5 out of 8 in 9 minutes not completely concentrated............mmmmm not so bad.OE for Question 8:
Please could you provide the last one OE (the contenders was B and C and I Picked B) ???
Thanks for the nice passage
In the last sentence, the author concludes that kin
recognition in tiger salamanders can be explained as a
means for preserving their own life and not as a means
for aiding their relatives’ survival. While the evidence
regarding the deadly bacterium definitely supports kin
recognition being used to preserve the individual, there
is no evidence to say that kin recognition is not used
to aid relatives’ survival. The author ignores the
possibility that kin recognition may serve to protect
oneself and one’s relatives. To weaken the claim, the
correct answer choice will show a way that a tiger
salamander would use kin recognition to protect
someone other than itself.
(A) This has no relevance to the argument. What’s
impor tant is not whether the disease af fects
cannibalistic or noncannibalistic salamanders, but
whether or not it affects kin and kin recognition.
(B) This discusses what makes salamanders
carnivorous or omnivorous, but it has no bearing on
why salamanders recognize kin. Eliminate.
(C) gives us a fact that would weaken the author’s claim.
If this were true, then kin recognition would provide a way
for salamanders to protect their offspring—thus making
kin recognition valuable beyond survival of the individual.
By protecting potential family, this weakens the author’s
claim that kin recognition is simply a self-serving device.
For the record:
(D) This answer misapplies some information from the
first paragraph about the number of offspring (part of
traditional evolutionary views). However, once again,
the number of offspring a salamander has is not
directly relevant to the reason for being able to
(E) Even if this were true, according to the passage,
they’re still immune to the one deadly bacterium that’s
mentioned. And, because that particular bacterium is
more deadly when consumed through kin, the greater
immunity to other diseases isn’t necessarily relevant to
It’s good to note for this question that the correct answer
is the only one that focuses on kin recognition, the Topic
of the argument the question asks us to weaken.
