Sure! Here are the correct words for each gap in the text about Martha going to the supermarket:

1. **B. store**
2. **A. does**
3. **C. on**
4. **C. department**
5. **C. checks**
6. **C. vegetables**
7. **A. cheaper**
8. **B. checkout**

So the completed text would read:

Martha is at the grocery **store** getting ready for a house party. She has a list of what she needs with her as she goes along. The first section she comes to has produce. Martha sees apples, bananas, cherries, grapes, and strawberries. She **does** the list and gets her items. Oh, the bananas are **on** sale now; therefore, she picks 3 bananas.

Next are **department**. She sees potatoes, carrots, tomatoes, onions, mushrooms, and salad in bags. As she is putting her items **checks** her cart, Martha checks the many bags of salad and chooses 2 of them. She pushes her cart ahead.

The next section is meat and **vegetables** such as cheese, butter, and milk. She checks her list. The meat is much **cheaper** than it is normally, so she chooses a 5-pound. Martha then realizes that she has forgotten something. She runs back and gets a container of salt and then rushes to the **checkout** to pay for her goods. She puts her groceries into her car and leaves.
