you enter the one that the application awaits, choose the "most obvious one". There are three evaluation methods available. 1,0: 1 mark for each correct answer
(answering half of the questions correctly gives a success of 50%); 1,-1: addition of 1 mark for each correct answer and subtraction of 1 mark for each false

pairs, one containing the questions (sentences with placeholders for the prepositions to find), the other containing the answers (sentences with the prepositions
