Short Answer 
The analysis establishes that Kevin and Mark cannot be the manager due to their carpooling with him, and Tom cannot be the manager since he watches TV with him. This leaves Jerry as the only candidate remaining for the manager position, confirming he is the correct answer.
Step 1: Analyze the Carpool Situation
In the given scenario, we know that Kevin and Mark are carpooling with the manager. This important detail indicates that neither Kevin nor Mark can be the manager themselves. Thus, two candidates are left: Jerry and Tom.
Step 2: Examine the TV-Watching Scenario
Next, we learn that Tom watches TV with the manager. This further clarifies the situation because if Tom is watching TV with the manager, he cannot be the manager. So this narrows our options down to only one candidate for the manager role.
Step 3: Conclude with the Correct Answer
Having established that Kevin and Mark are not the manager and that Tom is also not the manager, we conclude that the only possible person left for the manager position is Jerry. Therefore, Jerry is the correct answer, as he fits all the criteria provided and is the only remaining option.
