The correct answer is option 3 i.e. mixes drinks.

Error Concept: The error lies because of the wrong use of "Subject-verb agreement".

What is wrong: The subject “The young men” is plural, so the verbs used must also be plural. The verb “mixes” is singular, which does not agree with the plural subject.

Grammar Concept: Subjects and verbs must AGREE with one another in number (singular or plural). Thus, if a subject is singular, its verb must also be singular; if a subject is plural, its verb must also be plural.

Incorrectness of the concept in context: Since “young men” is plural, both verbs should be in the plural/base form. “Mixes” should be “mix” to match the subject.

Correction: Thus, “mixes” should be replaced with “mix”.

Corrected phrase: mix drinks and pose for photographs.

Final sentence: The young men behind the bar, dressed in black T-shirts, mix drinks and pose for photographs.

The correct answr is option 2 i.e. My grandmother told me that I should respect my parents.

Others: Sentence remains advisory in tone.

Hence, the chosen option is correct.

The correct answer is option 3 i.e. flora and fauna.

Error Concept: related to the use of vague and general terms instead of precise vocabulary.

Grammar Concept:

• The expression “flora and fauna” is the standard phrase used to refer to plants and animals together.

Correction: Thus, “various plants and animals” should be replaced with “flora and fauna.”

Corrected phrase: flora and fauna

Final sentence: It’s a fact that we need to preserve flora and fauna for sustaining the balance of ecosystem on this planet.

The correct answer is option 1 i.e. have submitted.

Error Concept: Subject-verb agreement

What is wrong: The verb “have” is incorrectly used with the subject “Each of the participants.”

Grammar Concept: When “each” is used as the subject, it is always followed by a singular verb. The subject “each” is singular even though it refers to many people.

Incorrectness of the concept in context: The verb “have submitted” is plural, but the subject “each” requires the singular form “has submitted.”

Correction: “have submitted” should be replaced with “has submitted.”

Corrected phrase: has submitted

Final sentence: Each of the participants has submitted their reports, and the results will be announced at the end of this week during the presentation ceremony.
