I am studying for the TOEFL iBT and I have this sample introduction to an independent writing section:
Although some people prefer to work alone, I believe it is much better to work in teams. The benefits for working in teams vastly exceed the convenience of working alone. In my opinion, there are two main advantages to workingto working in teams over working alone.
My question: why does working come after to? I have been taught that after to we must use the "zero verb" or "general" form of the verb.
