A.I. Explanation:

Option 1: "There are three rooms in the apartment."

Explanation: This option states that there are three rooms in the apartment, which contradicts the information in the text. The text mentions that every apartment has 'a couple of rooms,' which implies two rooms, not three.

Option 2: "There are two big and one small room."

Explanation: This option suggests there are two big rooms and one small room, totaling three rooms. However, the text does not provide any details about the size of the rooms, only that there are 'a couple of rooms,' which indicates two rooms.

Option 3: "There are two rooms in each apartment."

Explanation: This option is correct as it aligns with the text, which states that every apartment has 'a couple of rooms.' The phrase 'a couple' typically means two, confirming that each apartment indeed has two rooms.

Option 4: "There is one simple and one special room in the apartment."

Explanation: This option implies that there are two rooms with specific characteristics (one simple and one special). However, the text does not mention any such distinctions or characteristics of the rooms, only that there are 'a couple of rooms,' which does not support this claim.
