Choose the option that best completes the sentence. Maryam, the girl in my neighbourhood, treats people as if she _____ better than they are.

In English grammar, when we refer to hypothetical or unreal situations, especially when expressing actions or states using 'as if', we often use the subjunctive mood. The subjunctive mood reflects wishes, hypotheticals, demands, or suggestions. In this case, "treats people as if she _____ better than they are," denotes a hypothetical situation. **Maryam is not actually better; it is just a hypothetical situation.**

For such hypotheticals in English, we typically use 'were,' regardless of whether the subject is singular or plural. Hence, the correct completion of the sentence is, Maryam, the girl in my neighbourhood, treats people as if she **were** better than they are.

Thus, "**were**" effectively completes the sentence because it aligns with the grammatical rules applied for hypothetical or unlikely conditions. This makes **"were"** the correct choice.
