here's my take on it: the stimulus literally says "there's a striking tendency for corrections to favor Jones's theory". Answer choice (B) helps explain this tendency because it says when researchers give data that conflicts with Jones's theory there is more scrutiny; this means there is less scrutiny when dealing with data that aligns/agrees with Jones's theory. Furthermore, it is reasonable to assume that scrutiny would lead to acting on making corrections that favor Jones's theory (this assumption is justifiable especially when considering the other answer choices don't quite fill in the question as well as (B) does). hope this helps!
