Can someone explain this question? I don't understand it at all- first of all why would people need internal sunscreen? Like for the indoors? And if they mean internal- meaning orally, shouldn't an option be topical vs. internal? I don't understand this...

Caitlin, sorry, I don't have a better explanation than the one provided in the hint / solution.

Do they mean topical? Topical cream is, by definition, applied externally. An internal medication would be something like a pill. Tropical makes little sense in the context.

Guys, I agree that this question can be misleading. Internal can be understood as "indoor" or something to be taken inside your body, i.e., "oral". I will suggest to the app admin to get rid of this practice problem.

The claim that sunscreen is used in tropical and not polar regions is just wrong. The reflective nature of snow and ice can cause a sunburn just as badly as on a beach near water. This should be topical as that is the opposite of internal.

Matt, you are right. This question has been removed because it was not well written. It will be reflected in the next update.
