Here are two more multiple-choice questions (MCQs) for English grammar practice, along with explanations for each answer:
---
### **1. Which sentence uses the correct article?**
A) She is an university professor.
B) She is a university professor.
C) She is the university professor.
D) She is university professor.
**Answer: B) She is a university professor.**
**Proof:** The word "university" starts with a **consonant sound** (/juː/), so the correct indefinite article is **"a"** (not "an," which is used before vowel sounds). "The" would only be used if referring to a specific professor.

### **2. Choose the grammatically correct sentence:**
A) The book who I borrowed is very interesting.
B) The book which I borrowed is very interesting.
C) The book that I borrowed it is very interesting.
D) The book whom I borrowed is very interesting.
**Answer: B) The book which I borrowed is very interesting.**
**Proof:**
- **"Which"** is the correct relative pronoun for objects (like "book").
- **"Who"** and **"whom"** are used for people, not objects.
- **Option C** is incorrect because "it" is redundant (the relative pronoun "that" already refers to "the book").
