Question:

Select the proper Präposition Die Katze schläft ____ dem Sofa. a. zu b. durch c. auf d. nach

Giulia H.
Answer:

The correct answer is c. Die Katze schläft auf dem Sofa, meaning the cat sleeps ON the couch. Answers a. and c. are incorrect, because they indicates that the verb is directional, sleeping is not a directional action. Answer d. is incorrect, because it means after, which does not make sense in this sentence.
