"Your friend won medals at the Olympic Games."
Translation:Bhuaigh do chara boinn ag na Cluichí Oilimpeacha.
Hmm, the key word boinn is missing from the supplied "word bank" in this example. Not sure how to report that, other than a comment here.
It's got nothing to do with this exercise, or with the Irish course, it's a display issue with Duolingo on whatever device or platform you're using, so the appropriate reporting mechanism is a bug report, with a screenshot that demonstrates the problem, and full details of the platform that you're using (device, app version, browser version, screen resolution, etc).
If this is happening in the web version of Duolingo, you might be able to workaround the issue by changing the zoom level in your browser.
