Answer:

The correct answer to the given question "He ____________ in Italy at the moment. (work)" is "is working".

Explanation:

In English grammar, the present continuous tense is used to describe an action that is happening at the moment of speaking. It is formed by using the present tense of the verb "to be" (am/is/are) followed by the present participle form of the main verb.

Subject-Verb Agreement:

In the given sentence, the subject is "He," which is the third-person singular form. According to subject-verb agreement, when the subject is in the third-person singular form, the verb form should also be in the third-person singular form. Therefore, the correct form of the verb to use is "is."

Present Continuous Tense:

To form the present continuous tense, we need to use the present participle form of the verb "work." In English grammar, the present participle form of a regular verb is formed by adding "-ing" to the base form of the verb. Hence, the present participle form of "work" is "working."

Combining the Verb Forms:

By combining the correct form of the verb "to be" (is) and the present participle form of the verb "work" (working), we get the correct answer "is working."

Example Sentence:

Using the correct answer, the complete sentence would be "He is working in Italy at the moment." This sentence indicates that the person referred to as "he" is currently employed or engaged in some work in Italy.
