`{:("Quantity A","Quantity B"),(p+q,q+r):}`

Options

A. Quantity A is greater.
B. Quantity B is greater.
C. The two quantities are equal.
D. The relationship cannot be determined from the infromation given.

Answer

To solve the problem, we need to compare Quantity A (p + q) and Quantity B (q + r) given the conditions \(0 < p < q < r\).

### Step-by-Step Solution:

1. **Understand the Inequalities**: We know that \(p\), \(q\), and \(r\) are positive numbers such that \(p < q < r\). This means \(p\) is the smallest, followed by \(q\), and \(r\) is the largest.

2. **Add \(q\) to the Inequality**: Since \(p < q\), we can add \(q\) to all parts of the inequality:
\[ p + q < q + q < q + r \]
This simplifies to:
\[ p + q < 2q < q + r \]

3. **Analyze the Result**: From the inequality \(p + q < q + r\), we can conclude that:
\[ p + q < q + r \]
This shows that Quantity A (p + q) is less than Quantity B (q + r).

4. **Conclusion**: Therefore, we can conclude that Quantity B is greater than Quantity A.

### Final Answer:
- Quantity A (p + q) is less than Quantity B (q + r), so the answer is that Quantity B is greater.
