You are a CEO at a finance firm. One of your managers is up for promotion. You want to make sure that they can discern a good financial offer from a bad one so that they will do well making the company money. You invent an investment proposal and give all the information to the manager in question. You tell them to assess whether or not the company should accept the investment proposal or not. (Your proposal can be good OR bad. Remember you are testing the manager so you don't automatically have to create numbers that would be good for the company.
