RCB can automatically answer some buildspec questions by examining the answers given for previous questions. This is known as Context-Sensitive Q&A, or answer-forcing.

If RCB determines that a question has only one possible answer, or that a particular question is not applicable based on previous answers, it automatically answers or bypasses that question.

For example, under advanced questions, if you select one of the Oracle Studio compilers on the compiler selection screen, RCB later gives you the option of using either the vendor Oracle default standard library, or the GCC implementation; for all other platforms, the default vendor standard library is assumed and the standard library option screen does not appear.
