I've noticed that the LR questions got much easier in the early preptest 40's and that the scales got much tighter... Is this an evolution that we should expect for the June exam as well?
Also.. I have a question on preptest 41 section 3 question 22...
Paleotologist recently discovered teeth from several wooly mammoths on an isolated Arctic island where no mammoth fossils had previously been found. The teeth were 25% smaller on average than adult mammoth teeth that have been found elsewhere, but they are clearly adult mmmoth teeth. THerefore, provided that the teeth are representative of their respective populations, wolly mammoths that lived on the island were smaller on average than those that lived elsewhere.
So the answer is D) tooth size among adults wooly mammoths was always directly proportional to the overal size of those mammals.
my question is... isn't the conclusion of the argument conditional in nature?, "provided that the teeth are representative of their respective populations, wolly mammoths that lived on the island were smaller on average than those that lived elsewhere" seems like an "if then" statement to me, which shields it from having to presuppose the if clause. So for me, answer b), the tooth wear thatnaturally occurs in many aimals over the course of their audlt years did not result in a significant change in tooth size among adult wooly mammoths a they aged.
Can someone explain this to me?
Have a great day everybody
