Grammar

Thanks for reporting this inconsistency, we'll make sure to fix it asap. Your understanding is correct: Stadt is closer to the word City because it means a much bigger place than Dorf, which means Town. Thanks again and enjoy the rest of the program!

in means both inside something or toward something, if you say in die kneipe it means "to the bar", if it's in der kneipe it means "in the bar", if you choose in die kneipe then it should be followed by for example gehen cause it's a motion. (er ist in die kneipe gegangen). remember ist here is for the past tense and not exaclty a to be verb to describe an is situation if that makes sense. I know this is one of the most difficult things in the language especially, I am level 3 and still mix things up sometimes. if someone is better than me at this feel free to correct me too I also need a lot of help for my German learning! Good luck!

Hi Jillfrost, Thanks a lot for pointing this out. You understood the use and place of "nicht" well, your example phrases are all correct. In the last one, you couldn't follow it up with "sondern im hotel bleiben", you'd have to add the subject again, so it's more complex.
One option could be: Wir gehen morgen ins Schimmbad nicht ; doch wir bleiben stattdessen im Hotel" Now, about the workout you're mentioning from the program, you're totally right that you can't guess where to place the "nicht" here, only in the last sentence (Wir mochten heute Abend nicht zu Niklas' Feier gehen, sondern in ein Restaurant). So for this phrase the contents team will take care of adding all possible options for "nicht", we'll let you know when this update is available.
Thanks for your comment again! Hope you're enjoying the rest of the program!
