Step-by-step explanation:
The line that provides the best evidence that Jim has high expectations for himself is option B) He does not strike the mighty blow he sees in his mind.
This line suggests that Jim has a vision of achieving something great, and he holds himself to a high standard. However, he doesn't fulfill this expectation, which indicates that he has high aspirations for himself but is disappointed when he doesn't meet them.
For example, this can be compared to a businessman who believes he deserves a raise but is hesitant to ask for one. Instead, he tells himself that hard work is its own reward. This shows that the businessman has high expectations for himself, but he may struggle to meet them.
