Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

What is coevolution?
Coevolution occurs when the fitness of two different species is tightly linked and these two species evolve in response to evolutionary changes in each other.
