Answer:
During World War II, Roosevelt spoke eloquently, inspiring the nation with his "fireside chats" on the radio.
Explanation:
In writing an effective sentence, the need to refrain from using too much of "to" or "do" in the sentence makes it an unnecessary or too common sentence. Rather, the use of more effective verbs will make the sentence more precise and effective.
In the given sentence, "did a good job" is a good way of talking about the verb but replacing it with "spoke eloquently" provides a more effective structure and verb use.
So, the correct answer is the second option.
