Grammar Correction for Saira's Appeal

The original sentence is: "How do Saira appeal to the examiners?". The goal is to replace the underlined part ("do Saira") to make the sentence grammatically correct.

Subject-Verb Agreement Explanation

The core issue in the sentence is subject-verb agreement, specifically in forming a question in the simple present tense.

• The subject of the sentence is "Saira", which is a third-person singular noun.
• When asking a question in the simple present tense about a third-person singular subject, the correct auxiliary verb is "does", not "do".
• The standard question structure is: $How + does + [Singular Subject] + [Base Form of Verb]...?$

Analyzing the Options

Let's examine why the other options are less suitable:

• Option 1: $How does$ - This option correctly uses the auxiliary verb "does" for the singular subject "Saira". The sentence becomes "How does Saira appeal to the examiners?", which is grammatically sound.
• Option 2: $How did$ - This option uses the past tense auxiliary verb. It would be correct if the question was about a past event (e.g., "How did Saira appeal yesterday?"), but the original sentence implies a general or present inquiry.
• Option 3: $How does not$ - This forms a negative question ("How does Saira not appeal...?"). This changes the meaning and is not a simple correction of the original positive question structure.
• Option 4: $How has$ - This option uses the auxiliary verb for the present perfect tense. It suggests an action that started in the past and continues or has relevance now (e.g., "How has Saira appealed so far?"). This tense doesn't fit the likely intent of the original sentence.

Conclusion

Based on subject-verb agreement rules for the simple present tense and a singular subject like "Saira", the correct auxiliary verb is "does". Therefore, replacing "do Saira" with "does Saira" is the appropriate correction.

The corrected sentence is: How does Saira appeal to the examiners?
