A recent study has revealed, through meticulous research, a link between the harmful hydrocarbons in air pollutants and the IQ test scores of children. The research involved measuring the quality of air that pregnant women breathed during the third trimester of pregnancy, and then following the children born from that pregnancy until an IQ test could be administered. Many external factors were taken into consideration, such as the mother's IQ and the family's home environment with regards to intellectual development. Health officials, having studied this information, plan to tackle the phenomenon by increasing public awareness on the matter through campaigns aimed at warning parents-to-be.

In the argument, the two portions in boldface play which of the following roles?

A) The first associates a cause with an effect; the second demonstrates the reasoning behind the formation of such an association.
B) The first is a relationship contradicted by the conclusion; the second is factual information that supports that conclusion.
C) The first is the result of an analysis; the second weakens the possibility of doubt with regards to the accuracy of that analysis.
D) The first is a correlation between two entities; the second is evidence that directly strengthens the existence of that correlation.
E) The first offers a logical connection between two factors; the second indicates a possible flaw in the credibility of that connection.

The opening line mentions that the study revealed something. Hence down to C and D.

C) The first is the result of an analysis; the second weakens the possibility of doubt with regards to the accuracy of that analysis.
D) The first is a correlation between two entities; the second is evidence that directly strengthens the existence of that correlation.

The first BF is the result of a study and the second BF mentions that various factors were considered and then a conclusion was obtained. Hence C suits more.

The second BF does not provide any evidence (as per stem) to offer direct support to the result obtained.

 Studies reveal : Correlation between HC -------> IQ of Children.2nd Bold face : Other external factors which could affect the IQ of Children was taken into consideration.

Have have the 2nd bold face ( Control Condition ) so that we can strengthen the result of the survey that a Correlation exists between HC & IQ of Children only, and the external factors do not affect or weaken the conclusion ( Result of the analysis of the survey ) the IQ of Children.

option a can be right way eliminated as the second bold face is not 'the reasoning'

option b says 'contradicted'. There is no contradiction in the argument. Hence wrong.

option d says the second part is a evidence. The second part is not a fact. hence ruled out.

option e talks about a flaw . There is no flaw in the relationship given or the argument. Hence wrong.

Left option c is correct and explains the roles of the two bold face correctly.
