Question

Pick out the correct question tag for the following: 
People shouldn't drink and drive, ____

Accepted Answer

Here's a detailed explanation for the question tag:

**Justification for Option 1: should they?**

Option 1, "should they?", is the correct question tag because it follows the standard rules for forming question tags in English:

1.  **Polarity:** The main sentence "People shouldn't drink and drive" is negative because of the word "n't" (not) in "shouldn't". When the main sentence is negative, the question tag must be positive. "should they?" is a positive tag.
2.  **Auxiliary Verb:** The auxiliary verb used in the main sentence is "should" (from "shouldn't"). The question tag must use the same auxiliary verb.
3.  **Subject Pronoun:** The subject of the main sentence is "People". For a plural noun like "People", the corresponding pronoun used in the question tag is "they".

Combining these rules, a positive tag with the auxiliary "should" and the pronoun "they" results in "should they?".

**Explanation for why other options are incorrect:**

*   **Option 2: shouldn't they?**
    This option is incorrect because the main sentence "People shouldn't drink and drive" is negative. According to the rules of question tags, if the main sentence is negative, the tag must be positive. "shouldn't they?" is a negative tag, which creates a double negative and is grammatically incorrect in this context.

*   **Option 3: isn't it?**
    This option is incorrect for two reasons:
    1.  The auxiliary verb in the main sentence is "should" (from "shouldn't"), not "is". The question tag must use the same auxiliary verb as the main sentence.
    2.  The subject of the main sentence is "People", which is plural. The pronoun "it" is used for singular, non-human subjects or concepts, not for "People". The correct pronoun would be "they".

*   **Option 4: shall they?**
    This option is incorrect because the auxiliary verb in the main sentence is "should" (from "shouldn't"). While "they" is the correct pronoun for "People", the question tag must use the same auxiliary verb as the main sentence. "shall" is a different modal verb and does not match "should".
