"This hospital is spacious."
Yeah, Duolingo can't be arsed to add the kanji except extremely randomly. Reporting seems to do nothing... >-(
Newsflash: japanese was not invented to be directly translated into English. It is a completely different language and we are using English to attempt to understand it. Because of this sometimes words we use will fit different situations. The app is giving you context and different situations. This is better than simply learning one word for another and going out and finding out your Japanese is shit because you're constantly using the wrong word for the situation...
