Final answer:
The logical operator you should use if you want two tests to both be true is AND.
Step-by-step explanation:
The logical operator you should use if you want two tests to both be true is AND. The AND operator is represented by the symbol '&'. When using the AND operator, both conditions must be true in order for the overall statement to be true. For example, if you have two tests, Test 1 and Test 2, and you want to check if both of them are true, you would use the AND operator like this: Test 1 & Test 2.
