  Filip: which group?
  Wojtek: not sure, it was about a cat
  Janek: you have to be more specific
  Wojtek: when you had those free spaces, did you use vocabulary unchanged
  Janek: no, you have to agree that with number and case
  Wojtek: shiiit
  Filip: gotta go, comparing answers stresses me out
target: Wojtek put a wrong answer in exercise 5 where the vocabulary should have complied with number and case.
