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

it was a tug of war between A and D my reasoning was that trees being part of nature and also it has a healthy one state reasoning and between 2 things but still a tough call . IG D and oohlo it's correct

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 - WRONG. Two problems - one that Henrietta must be wiser as she was earlier and other that the case where her daughter might be wiser than she is is also a possibility.

(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. - WRONG. Nothing about beating it.

(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. - WRONG. Charles age factor too might play a role here. People in general might be faster but not necessarily Charles.

(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. - CORRECT. Assumption being that tree are of same species. This hold true just like passage's logic is.

(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. - WRONG. Situation reversal sort of but additional problem of English being difficult in general.

Answer D.
