Japanese dates lesson 3 only asks two questions!
The lesson says it's going to teach quite a few different words and phrases about years, but only asks you to translate one sentence to English and then the same sentence from English to Japanese, and the lesson is over!

@Contributors: Issue with "Dates, lesson 3"
As you can see in the comments for that other thread, it's not always that it asks only two questions. Sometimes it does work fine. But there must definitely be a problem with it since this same specific lesson has been brought up again. ^^;
Offline mode is more prone to glitches like this because DL didn't download the full set of words/sentences for you to translate.
