Based on the description:
// Challenge: Change main() so that it returns a Result, and instead of handling the error
// that play_time returns, use the try operator to only handle the success condition. How
// does the output of the program change?
the following change is made:
fn main() -> Result<()> {
...
for dolphin in &dolphins {
let responses = play_time(dolphin)?;
println!("{} did a FABULOUS PERFORMANCE!", dolphin.name);
for response in responses {
println!(" {}", response);
}
}
Ok(())
}
It changes the output of the program to:
Error: The dolphin's name is too long and annoying to say
Did I understand the challenge correctly and was it the correct solution?
Or anything should be done to explicitly ignore the error Result returned by play_time() and yet to consume the Ok Result?
Please advise.

Yes, that's exactly the right output after making the change. You are not the first person to ask this question, so I will go and update the text to make it clear that this is the expected solution!
