Question

Pick the correct question tag from the options. 
People shouldn't drink and drive, ____

Accepted Answer

Here's a detailed explanation for the given question:

**Explanation for the Correct Option (Option 2):**

The correct question tag for the sentence "People shouldn't drink and drive," is **"should they?"** (Option 2). This follows the standard rules for forming question tags:

1.  **Polarity Rule:** If the main clause is negative, the question tag must be positive. Conversely, if the main clause is positive, the question tag must be negative. In the given sentence, "People **shouldn't** drink and drive," the word "shouldn't" (should not) makes the main clause negative. Therefore, the tag must be positive.
2.  **Auxiliary Verb Rule:** The question tag uses the same auxiliary (or modal) verb as the main clause. In "People shouldn't drink and drive," the modal verb is "should." So, the tag must also use "should."
3.  **Pronoun Rule:** The pronoun in the question tag must match the subject of the main clause. The subject of the main clause is "People." The appropriate pronoun for "People" (plural, third person) is "they."

Combining these rules:
*   Negative main clause ("shouldn't") requires a positive tag.
*   Modal verb "should" is used.
*   Subject "People" becomes pronoun "they."

Thus, the correct positive tag is "should they?"

**Explanation for the Incorrect Options:**

1.  **Option 1: "should not they?"**
    This option is incorrect because it violates the polarity rule. The main clause "People shouldn't drink and drive" is negative. A negative main clause requires a positive question tag. "should not they?" is a negative tag, making it grammatically incorrect in this context.

2.  **Option 3: "isn't it?"**
    This option is incorrect because it uses the wrong auxiliary verb and pronoun. The main clause uses the modal verb "should," not "is." Also, the subject is "People," which requires the pronoun "they," not "it." Question tags must reflect the auxiliary verb and subject of the main clause.

3.  **Option 4: "shall they?"**
    This option is incorrect because it uses the wrong modal verb. The main clause uses "should" ("shouldn't"). The question tag must use the same auxiliary or modal verb as the main clause. "Shall" is a different modal verb and does not match "should."
