What is the meaning of the word "retreat"?

The word "retreat" primarily means to withdraw or pull back from a situation, location, or engagement. This can refer to various contexts, such as a military withdrawal from combat, a personal decision to step back from a stressful situation, or a general movement away from a previous position. The essence of "retreat" involves the action of moving backward, often in response to pressure or conflict, which aligns with the choice that signifies withdrawing.

In contrast, the other choices do not capture this essence. "Provide" suggests an action of supplying or making available, "contain" implies holding something within limits, and "anger" refers to a powerful emotion, none of which relate to the concept of moving back or away from something. Therefore, the choice that best encapsulates the meaning of "retreat" is the one that signifies withdrawal.
