Residents of Milatia are known for their longevity. Nutritionists maintain that the Milatians can attribute their increased lifespans to their diets. In addition to consuming a diet full of leafy greens, they also have a low intake of saturated fats, which have been implicated in heart disease and atherosclerosis. Therefore, if one wants to have increased longevity, he or she should follow a Milatia based diet.

Which one of the following is an assumption on which the argument depends?
A. Other aspects of the Militians’ lifestyle do not affect the observed trend of longevity in Milatia.
B. Adopting another people’s eating habits will, in of itself, not confer the same advantages, unless a person incorporates exercise into his or her life.
C. The Milatian lifespan has a relatively uniform distribution, with very few dying young from natural causes.
D. Milatians are the only people in whom there is a perceived link between diet and longevity.
E. All Milatians are known to have a lifespans that are above average.


Found this one interesting. Please post your answer with explanations.

D. Milatians are the only people in whom there is a perceived link between diet and longevity.
E. All Milatians are known to have a lifespans that are above average.

Conclusion has Causal relationship- Milatia based diet leads to longevity.

Assumption- 1. Cause happens before effect.
2. No other reason for longevity
3. Longevity does not lead to Milatia based diet

Hence ans is A matches 2. above IE Negate other reason for longevity .

Hey guys.. I chose option A but I have a little apprehension about choice C as well.
C. The Milatian lifespan has a relatively uniform distribution, with very few dying young from natural causes
Can someone please elaborate why this option is wrong... My explanation is below and I dont fin dit convincing enough for myself.
The conclusion relates diet of Milatians and their longevity. If we negate C, then there are many people who die from natural causes. This fact does not help in refuting the effect of diet on logevity. Those who remain might have long life span owing to good diet. hence the conclusion does not fall apart. I rejected this option just based on this...
Some more inputs please - direct and by assumtion negation test will be helpful.

Hi ...Here is OE for option C:

If we negate (C), “…[does not] have a uniform…” it doesn’t weaken the argument. A Milatian diet is still responsible for longevity, just not for everyone.

The reasoning you have applied here is self-explanatory and really good.

Hope this helps. :-)

Strengthens the argument. But it is not a necessary assumption.
Argument still stand if we don't assume A or negate A.

Option C
Out of scope
A lead to B
A : good diet
B: longevity of the Milatia

Longevity of Milata already proven in the argument is a part of premise. We can’t doubt Longevity. Any doubt regarding longevity is out of scope.

expert please help.

Causality relation here:
if one wants to have increased longevity, he or she should follow a Milatia based diet. i.e. Militia based diet -> Increased longetivity

Possible ways for a Causality relation to hold are:

- No other possible cause for the effect
- Effect does not happen cause doesn't happen
Hope the below link helps.

In fact, referring Power CR bible will help you better understand the basics of causal relations. For me, studying and understanding Powerscore CR bible and then attempting questions helped a lot.

I feel negation should be the last weapon i.e. only when we are left with competing answers else it's very harmful to use negation technique for each option. Moreover, negating doesn't mean completely destroying an argument but rather weakening the argument.

If we negate A then we get i.e. Other aspects of the Militians’ lifestyle affects the observed trend of longevity in Milatia

This states that diet is not the only factor for the observed trend of longevity in Milatia. This indeed falls apart the causal relation.

There are indeed slight differences between strengthening an argument and assumptions,such as Strengthening will provide evidence to strengthen our conclusion but that may not be an assumption.

Hope it helps. :-)
