Answer:
There’s a man lying down on the pavement over there. Do you think he <u>may/might have hurt</u> himself?
Explanation:
In the second sentence, modal verbs <em>may </em>and <em>might </em>can be used. These verbs are used to express the possibility of something happening.
The constructions <em>may/might + have + past participle</em> and<em> may/might + be + present participle</em> are used to talk about possible events in the past, present, and future. Since the given event took place in the past (the man is now lying on the pavement because he may have hurt himself earlier), the construction with the past participle will be used. That's how we'll get the sentence:
<em>Do you think he </em><u><em>may/might have hurt</em></u><em> himself? </em>
