Cognitive rabbit hole.

“Select things that would cost you more money than shown.”

Well, there’s no money shown, so should I select all of them, or none of them?

Is the reference smartphone the cost of a) the handset, or b) the contract with a carrier? Cos if a, then the planes might be cheaper if c) they represent the price of a short haul ticket, as opposed to d) buying an actual jet airliner.

And what if one of the envelopes has something worth oodles of money in it?
