I have trouble with many words on audio. So many sound exactly the same to me. I get stuff wrong quite often on the "Type what you hear" things because I can't tell the difference between so many words! It's very frustrating. Worse is when we get words in audio that we haven't even heard in the lesson yet!
There's more than one possibility, but here are the first examples I can think of.
I've just finished three hours of difficult gardening work. But what do i get for it? A mere thank-you and a glass of iced tea. That's okay with me because it's a labor of love.
I've just given a fruit seller, at the market, my last five kroner. What do i get for it? Hopefully a very large container of bringebær!
