Question

1. in paragraph 10, the author includes the sentence \only time will tell!\ to emphasize that —

no one knows when the time capsule will be revealed again
preservation methods to protect the time capsule are unreliable
the time capsule may be forgotten and lost to history
people who open the time capsule in the future will find it valuable

Explanation:

To solve this, we analyze each option:

• Option 1: "Only time will tell!" implies uncertainty about when the time capsule will be revealed again, as time is needed to know.
• Option 2: The sentence doesn't relate to preservation methods' reliability.
• Option 3: It's not about the capsule being forgotten, but about when it'll be revealed.
• Option 4: The sentence doesn't emphasize future value, but uncertainty about timing.

So the best fit is the first option.

Answer:

A. no one knows when the time capsule will be revealed again
