Correct Answer: Puzzle

Solution : The most appropriate synonym is the first option.

Explanation: In the context of the sentence, the word baffle is used to convey the essayist's intention to confuse or perplex his readers. Puzzle aligns closely with this meaning, indicating the act of creating confusion or difficulty in understanding.

Therefore, the correct synonym is puzzle .

The meanings of the other options are as follows:

• Influence : It refers to the capacity to have an effect on someone or something.
• Scold : This word is unrelated and does not capture the meaning of intentionally confusing readers.
• Annoy : While this word suggests causing discomfort, it does not specifically convey the sense of confusion or bewilderment that "baffle" does.
