To be alive after such a serious accident … a celebration.

Analyze the question The sentence is: "To be alive after such a serious accident _ a celebration." We need the verb form that agrees with the subject and fits the meaning.

Explain the concept The subject is the infinitive phrase "To be alive after such a serious accident". An infinitive phrase used as a subject is treated as singular, so it takes a singular verb. The verb must also be active, because the subject is the thing that calls for (demands) a celebration, and "a celebration" is the direct object.

Step-by-step solution

1. Subject: "To be alive after such a serious accident" (singular).
2. Object: "a celebration". Since there is a direct object, the verb must be active and transitive.
3. Check each option: • A. is called for: passive. It cannot take the object "a celebration", so it is wrong. • B. call for: plural/base form, which does not agree with a singular subject, so it is wrong. • C. has been called for: passive again, with the same object problem, so it is wrong. • D. calls for: singular, active, present tense. It agrees with the subject and means "demands/deserves a celebration", so it is correct.

Answer: The sentence reads: *To be alive after such a serious accident calls for a celebration.

Tip: In JAMB concord questions, first find the real subject. Phrases beginning with "to..." or "-ing" are singular. Then check whether an object follows the gap. If one does, choose an active verb, not a passive one.
