The higher the altitude, the thinner the air. Since Mexico City's altitude is higher than that of Panama City, the air must be thinner in Mexico City than in Panama City.

Which of the following arguments is most similar in its reasoning to the above argument?

(A) As one gets older, one gets wiser. Since Henrietta is older than her daughter, Henrietta must be wiser than her daughter

(B) The more eggs used and the longer they are beaten, the fluffier the meringue. Since Lydia used more egg whites in her meringue, than Joseph used in his, Lydia's meringue must be fluffier than Joseph's.

(C) The people who run fastest marathons these days are faster than the people who ran the fastest marathons ten years ago. Charles is a marathon runner. So Charles must run faster marathons these days than he did ten years ago.

(D) The older a tree, the more rings it has. The tree in Lou's yard is older than the tree in Theresa's yard. Therefore, the tree in Lou's yard must have more rings than does the tree in Theresa's yard.

(E) The bigger the vocabulary a language has,the harder it is to learn. English is harder to learn than Italian. Therefore, English must have a bigger vocabulary than Italian.

Confused between A and D.

Hi aghosh54,

Here is an explanation from Powerscore for (A):

The problem with (A) is in the premise "As one gets older, one gets wiser." There is correlation between age and wisdom, but they are both qualities of the same person: the older you get (relative to yourself), the wiser you get (relative to yourself). The conclusion in (A) does not reflect the comparison in this premise, because Henrietta's being older than her daughter does not mean that she is wiser than her daughter.

Let's say the daughter is 21 years old, and Henrietta is 41. Maybe during these 21 years the daughter got wiser a lot faster than Henrietta did, whose wisdom increased only incrementally in the course of 41 years. So, it is possible that today they can be equally wise, or that the daughter is even wiser than her mom. In other words, because the premise establishes a positive correlation between two qualities relative to the same person, the rate at which they increased will also be subjective. This does not allow us to compare how wise one person is to another: it only justifies a comparison between how wise that person is today vs. how wise she herself was in the past.

The premise in answer choice (A) should have said "The older one is, the wiser one is." This would have established an absolute, across the board correlation between age and wisdom that would have allowed us to compare the wisdom of one person to the wisdom of another based on their age.

IMO D.

The question stem talks about comparable quantitative values. The altitude and air density both are measurable. Hence, between A and D, D talks about comparable values too - number of years of age, number of rings. Therefore, much more closer to the question stem.

In D, the trees that are being compared can be completely different in their physical characteristics, how can we be sure in this case that the rings formed will be at an equal rate over the same period of time. Also please post the OE for E.

The reason (E) is not a viable solution is because it reverses the reasoning of the original argument. See here: https://forum.powerscore.com/lsat/viewtopic.php?t=4839 and https://www.manhattanprep.com/lsat/foru ... t4640.html
