A.I. Explanation:

Correct answer: amazingly

Explanation: The adverb 'amazingly' modifies the adjective 'beautiful,' enhancing the description of the moon's surface. It fits grammatically as it describes the extent of beauty, aligning with the context of awe associated with the moon's appearance.

Meaning: Amazingly means in a way that causes great surprise or wonder.

Wrong options:

• jealous: 'Jealous' is an adjective that describes a feeling of envy, which does not fit the context of describing beauty.
• written: 'Written' is a past participle that does not grammatically fit as it does not describe the beauty of the surface.
• recent: 'Recent' is an adjective that refers to something that has happened not long ago, which does not apply to the timeless beauty of the moon.

Correct answer: enabled

Explanation: The verb 'enabled' indicates that Galileo's telescope provided him the capability to observe the moon closely. It fits grammatically as it is in the past tense, matching the narrative's timeframe.

Meaning: Enabled means to make something possible or to give someone the means to do something.

Wrong options:

• artist: 'Artist' is a noun that does not fit grammatically as it does not describe an action related to the telescope.
• amazingly: 'Amazingly' is an adverb and does not fit as a verb in this context.
• lifeless: 'Lifeless' is an adjective that does not describe an action and is irrelevant to the function of the telescope.

Correct answer: lifeless

Explanation: The adjective 'lifeless' describes the surface of the moon, indicating it lacks life. It fits grammatically as it aligns with the context of the moon's appearance before Galileo's observations.

Meaning: Lifeless means without life or vitality.

Correct answer: artist
