调研方向
No source file or test is identified. Start by locating the Alternative 3 passage in the book sources, then verify the throughput figures and the explanation of parallelism versus efficiency; done means the numerical example and wording clearly reflect the intended calculation.

描述
Efficiency is the (often measurable) ability to avoid wasting materials, energy, effort, money, and time in doing something or in producing a desired result.
Parallelism is increasing the resources we use to solve a task. It has nothing to do with efficiency.
Why parallelism has nothing to do with efficiency? You wrote above that it reduces time. This is exactly an increase in efficiency.

Alternative 3
...
Wow! On a busy night where the bartender works non-stop for a few hours, you calculate that they now
only use just over 20 seconds on an order. You’ve basically eliminated all the waiting. Your theoretical
throughput is now 240 beers per hour.
Why 240? Maybe 180?
However, you realize that you didn’t actually accomplish 240 beers an hour, since orders come
somewhat erratically and not evenly spaced over time. Sometimes, the bartender is busy with a new
order, preventing them from topping up and serving beers that are finished almost immediately. In
real life, the throughput is only 180 beers an hour.
You mean ~120 beers an hour?
