Crack CRs Part-3

[Dream_GMAT]

5-DNA fingerprinting” is a recently-introduced biochemical procedure that uses a pattern derived from a person’s genetic material to match a suspect’s genetic material against that of a specimen from a crime scene. Proponents have claimed astronomically high odds against obtaining a match by chance alone. These odds are based on an assumption that there is independence between the different characteristics represented by a single pattern.
Which one of the following, if true, casts the most doubt on the claim of the proponents of DNA fingerprinting?
(A) The large amount of genetic material that people share with all other people and with other animals is not included in the DNA fingerprinting procedure.
(B) There is generally accepted theoretical basis for interpreting the patterns produced by the procedure.
(C) In the whole population there are various different subgroups, within each of which certain sets of genetic characteristics are shared.
(D) The skill required of laboratory technicians performing the DNA fingerprinting procedure is not extraordinary.
(E) In the investigation of certain genetic diseases, the techniques used in DNA fingerprinting have traced the transmission of the diseases among the living members of very large families.

6-The public in the United States has in the past been conditioned to support a substantial defense budget by the threat of confrontation with the Eastern bloc. Now that that threat is dissolving, along with the Eastern bloc itself, it is doubtful whether the public can be persuaded to support an adequate defense budget.
Which one of the following indicates a weakness in the position expressed above?
(A) It presupposes that public opinion can be manipulated indefinitely, without the public’s becoming aware of that manipulation.
(B) It refers to past and present events that do not have a causal connection with public support of the budget.
(C) It assumes as fact what it seeks to establish by reasoning.
(D) It fails to give any reason for the judgment it reaches.
(E) It hinges on the term “adequate,” the precise meaning of which requires reevaluation in the new context.

OAs after discussions !!!

wow~ what a difficult Qs
i think first one is A
and second one is E

where did you get these question?

[MCapri]

IMO A and C

@Dream_GMAT. u will get more explanations if u post the CR's in the CR thread

[Dream_GMAT]

Some more tries guys...!!
@MCapri i will take care of ur suggestion !!!

[KillGmat]

According to me,the answers are A and E

Q1)

proponents claim-high odds against obtaining a match by chance

To support their claim they state that

there is independence between the different characteristics represented by a single pattern.

but if The large amount of genetic material that people share with all other people and with other animals is not included in the DNA fingerprinting procedure.

then cops wont be able to catch many criminals since their genetic records are not available in fingerprinting procedure.

We do not know how much this "adequate" is.
If it is less then people might very well ignore it.
It if it is "substantial" then people might object to it as argument says.

Guys thanks for the reasons.OAs are C and E.
Can someone please have a fresh look at first question?Any other reasoning behind the answer being C.?

It should be C for the 1st question. Reached C thru POE and it fits the bill as it is the only choice that attacks the proponents assumption that
These odds are based on an assumption that there is independence between the different characteristics represented by a single pattern.

The keyword is there is independence between the different characteristics.

In ans choice C it clearly states that "certain sets of genetic characteristics are shared". So if this is true it implies that the chances of fingerprints matching for two individuals in a same group is high.
