Identify the most appropriate ANTONYM of the underlined word in the given sentence.
The door was ajar and a faint wisp of smoke floated through it.

The correct answer is Lot.

Step-by-step Explanation:

1. Analyze the underlined word in context:
In the sentence, "The door was ajar and a faint wisp of smoke floated through it," the word faint acts as an adjective describing the "wisp of smoke". Here, faint means slight, small, barely perceptible, or minimal in amount or intensity.

2. Define the antonym requirement:
We need to find an antonym, which is a word that has the opposite meaning of faint (slight/small amount/weak).

3. Evaluate the given options:
• Itchy: Having or causing an itch; irrelevant to the concept of amount or intensity.
• Lot: A large amount or number. This directly opposes the meaning of faint (which refers to a tiny, barely noticeable amount/intensity). Therefore, "lot" is the most appropriate antonym among the choices.
• Trickle: A small flow or thin stream. This is a synonym or closely related concept to a "faint wisp", rather than an antonym.
• Wind: Air in natural motion; unrelated to the opposite of faint in this context.

Therefore, Lot is the correct antonym representing a large quantity, contrasting with the small, weak presence of a faint wisp.
