Critical Reasoning

While 65% of the eligible voters who were recently polled favor Perkins over Samuels in the coming election, the results of that poll are dubious because it was not based on a representative sample. Given that Perkins predominately advocates the interests of the upper-middle class and that the survey was conducted at high-priced shopping malls, it is quite probably that Perkin's supporters were overrepresented.

Which one of the following statements most accurately expresses the main conclusion of the argument?

A) The poll was intentionally designed to favor Perkins over Samuels.

B) Samuel's supporters believe that they were probably not adequately represented in the poll.

C) The poll's results probably do not accurately represent the opinions of the voters in the coming election.

D) Samuels is quite likely to have a good chance of winning the coming election.

E) Those who designed the poll should have considered more carefully where to conduct the survey.

imo: c

Which one of the following statements most accurately expresses the main conclusion of the argument?

A) The poll was intentionally designed to favor Perkins over Samuels.

We cannot infer from argument that poll was INTENTIONALLY designed favoring Perkins - its quite possible that poll managers made a mistake while deciding the sampling...we are not sure.

B) Samuel's supporters believe that they were probably not adequately represented in the poll.

Author gives his opinion that Samuel's supporters not properly represented - he does not give any insight whether Samuel's supporters hv the same opinion.

C) The poll's results probably do not accurately represent the opinions of the voters in the coming election.

This appears correct. Author has used 'dubious' - he does not believe in the survey result.

D) Samuels is quite likely to have a good chance of winning the coming election.

Survey focused only on 2 candidates - what if another candidate takes a decision to stand in the coming election? In such case, we can't say what is true in a survey will be true in the actual election as well.

E) Those who designed the poll should have considered more carefully where to conduct the survey.

Author is not being didactic - he mentioned his point of view, but refrained from giving ideas about how & where to conduct the survey.
