Answering yes/no a question with 会。 Can you answer to a question with only the verb of the question?. Is it right if you put an aclaration afterwards?

This is the example.

A- 她会按医生的话去做吗？

B- 会，他决定按医生的话去做。

Thanks in advance.
Yes/no can usually be expressed simply by the verb as you have noticed.


  是不是....
  是





  能不能....
  能


Many learners however like to reply awkwardly with words like 对, if you reply in this manner it would sound much more natural.
