A. is incorrect, since we only have info about the total consumption of poultry/fish. What if two families ate something like 2 tons of chicken and 1000 families ate something like 2 pounds of fish every day?

B. the passage does not provide info about the quantities of fish/poultry consumed, it just points out their respective gains.

C. is correct. Look at it mathematically:
population in 2000 = x
population in 2005 = 106% *x

poultry in 2000 = y
poultry in 2005 = 109% *y

per capita poultry consumption in 2000 = y/x
per capita poultry consumption in 2005 = 109%y/106%x = y/x * 109/106 > y/x

D. no info to establish this

E. profits are not discussed here. Indeed, the amount sold was greater, but what if costs increased significantly, say by 20%? Then the profits go down...

109% consumption of poultry products/ 106 %population > consumption of poultry products/population = 1

So, choice C is the correct one.

A)For new arrivals to Eastland between 2000 and 2005, fish was less likely to be a major part of families’ diet than was poultry.
Nowhere it is mentioned that only the new arrivals were responsible for the increase in fish consumption.
It could be that the whole of increased population was responsible for the increase.

B)In 2005, the residents of Eastland consumed twice as much poultry as fish.
Yes, the total consumption increased but no where it is mentioned that the residents consumed it.
They could be buying fish to simply feed the bear, dog or just make cod liver oil from that.

C)The per capita consumption of poultry in Eastland was higher in 2005 than it was in 2000.
CORRECT.

D)Between 2000 and 2005, both fish and poultry products were a regular part of the diet of a significant proportion of Eastland residents.
Too many absolute modifiers here:
1) "regular part of the diet" Maybe they use it only during gatherings and functions.
2) "significant proportion" Maybe only a insignificant proportion consume a lot of fish and poultry?

E)Between 2000 and 2005, the profits of wholesale distributors of poultry products increased at a greater rate than did the profits of wholesale distributors of fish.
No mention about "profits". Incorrect

This is a very good practice question.

According to the stimulus,

Total fish comsumption = 4.5 percent increase
Total consumption of poultry products = + 9.0 % increase
Total Population = 6 % increase.

Since all the values given in the stimulus are percent increases, and we do not know the base value in 2000, we can eliminate B and D. E is irrelevant because profit is not mentioned anywhere. We can eliminate A as it requires us to assume that most of the population increase was due to the new arrivals.

C is the correct answer and can be proven from the information in the stimulus.

at first i thought it was D, but looking a it again we can see that the % increase in population is lower than the % increase in the consumption of poultry so we should see an increase in poultry consumption per capita.
Also, the stimulus only talks about percentages never actual numbers so our answer should reflect only based on percentages not actual figures.

Which of the following, if true, can one infer based on the statements above?

A) For new arrivals to Eastland between 2000 and 2005, fish was less likely to be a major part of families’ diet than was poultry. Though percentage increase in Eastland's population (6%) is higher than percentage increase in fish consumption (4.5%), it is possible that some of existing population have reduced consumption of fish despite higher/same consumption of fish from new entrants in Eastland. Incorrect

B) In 2005, the residents of Eastland consumed twice as much poultry as fish.nothing in the stimulus state about relative amount of fish and poultry consumption. It states about percent increase in consumption which does not translate directly into amount. Incorrect

C) The per capita consumption of poultry in Eastland was higher in 2005 than it was in 2000. Suppose in year 2000, consumption of poultary was X while population was Y, thus percapita consumption was Y/X. Now in 2005 , Poultry consumption increased by 9 percent, thus amount poultry consumption was 1.09 X. Similarly, population increased by 6%, therefore new population is 1.06 Y. Combining these two data, in 2005, per capita consumption is 1.09X/1.06 Y > X/Y (IN 2000). IMO Correct answer

D) Between 2000 and 2005, both fish and poultry products were a regular part of the diet of a significant proportion of Eastland residents.nothing in the stimulus states this fact. Incorrect

E) Between 2000 and 2005, the profits of wholesale distributors of poultry products increased at a greater rate than did the profits of wholesale distributors of fish.out of scope. stimulus doesn't states profit anywhere.Incorect

C
Total consumption of poultry increase 9% > population increase 6%
If you divide two number, total consumption/ population = per capita consumption has to increase since 9% > 6%

Superb explanation DanaJ!

Really helped to crack the inference question.

This is how maths is used in inference CR.

D)Between 2000 and 2005, both fish and poultry products were a regular part of the diet of a significant proportion of Eastland residents.
E)Between 2000 and 2005, the profits of wholesale distributors of poultry products increased at a greater rate than did the profits of wholesale distributors of fish.

Prethink inference-The per capita consumption of poultry was greater in 2005 than in 2005-109/106 in 2005 against 100/100 in 2000. only C matches this hence C is correct

other options
A)For new arrivals to Eastland between 2000 and 2005, fish was less likely to be a major part of families’ diet than was poultry-Likeliness/preference is not an issue here.It may be true but not always have to be true.
B)In 2005, the residents of Eastland consumed twice as much poultry as fish-Same as A
C)Between 2000 and 2005, both fish and poultry products were a regular part of the diet of a significant proportion of Eastland residents-Do not always have to be true same as option A
E)Between 2000 and 2005, the profits of wholesale distributors of poultry products increased at a greater rate than did the profits of wholesale distributors of fish-Profits is not the issue here hence out of scope

suppose we have 1,000,000 people
and we have 1 fish/person and 0.5 chicken per person. -> I agree, not a good way to look at it, but good to understand why C is bad.
we have 1 fish and 0.5 chicken per capita. 500k chicken

population increased by 6% we have 1,060,000 people. chicken 9% increase. 545,000 now.
545000/1060000 = 545/1050 slightly more than 1/2

C works fine.

IMO C

a) we dont know that for sure. what if existing people stopped eating fish and started eating poultry.

b) we cannot infer anything from their amounts.

c) This is true, the per capita consumption of poultry products increased.

d) we cannot infer this.

e) profits is out of problem's scope.

OFFICIAL EXPLANATION

This argument includes statistics about the relative increases in the consumption of fish and poultry in Eastland, respectively, as well as the population growth in Eastland during the same period. Because we are given only information about the percentage increases of fish consumption, poultry consumption, and the population of Eastland, we should look for an inference that is closely tied to percentage information and not actual numbers.
(A) Though poultry consumption increased at a higher rate than fish consumption, there is no way to determine if this is due to the dietary habits of the new arrivals in Eastland. It is also possible that consumption among long- time residents of Eastland increased at a dramatically higher rate.
(B) We are given information about the relative rate of increases, not the actual amounts of poultry or fish consumed. As a result, there is no way to know if this statement is true.
(C) CORRECT. As we are given that the population of Eastland increased by 6 percent, and the total consumption of poultry increased by 9 percent in the same period, then it must be the case that the per capita, or average, consumption of poultry rose from 2000 to 2005. For example, let's say that the population of Eastland increased by 6 percent from 1000 to 1060 people, while the consumption of poultry increased by 9 percent from 100 to 109 units. The per capita consumption in 2000 would have been exactly 100/1000 while the per capita consumption in 2005 would have been 109/1060, a slightly greater value.
(D) There is no way to determine if fish or poultry comprised a regular portion of the diets of “a significant proportion” of Eastland residents, as the cited percentage increases may have come from very low original amounts.
(E) There are many variables in determining the profits of wholesale distributors aside from the total consumption of poultry or fish. For example, labor costs, transport, and procurement could all impact the profitability of distribution companies. It is not possible to determine that the profitability of these companies maintained the same relationship as the total consumption of poultry and fish.
