Critical Reasoning (CR) | Re: Researchers have concluded from a survey of people aged 65 that emotio

GMATNinja - What is wrong with Choice (A) here? How is it easy to eliminate as irrelevant? If people who are older start thinking about mortality and start confronting feelings of loneliness and isolation as a result, then wouldn't this offer us an alternative explanation for why people's emotional well-being is affected negatively as they age (aside from intimacy from their siblings earlier in life)? All we have from the passage is mere correlation: "Those surveyed who had never had any siblings or who said that at college age they were emotionally distant from their siblings were emotionally less well adjusted at 65 than were those who had been close to at least one brother or sister". This is not enough to say that lack of intimacy with siblings earlier in life leads to less emotional adjustment at 65 than with intimacy with siblings earlier in life does. Need some help with thisone.
