Question

I wanted to raise my hand to touch her hair (voice change)

Answer 1

To touch her hair my hand touched

Answer 2

The answer will be “My hands were raised intentionally so that her hair could be touched”.  

Here the sentence has been modified in a way that the subject has been turned into the object and the object is being treated as the subject.

From the active mode, the sentence has been turned into a passive mode.

The meaning and the use of tense has been kept unchanged.
