A.I. Explanation:

Option 1: "way"

Explanation: The word 'way' does not fit the context of the sentence. The sentence is discussing Lenny's hair, specifically its thinning state, and 'way' does not provide a relevant description of the location or condition of his hair.

Option 2: "time"

Explanation: While 'time' is mentioned in the text, it does not accurately complete the sentence regarding Lenny's hair. The context requires a specific term related to the part of the head where his hair is thinning.

Option 3: "crown"

Explanation: The term 'crown' is the correct answer as it refers to the top part of the head where hair is typically styled or where thinning can be most noticeable. This aligns perfectly with the context of Lenny's hair situation.

Option 4: "week"

Explanation: The word 'week' does not fit the context of the sentence. The sentence is focused on the condition of Lenny's hair rather than the frequency of haircuts, making 'week' an irrelevant choice.
