Cách sử dụng
"Reduce to doing" means that you have to do something that you might not necessarily want to do, but it is necessary. It is usually used when you have tried other ways but have no other options left. For example, if you have been trying to solve a problem using different methods, but none of them are working, you may have to reduce to doing the simplest method or the last resort. The expression can be used in both formal and informal situations.
