Based on information contained in the passage, which

Based on information contained in the passage, which of the following chains of events would most closely conform to the classical conception of free will? In the 1980s, neuroscientists studying the brain processes underlying our sense of conscious will compared subjects’ judgments regarding their subjective will to move (W) and actual movement (M) with objective electroencephalographic activity called readiness potential, or RP. As expected, W preceded M: subjects consciously perceived the intention to move as preceding a conscious experience of actually moving. This might seem to suggest an appropriate correspondence between the sequence of subjective experiences and the sequence of the underlying events in the brain. But researchers actually found a surprising temporal relation between subjective experience and objectively measured neural events: in direct contradiction of the classical conception of free will, neural preparation to move (RP) preceded conscious awareness of the intention to move (W) by hundreds of milliseconds. Blank: W followed by RP followed by M, RP followed by W followed by M, M followed by W followed by RP, RP followed by M followed by W, RP followed by W and M simultaneously

Hi Jishu :)

Happy to clarify! You're correct that the passage states that, "W preceded M," or, in other words, that W comes before M. :D And this observation holds true in the correct answer, A.

The key to understanding this question comes from a different part of the passage: "... in direct contradiction of the classical conception of free will, neural preparation
to move (RP) preceded conscious awareness of the intention to move (W)". We can express this observation of sequence of events as

RP --> W --> M

Now, with this in mind, the question is asking which chain of events would most closely
conform to (or match) the classical conception of free will. In the statement above, we're told that RP before W contradicts the idea of free will. So, the sequence that follows the idea of free will will be the opposite of this: W before RP. And that's how we arrive at the correct answer: W --> RP --> M :)

I hope this helps!
