When something like a question or any word or phrase of “jumps out at you”, you notice it because it is interesting, important, etc. Another phrase you can use with the same meaning is “leap out at somebody” Example: while I was looking through the list of names, none of them leapt out at me.

A question jumps out at me One question jumps out at me There is something that obviously needs to be explained. The explanation that I’ve just read or heard has something important missing. They say that their relationship is perfect. The question that jumps out at me is why they don’t see each other more often than once a week. A question jumps out at you for what is missing. What jumps out at me is that they’ve made a decent profit 10 years in a row. (It’s the most important thing)

Thank you!
