Someone before you had a similar thread a few years ago, you should check out some of the answers there:

Sounds like a test question.

Has something to do with life cycle calculation.

True and the last one is false.

I actually did that in college on a 10 question pop quiz, because I felt that a student was copying off of me, after which I turned in the correct answers.

When the professor returned the scores, the professors called out the grades, and when he got to the student that I suspected, the professor's response was wtf is this?

This student asked why I didn't get an 'F' also because I had the same answers as him...... oops. he was gone shortly afterwards. Do I have an ethics issue?

That's diabolically clever. It's hardly an ethics issue, if anything, it was your ethical duty to ensure he didn't get (what I assume was) a 100% mark just for being able to look at someone's paper.

a 100% mark just for being able to look at someone's paper.

Some people are good at it, frankly, I never did have good eyesight or being discreet about it. And I always admired how they got away with it as well as their 20/20 vision...... I myself felt would always get caught...

But if he would have took the time and read the question, no way was it true and false, especially when it took the whole class time to do it....... too many clues somethings not right.

And it was actually the second time I did it........... The first time was in high school as a freshman in Geometry or Algebra.... I did it to one of my friends.......

Hey what are friends for?........

Anyways he made me feel like such as tool. Unfortunately, he got me back at something but I can't remember what, which or how......... too many pay backs.

But it was very satisfying.......

For example, suppose you are talking about generators. 2x100% means that each generator can handle the whole load, so only one needs to run at a time. 2x50% means that each can handle only 50% of the load, so that both would need to run, leaving no spare. You didn't mention 3x50%, which would be a sensible choice.
