Haziness between "outside" and "common" knowledge
Posted: Sun Sep 18, 2011 7:13 am
Maybe this test is just getting into my head at this point, but I feel as if I have been seeing more questions lately that make me wonder about what exactly constitutes "outside knowledge". The Powerscore books say, for instance, that the location of major cities is something which could be brought in to factor into a question. I was reminded of that when I saw this question from a PT I took today:
According to current geological theory, the melting of
ice at the end of the Ice Age significantly reduced the
weight pressing on parts of the earth’s crust. As a
result, lasting cracks in the earth’s crust appeared in
some of those parts under the stress of pressure from
below. At the end of the Ice Age Sweden was racked
by severe earthquakes. Therefore, it is likely that the
melting of the ice contributed to these earthquakes.
Which one of the following, if true, most strengthens
the argument above?
(A) The earth’s crust tends to crack whenever there
is a sudden change in the pressures affecting it.
(B) There are various areas in Northern Europe that
show cracks in the earth’s crust.
(C) Evidence of severe earthquakes around the time
of the end of the Ice Age can be found in parts
of northern Canada.
(D) Severe earthquakes are generally caused by
cracking of the earth’s crust near the
earthquake site.
(E) Asteroid impacts, which did occur at the end of
the Ice Age, generally cause severe
earthquakes.
I just feel like this question is begging for the "Sweden is so far north! It's certainly plausible that it had glaciers that receded at the end of the last Ice Age!" voice to keep hammering away in one's mind when reading the question. To me this seems to be more along the lines of common knowledge or a plausible assumption that it could be at least possible that Sweden had glaciers which then receded, as opposed to actually knowing for a fact that Sweden was at one point covered in glaciers and then using this information in the question. The OA, D, invites this use of geography even more with the "near the earthquake site", i.e. Sweden, part of the AC (thereby making the answer choice stronger if it is more reasonable that the location of the earthquake and the place where the described geological effect could have happened are one in the same). Also interesting to note that other regions, Northern Canada and Northern Europe, are brought into play here in other incorrect ACs, where knowledge of geography would change the relative strength of these ACs.
Can anyone help me out on situations like these? Anyone else come across a question that they have found to be particularly difficult to determine about just what exactly they should bring into the question? One thing I know for certain is that I don't want to be dealing with this potential distraction/error on October 1.
