Question

students expect their teachers to __________ good behavior at all times. comprehend muster modify exemplify

Explanation:

To solve this, we analyze the meaning of each word:

• "comprehend" means to understand, which doesn't fit the context of teachers and good behavior.
• "muster" means to gather or assemble, irrelevant here.
• "modify" means to change, not what students expect from teachers regarding good behavior.
• "exemplify" means to be a good example of, which makes sense as students expect teachers to show good behavior as an example.
