To determine which day had the coldest temperature recorded, let's convert all the temperatures to a numerical format:
- Monday: 5° below 0 = -5°
- Tuesday: 0° = 0°
- Wednesday: 2° below 0 = -2°
- Thursday: 3° above 0 = 3°
Now we can compare the temperatures:
- Monday: -5°
- Tuesday: 0°
- Wednesday: -2°
- Thursday: 3°
The coldest temperature is -5°, which was recorded on Monday.
So, the correct answer is Monday.
