Question

choose the transition that contrasts, or shows differences.
theres a great new restaurant we could go to. ______, cooking at home would
save us money.
in fact
therefore
on the other hand

Explanation:

The sentence presents two options: going to a new restaurant and cooking at home, and it needs a transition that shows a contrast between these two options. "On the other hand" is used to introduce a contrasting point or alternative, which fits here as we are contrasting the idea of going to a restaurant with cooking at home. "In fact" is used to emphasize or add supporting information, and "Therefore" is used to show a cause - effect relationship, neither of which is suitable for showing a contrast.

Answer:

On the other hand
