My brother will for a few nights a) provide us up b) provide us in c) put us up d) put us in

Well with this we use process of elimination.

My brother will provide us up for a few nights.

That set of words doesn't make sense so we can cross out A.

My brother will provide us in for a few nights.

This set of words makes a little more sense so we won't be fully crossing out B.

My brother will put us up for a few nights.

Again, this set of words doesn't make sense so C is eliminated.

My brother will put us in for a few nights.

That set of words makes sense.

So now, it is between B and D.

Now it's up to you to decide which fits better.

Hope this helps!
