Question

Choose the correct option: The man ______________ his appearance completely since then.

• A. is changing
• B. changed
• C. has changed
• D. is changed

Answer 1

The Correct Option is C

The completion of the sentence "The man ______________ his appearance completely since then." requires the present perfect tense to indicate an action that has occurred at some indefinite time in the past and is relevant to the present. The most suitable tense for this context is the present perfect, which is formed using "has" or "have" followed by the past participle of the verb.

Options Analysis:

• is changing: This is present continuous tense, used for actions happening right now or ongoing processes. It doesn't fit because "since then" implies a completed action at some point in the past.
• changed: This is simple past tense, which indicates a specific moment in the past. However, it doesn't connect the past action with the present as "since then" implies.
• has changed: This is present perfect tense, which is the correct choice as it signifies an action completed at some point in the past with relevance to the present.
• is changed: This is a passive construction, unsuitable here since it incorrectly implies someone other than the man altered his appearance.

Thus, the correct sentence is: "The man has changed his appearance completely since then."
