There is a problem with 2406 as neither answer choice can be validly inferred.
All successful people have experienced a life-changing event, and most people who have experienced a life-changing event are aware of its impact.
We can infer that...
Most people who have experienced a life-changing event are successful.
Some successful people are aware of having experienced a life-changing event.
Let's symbolize as follows:
All successful people have experienced a life changing event
= S ---->L
most people who have experienced a life-changing event are ware of its impact = L most A
There is no way to validly infer, as the purported answer does, that S some A. It could be the case that though the majority of L's are A, it just so happens that the S's never are. It's a classic invalid formulation.
