avenue or approach
Hi,
I wonder if there's any difference between avenue and approach in the meaning of "a way of getting something done", e.g.
Governments should prioritize the preventive avenue over curative one when allocating budget for preventing future and treating current illnesses.
Actually, the use of "avenue" sounds a bit odd to me but I'm not sure if I can use this word in some academic writings.
Thank you for your help.
