Question

Quizplus · Accepted Answer

The best answer is B, replicability, because the question is asking about the possibility of repeating the research to determine if lucid dreams involve a mixture of REM sleep and wakefulness. The other options are not as relevant to the question being asked. Correlation versus causation is not relevant because the question is about the possibility of a mix of REM sleep and wakefulness being involved in lucid dreams, not about the relationship between two factors. Falsifiability is not relevant because the question is not about the ability of a theory or hypothesis to be falsified. Extraordinary claims are not relevant because the question is not about making an extraordinary claim.
