To find the mode of the given data set `-3, 4, 0, 4, -2, -5, 1, 7, 10, 5`, we need to determine which number appears most frequently.

### Step-by-Step Solution:

1. **List the Data**: Write down the data set clearly.
- Data: `-3, 4, 0, 4, -2, -5, 1, 7, 10, 5`

2. **Count the Frequency of Each Number**:
- -3 appears **1 time**
- 4 appears **2 times**
- 0 appears **1 time**
- -2 appears **1 time**
- -5 appears **1 time**
- 1 appears **1 time**
- 7 appears **1 time**
- 10 appears **1 time**
- 5 appears **1 time**

3. **Identify the Most Frequent Number**:
- From the counts, we see that the number 4 appears the most frequently, which is **2 times**.

4. **Conclusion**: Since 4 is the number that appears most frequently, the mode of the data set is **4**.

### Final Answer:
