Here is what I'm thinking currently:
The first sentence is the most important, obviously, since the percentages are mentioned in the question stem. When they ask you to explain the VARIANCE of left-handedness, they want you to explain why the percentage of lefthanded people decreases as age increases, but they also want you to explain why the total percentage of lefties in Boldavia hasn't changed over the years. AC:A offers a pretty plausible explanation.
By saying that men are more likely to be born left-handed, coupled with the fact that they also have a shorter life-expectancy, the percentage of left-handed people born in Boldavia will likely remain the same because men both die earlier than women and are more likely to be left-handed. Further, if this variance has not changed over the years to favor women as lefties, it would make sense that the total proportion has remained the same.
(C) is wrong because ambidexterity has nothing to do with the variance of left-handed people.
(B) is wrong because this is just an insane resolution to come to. Nowhere in the stimulus does it talk about left-handed people and their proclivity, or lack thereof, to accidents.
(D) is wrong because the birthrate decreasing has nothing to do with the CURRENT variance of left handedness in Boldavia, though I could see how this might be an enticing choice.
(E) is wrong because, like D, it could be enticing. But it shows the the percentage of left handed people has never changed, which, if you allowed the final sentence to mean more to the premise set than it does, you might fall for this. However, it still doesn't account for the variance in left handedness or WHY the percentages rise as age decreases.
Now, I personally wouldn't say that A is necessarily the BEST answer choice if you were given a host of others that could account for this variance, but it's the best you're given out of the alternative answer choices supplied to you, so it is the one to choose.
