The coastal state of Louiseville boasts of an average life expectancy of 77 years which is significantly higher than that of the hinterland state of Missouville, a state which is a predominantly agrarian economy. The environmental and external health factors positively affecting the human life-span are found in great abundance in the coastal areas. Therefore, if a newly married couple want to start their family with the hope that their offspring have a longer life-expectancy, they should prefer Louiseville to Missouville.

Which of the following most seriously weakens the argument?

A.A person's life span is usually determined by the combined impact of shared genetics and environmental factors.
B.Currently an agrarian economy, Louiseville is on its way to fast becoming an industrial state with all the side-effects of industrialization that negatively impact the mentioned environmental factors.
C.Children born outside Missouville to couples originally from Missouville have displayed no difference in life-span from the children born in Missouville.
D.A few of the children to people originally from Louiseville but who moved out before their children were born, displayed a significantly longer life span than some of the children to couples who stayed within Louiseville.
E.Migrating poses serious economic problems for couples who are setting up homes and starting families away from their native place.

Hello,

I agree with Option B. But Option A clearly states that the life expectancy is dependent on both genes and environmental factors. The conclusion says, If a couple wants their kids to have longer life expectancy, then they should move to Louiseville. But as per A, if the parents already have bad genes, the conclusion weakens, right? Can you please help me understand why it is wrong?

Hi Alok,

The key is in the usage of the word "longer". Longer life expectancy than what? Than if they didn't move to Louiseville. In both cases, the genes are a fixed factor and can't be changed. So even if the kid is unfortunate on that front, (s)he would still have a longer life by moving to Louiseville as opposed to not moving. This is why we would eliminate A.

Answer Option 'A' is actually strengthening the Argument. Don't you think so ?
Conclusion is talking about +ve Effects of Environmental Factors and so does AO-A. Though 'A' adds genetics factors as well, but in any case it's strengthening the Conclusion. Hope it Helps

180-deg: This actually strengthens the argument!

Genetics : Neutral. Doesn't matter where they live, genes will be the same.
Environmental factors: If Louiseville has better environmental factors then they should definitely move there since option (A) is saying it will help!

B.Currently an agrarian economy, Louiseville is on its way to fast becoming an industrial state with all the side-effects of industrialization that negatively impact the mentioned environmental factors.

If environmental factors play a role in prolonging life as per the original argument, and if those same factors are negatively changing, then it's reasonable to say that this is weakening the conclusion!

C.Children born outside Missouville to couples originally from Missouville have displayed no difference in life-span from the children born in Missouville.

Irrelevant. We don't care about children born elsewhere other than Louiseville & Missouville.

D.A few of the children to people originally from Louiseville but who moved out before their children were born, displayed a significantly longer life span than some of the children to couples who stayed within Louiseville.

Irrelevant. We are discussing the children of people from Moissouville not Louiseville.

E.Migrating poses serious economic problems for couples who are setting up homes and starting families away from their native place.

Irrelevant.

The two factors affecting life-span according to the original passage are Environmental Factors & External health factors, whether there is a third factor is outside the scope of discussion.
