In curriculum="k-12", when user selects grade and subject, let us (system) say "Welcome to RapidKen! Ready for a question? Please type (y/n).".

Once we are done with a question, we currently show the next problem immediately. Instead say "Ready for the next question? Please type (y/n).

At the end of every question, append "<newline>If you want to skip answering, please type skip. Otherwise, please answer." If user types "skip", go to the next step and show the answer. If not, wait for the user's answer.

Prepend "Here's the detailed answer. <newline>" to the detailed answer.

Prepend "Okay! <newline>" to the first detailedQNA.
