Question

drag the missing word into place
the thief tried to the police officer but was not able
to force him away.
collapse
overpower
hijack

Explanation:

To solve this, we analyze the context: the thief tried to do something to the police officer to force him away. "Collapse" means to fall down, which doesn't fit. "Hijack" is about taking control of a vehicle/aircraft, not a person. "Overpower" means to defeat by superior force, which matches the idea of trying to force the officer away.

Answer:

overpower
