Weaken Question Problem

by indir0ver » Sat Jul 11, 2009 8:14 am
I am close to the answers choices but just cant make out. I found whole question creating more puzzles and wasnt able to understand it. Please help.

Achaeologist: A skeleton of a north american mastodon that became extinct at the peak of the ice age was recently discovered. It contains a human-made projectile dissimilar to any found in that part of Eurasia closest to North America. Thus , since Eurasians did not settle in North America until shortly before the peak of the Ice Age, the first Eurasian settlers in North America probably came from a more distant part of Eurasia.

Which one of the following, if true, most seriously weakens the achaeologist's argument?
A) The projectile found in the mastodon does not resemble any that were used in Eurasia before or during the Ice Age.

B) The people who occupied the Eurasian area closest to North America remained nomadic throughout the Ice Age.

C) The skelelton of a bear from the same palce and time as the mastodon skeleton contains a similar projectile.

D) Other North American artifacts from the peak of the Iace Age are similar to ones from the same time found in more distant parts of Eurasia.

E)Climate conditions in North America just befor ethe Ice Age were more conducive to human habitation than were those in the part of Eurasia closest to North America at that time.

My topmost two choices are A n B.

Answer is A

Please post details as you solve this one.

to weaken the conclusion: first Eurasian settlers in North America came from a distant part of Eurasia


A. by POE. rules out any Eurasian people settling in N. America. so definitely weakens and hence correct.

B. if Eurasian people closest to N.America remained nomadic throughout, they were not the earliest settlers in N. America. doesnt affect the conclusion that first Eurasian settlers came from distant part of Eurasia

C. doesnt affect argument
D. strengthens
E. out of scope

between A and B

B says: people in Eurasia closest to North America remained nomadic throughout the Ice Age=> people from Eurasia closest to N. America could not have settled in N. America (nomadic people keep roaming and do not settle). it still keeps the possibility of people from distant part of Eurasia settling in N. America=> does not weaken our conclusion


A says it is unlikely that people from any part of Eurasia settled in N. America (as the projectile found does not resemble any projectile ever found in Eurasia)
=> if earlier settlers were not from Eurasia, they obviously could not have been from a distant part of Eurasia!.

A definitely weakens.

I am guessing this "human made projectile" is some sort of a weapon that was used to kill this mastodon.

The stimulus states that this animal became extinct right around the time of Ice age and the Eurasians who killed the mastodon, were not from any part Eurasia which was close to North America.

Choice A weakens b/c it states that this weapon does not resemble any that were used in Eurasia, which is implying that the weapon might not have come from Eurasia at all. This directly contradicts the author's hypothesis that the weapon used was from Eurasia, but some part of Eurasia which was not near North America.

-hope that helps.
