Question

6 He hasn't got a dog, and / but he's got a cat.

Answer 1

He hasn’t got a dog, but he’s got a cat.

Answer 2

The sentence "He hasn't got a dog, and he's got a cat" implies that the person being referred to does not possess a dog, but does have a cat. The conjunction "and" is used to connect the two contrasting statements about the person's pets.

Alternatively, you could also use the conjunction "but" to convey the same meaning: "He hasn't got a dog, but he's got a cat." The use of "but" emphasizes the contrast between not having a dog and having a cat. Both "and" and "but" can be used in this context, but "but" adds a stronger sense of contrast.
