After eating all the mangoes, he shouldn't complain of stomach, …

Analyze the question

The sentence is: "After eating all the mangoes, he shouldn't complain of stomach ache, __?" This tests question tags.

The concept

A question tag:

1. Repeats the auxiliary (helping) verb of the main statement.
2. Uses the opposite polarity. A negative statement takes a positive tag, and a positive statement takes a negative tag.
3. Uses a pronoun that matches the subject.

Step-by-step solution

• Main statement: "he shouldn't complain" is negative.
• Auxiliary verb: should (shouldn't = should not).
• Because the statement is negative, the tag must be positive: should.
• Subject: he, so the pronoun in the tag is he.
• Tag: should he?

Checking the options

• A. isn't it: wrong auxiliary and pronoun, and the polarity is wrong.
• B. would he: the pronoun is right and the polarity is positive, but the auxiliary should be should, not would.
• C. should he: right auxiliary, right polarity, right pronoun. ✔
• D. should it: the auxiliary is right, but the pronoun should be he, not it.

Correct answer: C. should he

Exam tip: For tag questions, use the "flip and echo" rule. Flip the polarity (negative to positive, or positive to negative) and echo the same auxiliary and subject pronoun. Here that gives shouldn't he → should he.
