1. The problem is to form a question using inversion in French with the elements: "Y", "il", "a", "un ordinateur", "-t-", "dans la classe", and "?". 2. In French, inversion for questions involves switching the subject and verb and adding "-t-" between vowels for pronunciation when necessary. 3. The correct order is: **Y a-t-il un ordinateur dans la classe ?** 4. Explanation: - "Y" is an adverb meaning "there". - "a" is the verb "avoir" (to have) in the third person singular. - "-t-" is inserted for phonetic reasons between two vowels (a and il). - "il" is the subject pronoun. - "un ordinateur" is the object. - "dans la classe" is the prepositional phrase indicating location. - "?" marks the question. 5. So the final question is: $$\text{Y a-t-il un ordinateur dans la classe ?}$$
