only natural sentence.

How to make the former 4 sentences be natural?

Thanks!

Thanks!

In my opinion 1 and 5 are correct and natural. For me, 3 would be better with "can" instead of "could" (because of "now'). 2 would be better without the second "to". 4 would be better with "can" and no second "to".
