Michel can only guess ___ ___ think. ?

The phrase 'Michel can only guess ___ ___ think' requires words that effectively complete the sentiment of the sentence while maintaining grammatical coherence. Let's analyze the options:

A) "whom/he" - This combination suggests a subject-object relationship, which doesn’t fit the context of guessing thoughts. "Whom" typically refers to an object, while "he" is a subject pronoun, rendering it incorrect.

B) "that/me" - Although "that" can introduce a dependent clause, pairing it with "me" does not appropriately complete the thought. The resulting phrase “guess that me think” is awkward and grammatically incorrect.

C) "who/our" - "Who" is a subject pronoun, and while "our" is a possessive pronoun, this combination does not convey a meaningful idea regarding guessing someone’s thoughts. The phrase lacks clarity.

D) "what/I" - This is the correct choice. "What" refers to the content of thoughts, while "I" serves as the subject pronoun of the speaker. The completed phrase reads "Michel can only guess what I think," clearly indicating that Michel is attempting to predict the speaker's thoughts. This option maintains grammatical correctness and logical clarity, making it the most appropriate choice.
