A person is considered obese if her BMI i.e. Body Mass Index, a ratio of a person’s weight to square of her height, exceeds a certain number. In 1990, the average BMI of the population was just below the threshold level for obesity. However, in a recent survey conducted, it was found that the average weight was 10% more than that of the population in 1990. Given that there has not been any increase in average height of the population since 1990, the obesity levels in the country must have increased.


Which of the following, if true, would cast the strongest doubt on the conclusion drawn above?

  • a)
    In another survey conducted, it was found that the average fat consumption by individuals in the country has decreased.

  • b)
    A major criterion for selecting participants in the survey was the willingness of the participants to actively participate in the survey.

  • c)
    The population of country has increased by more than 10% since 1990.

  • d)
    Obese people have a shorter life span than other people.

  • e)
    All the participants in the survey were taller than an average citizen of the country

A person is considered obese if her BMI i.e. Body Mass Index, a ratio ...
It's a comparison type and generalisation kind CR Argument.
so the natural assumptions just after reading the passage are

what happened in the past is similar to present day survey.that means the measurement criteria has not changed.

survey word is used ,so another assumption will be

The survey sample is representative in both conditions.

so let's go to the choices
A says about fat ,what's the outcome do you know.we are sure it .ans is no I am not sure.so out

B says all the participants are having heigher height than the rest and the conclusion says the BMI MUST HAVE INCREASED IN PASSAGE.AND THIS COUNTERS THE CLAIM,bkz weight increased by 10% and heights of the sample space also increased above the average, but not given how much.and this is point that make the conclusion doubtful bkz the conclusion uses the word MUST increase.a slightest doubt creating but non extensive answer choice can be good strengthener or weakner.

c says nonsense.ha ha
d says obese have short life span so what do with bmi

e says cunning thing :it says major criteria for selection is willingness,now the question is who will have the willingness,and for godsake don't extrapolate to think that only higher weight to lower height people will agree to participate bla bla bla..
Answer is B,based the assumption that the survey sample is representative or its called the specific to generic assumption CR type.

Eating fish and other foods rich in omega-3 fatty acids could help people maintain healthy brains as they age as well as protect their hearts, new research suggests. Per this research, participants with low levels of omega-3 fatty acids in their blood had slightly smaller brains and scored lower on memory and cognitive tests than people with higher blood levels of omega-3s.The researchers then looked at and ranked the level of omega-3 fatty acids in the participants blood. People who scored in the bottom 25% in omega-3 fatty acid levels were compared with the rest of the study participants. Researchers found that those who had the lowest level of omega-3 fatty acid levels in their blood had lower brain gray matter volume compared with those with higher levels.Gray matter volume is crucial to brain health. When it remains higher, brain health is being maintained. Decrease in gray matter volume indicates that brain cells are shrinking. The findings showed that consumption of baked or broiled fish on a weekly basis was positively associated with retention of gray matter volume in several areas of the brain. In fact the greater hippocampal, posterior cingulate, and orbital frontal cortex volumes obtained by optimal fish consumption led to reduced risk of contracting MCI or Alzheimers by almost five-fold.The most recent U.S. dietary guidelinesreleased last yearrecommend at least two servings of seafood a week. Some doctors and diet experts recommend that patients consume fish three times a week or take fish-oil supplements so they get enough omega-3 fatty acids to obtain health benefits.The passage suggests the following about diet and gray matter volume
