Choose the word which is different from the rest.

The answer is C. Think.

The other four words are all physical actions that can be performed by humans. Think, on the other hand, is a mental action. It is the process of using one’s mind to form ideas or to solve problems.

Run is the act of moving at a speed faster than a walk, never having both or all the feet on the ground at the same time.

Walk is the act of moving at a slower pace than a run, with both or all the feet on the ground at some point during each stride.

Jump is the act of moving from one place to another by pushing off the ground with one or both feet.

Swim is the act of moving through water using the limbs and body.
