The detail from the text that best summarizes the narrator's opinion about the future is:
A. "when I brought myself to look at the dials again, I was amazed to see my progress." (Paragraph 1)
This detail suggests the narrator's amazement and possibly some optimism about the progress they are making, which implies a more positive view of the future. The other options describe the state of the world or nature in a more negative or desolate way, which does not reflect the narrator's opinion about the future.
