To identify which questions have a variable that is qualitative, we need to understand the difference between qualitative and quantitative variables:

- **Qualitative variables** (also known as categorical variables) are those that describe characteristics or qualities and can be divided into categories. They do not have numerical values.
- **Quantitative variables** are numerical and can be measured or counted.

Now, let's analyze each question:

1. **Were the exams open book?**
   - This question has a qualitative variable because it can be answered with categories such as "Yes" or "No."

2. **Are you allowed to use a calculator on the exams?**
   - This question also has a qualitative variable, as it can be answered with "Yes" or "No."

3. **What was the score you earned on the last exam?**
   - This question has a quantitative variable because it asks for a numerical score.

4. **How many questions were on the last homework assignment?**
   - This question has a quantitative variable because it asks for a numerical count of questions.

Based on this analysis, the questions that have a qualitative variable are:

- Were the exams open book?
