Question

1. The taxi fare was too high.
2. The taxi fare was too expensive.
(Which one is right in this case?)

3. After I went through the entry procedure, I could go anywhere in the city.
(Is this sentence right? Do you have other expressions?)

4. Later I had to hand that one to an acquaintance for free.

Thank you for your help. Would you check them, please?

Answer 1

1 is fine. 2 would be better without "too."

3 is fine, yes.

For 4, I don't know what "that one" is -- once I know that, I can see if the sentence makes sense or not.
