Argument Analysis :-

1. The argument says that Fast-food restaurants make up 45 percent of all restaurants in Cantaria.
2. Youth is a main consumer at these restaurants.
3. The average age is rising(people are moving towards old age).
4. Therefore number of restaurants are likely to decrease.

Which of the following, if true, most seriously weakens the argument?

(A) Fast-food restaurants in Canatria are getting bigger, so each one can serve more customers.
Does not matter if they become bigger. The problem will still not be solved, if the average age is rising. Irrelevant.

(B) Some older people eat at fast-food restaurants more frequently than the average young person.
This is against the premise given in the question that people tend to be young at Fast food restaurants. We cannot challenge the question stimuli. Irrelevant.

(C) Many people who rarely eat in fast-food restaurants nevertheless eat regularly in restaurants.
So what!! We are talking about how to tackle average age rising scenario. Irrelevant.

(D) The overall population of Canatria is growing steadily.
Sounds good. The overall population is growing steadily means Canatria is having a influx of newborn.They will become young one day. Hence will eat at these restaurants.
Weakens the conclusion. :)


(E) As the population of Canatria gets older, more people are eating at home.
This will strengthen the argument. If this is the case, restaurants are likely to decrease.

Detangle the argument in your own words:

There are CURRENTLY 45% of fast-food restaurants in Cantaria that normally cater to young people.
The author then concludes that because average age of the population is rising, THERE WILL be fewer of these restaurants.

The author is making a prediction about the future. Most importantly, he assumes NOTHING else is changing between now and then. i.e. The population of young people is NOT increasing.
That is what answer choice C highlights. This type of assumption regarding predictions is very typical in CR - pay attention.

(A) Fast-food restaurants in Canatria are getting bigger, so each one can serve more customers. (It means the number is not decreasing so its wrong)

(B) Some older people eat at fast-food restaurants more frequently than the average young person. (Its breaking our argument)

(C) Many people who rarely eat in fast-food restaurants nevertheless eat regularly in restaurants. ( not our concern ) wrong

(D) The overall population of Canatria is growing steadily. (Yes correct)

(E) As the population of Canatria gets older, more people are eating at home.( Thats not our concern, Are they eating at fast food restaurant or not. That is our concern( Wrong)

Argument = Older people eat less at fast food restaurants + Avg Canatria age increasing -> # fast food goes down

(A) Fast-food restaurants in Canatria are getting bigger, so each one can serve more customers. out of scope; if anything this strengthens conclusion (more ppl can fit in a restaurant, less restaurants are needed )

(B) Some older people eat at fast-food restaurants more frequently than the average young person. this one is tricky! makes it seem like bc there's older people that eat at restaurants more frequently than the avg young person, it contradicts a premise BUT you have to remember this doesn't mean that the AVG old person doesn't eat as frequently as the AVG young person, just like there can be genius high schoolers smarter than the avg college student but it doesn't mean the avg high school student is smarter than the avg college student

(C) Many people who rarely eat in fast-food restaurants nevertheless eat regularly in restaurants. out of scope

(D) The overall population of Canatria is growing steadily. even if the avg age goes down, if there's same or more young people than the amt of restaurants may not go down

(E) As the population of Canatria gets older, more people are eating at home. wrong, if anything this strengthens. more old people eating at home -> less fast food restaurants
