Question

which of the following is performing vigorously? the musical conductor who waves his baton forcefully. the runner who stretches systematically before a marathon. the soldier who consistently obeys commanding officers. the bank teller who carefully checks her computer logs.

Explanation:

The word "vigorously" implies doing something with force and energy. A musical conductor waving a baton forcefully shows high - energy and forceful action. The runner stretching is more about preparation, the soldier obeying is about discipline, and the bank teller checking logs is about being careful, not forceful or energetic in the same sense as the conductor.

Answer:

The musical conductor who waves his baton forcefully.
