26. To be admitted to the university, he---------------to make an application by May 15.
Answer: A
He has to make an application by May 15 to be admitted to the university.
Using "has" correctly indicates that he is required to make an application by a specific deadline for admission.
A) Has
This option is correct because "has" is the appropriate verb form to indicate that he is obligated or required to make an application. It aligns with the subject "he," thereby maintaining proper subject-verb agreement.
B) Have
This option is incorrect because "have" does not agree with the singular subject "he." The proper form should be "has" to denote the requirement in the context of the sentence.
C) Might
This option is incorrect as "might" suggests possibility rather than obligation. The context indicates a requirement rather than an uncertain or optional action.
D) Should
This option is incorrect because while "should" implies a recommendation or duty, it does not convey the same level of obligation as "has." The context requires a definitive requirement, which "has" fulfills.
Conclusion
The answer "has" is definitively correct as it establishes a clear obligation for the subject to apply by the specified date. All other options fail to meet the grammatical requirements or the intended meaning of the sentence, confirming that "has" is the only suitable choice.
