Hmmm, I'm not sure that I follow you on that. Even if
(A) had said "Henrietta is older than Bob, the President of the Australian Scuba Diving Association, so she must be wiser than he is", it would still be incorrect for all the reasons discussed above.
Don't start chasing superficial differences like this, or you'll start to see the LSAT as a terribly arbitrary exam. Stick to strong logical relationships. The rule set out in
(A) only applies to a single person, as that person gets older and older. The stimulus (and
(D)), give a rule that is meant to be universal.

I.e., the thinness level of the air is essentially constant across all regions of equal altitude (physically, I guess this makes sense).
That's exactly it!!
Here's the thing you've got to remember - it doesn't matter if that rule is
actually true in real life. It's a
PREMISE. We have to accept premises as gospel truth.
So, yes, in real life perhaps other things contribute to the thinness of the air (and other things probably contribute to the number of rings a tree has), but these two arguments hand us a tightly wrapped rule that we should not question: "The bigger X characteristic is, the bigger Y characteristic is."
Don't bring in your outside biases about how air thinness is actually determined. The premise, as written, suggests a blanket rule that applies in all situations - and significantly, it applies to all situations at once: for any point A that is higher than a point B, point A will have thinner air.
The blanket rule in
(A) does apply to all people - but only to
one person at a time. Every person is wiser than their younger self, but we can't use this rule to compare two
different people.
I hope this helps clarify a few things!
