B is spot on, async doesn't wait for results!

Synchronous is definitely faster than async.

I feel like B is right since asynchronous doesn't wait for the result, but I'm not completely confident about the wording.

I practiced a similar question where D was marked as correct because it explains the return behavior clearly.

I'm a bit unsure about C; I thought asynchronous execution could be faster in some cases, but maybe it's about how they handle tasks?

I remember that synchronous execution waits for the result, so I think A is definitely correct.

The last option seems to sum it up nicely. I'll focus on that and make sure I understand the difference between the two execution models.

I feel pretty confident about this one. The synchronous service returns the result, while the asynchronous one just kicks off the service and doesn't wait for the result.

I'm a bit confused by the wording on some of these options. I'll need to re-read them a few times to make sure I understand the nuances.

Okay, let's see. I think the key is understanding that synchronous execution waits for the service to complete before returning the result, while asynchronous just initiates the service and moves on.

Hmm, this looks like a tricky one. I'll need to think carefully about the differences between synchronous and asynchronous execution.

This is a classic case of 'read the question carefully.' The correct answer is B, as it accurately describes the key difference between synchronous and asynchronous execution.

Haha, I bet option C was written by someone who's never used async/await before. Synchronous is the slow one, not the other way around!

Haha, yeah, option C is definitely misleading. Async is all about speeding things up!

Option D looks good. The synchronous execution will wait for the service to complete before returning the result, while the asynchronous execution will return immediately and deliver the result later.

I'm not sure about option C. Isn't it the other way around? Asynchronous execution is usually faster because it doesn't block the main thread.

Option B seems correct to me. The asynchronous execution service initiates the service invoking, but does not return the service execution result. That's the key difference between synchronous and asynchronous execution.
