Official Explanation

Question #1
Assume that any increase of 5% or more from one century to the next in the amount of a given food consumed by Barras residents is due primarily to a corresponding increase in imports of that food into Barras from other villages. Given this assumption and the information provided, for each of the following, select Yes if it describes a food likely imported by Barras during times of increased food consumption. Otherwise select No.

The passage on the Village Sites tab says Agna was not established until around AD 800. Therefore, Barras could not have imported meat from Agna in the AD 600s.

The table on the Food Consumption tab shows that per-capita amount of meat consumed in Barras more than doubled from 70 pounds per 4-person family in the AD 800s to 172 pounds per 4-person family in the AD 900s. The passage on the Village Sites tab suggests that Agna and Cussaia were likely the only villages trading with Barras. It also says that Agna traded meat to Barras and suggests that Cussaia probably did not. Therefore, given the assumption that any increase of 5% or more in the amount of a given food consumed by Barras's residents was primarily the result of a corresponding increase in imports of that food into Barras from other villages, Barras probably imported meat from Agna during the AD 900s.

The preceding shows that the period from the AD 600s through the AD 700s was indeed a time of increased food consumption (particularly with respect to grain), and the passage on the Village Sites tab indicates that Agna and Cussaia were likely the only villages trading with Barras. Agna did not exist until around AD 800, but Cussaia predated Agna and depended heavily on raising grain crops, which it could have exported to Barras. Given the assumption that any increase of 5% or more in the amount of a given food consumed by Barras's residents was primarily the result of a corresponding increase in imports of that food into Barras from other villages—Barras likely imported grain from Cussaia during the AD 700s.

Question #2
For each of the following, select Yes if the statement is separately supported by the passage and separately supported by each of the two tables. Otherwise select No.

Although the passage on the Village Sites tab says that Barras's population increased from the AD 600s to the AD 1200s, and the tables on the Food Variety and Food Consumption tabs both imply that Barras was inhabited throughout this period, neither table alone says or implies anything about whether Barras's population increased or decreased.

The passage says that Agna grew no grain, but the table on the Food Variety tab does not mention Agna at all, and the table on the Food Consumption tab does not mention grain at all.

The passage on the Village Sites tab supports the statement that Cussaia traded directly only with Barras, but neither table mentions Cussaia at all.

Hi,

Please use table 2. The question is demanding us to assume 5% or more of a given food item. From AD 600 to AD 700, the proportion of grains increased from 10% to 15%. Here the overall consumption of a given food should be considered and not the overall food consumption increase.

Hope this helps.

Thanks,

An additional question that I am inserting here due to the fact that the tables are already here:

and the correct is in a square, mine are in the circle

I think it asks that the facts be distinctly shown by both the passage and tables, therefore the questions have been answered as no in each case.

Had the question been, Was seafood a major chunk of the diet plan for Barras? then the answer would have been yes.

Again a question regarding the "grains from cassia from 600 to 700"

The question states: "Assume that any increase of 5% or more from one century to the next in the AMOUNT..."

Tab 2 gives us information about the "percentages, by estimated weight, of dietary items consumed per person"
We see an increase of 5% of grain. However, tab 2 gives us only information about the composition of the dietary in each century and not about the consumed amount. Isn't it possible that the overall consumed amount was reduced and the amount of grain consumption did not increase by 5%? Therefore, the event in the question stem would not hold in this scenario.

Am I flawed in my thinking process?

1) Refer Village Site: Barras: "Its population increased from an average of 100 residents in the AD 600s to 400 residents in the AD 1000s to 600 residents in the AD 1200S"
So from above statement answer for question 1 is YES.

2) Refer Village Site: Agna: "Agna grew no grain."
So from above statement answer for question 2 is YES.

3) Refer Village Site: Cussaia: "It taded directlly only with Barras"
So from above statement answer for question 2 is YES.

Monthly meat consumption for a family of 4 in AD 1000 = 160 lb
Residents in AD 1000 = 400, ~100 families of 4.
100 * 160 lb = 16,000

By a similar logic, in AD 1200 pounds consumed would be 24,000

Assuming a linear increase, the number in AD 1100 would BE 20,000 and the average in the 1000s would be 18,000.

Can you assume a linear increase? not sure, but it's definitely > 16,000

Number of residents in Baras in 1000 ADs =400.

=> on average for a 4 person family, we have 100 families.

Now we are given that 160 lbs is the average meat consumption of a 4 person family in 1000 ADs.

Thus, Average total meat consumption = 100 * 160=16000. Hence, Answer is C.

Question no. 3 says we need to select yes ONLY IF we have the below information supported by each of the three tabs.

But, you can see that it is not a valid case for any of the three points provided. Hence, Answer is No for all.

No, we are not justifying the answer somehow. This is how GMAC works. GMAC people know that many people are going to miss the word each and gonna mark the wrong answer.

The main reason why people select no for this question is because they are not sure whether Cussaia grew grain or not. Now there are 2 things to notice:
1. Assumption - any 5% increase in food is likely due to an increase in import - that implies any food whose consumption has increased is not self grown.
2. If grain's consumption is increased then it must have been imported from either Agna or Cussia. if you think you cannot tell from whom import has been made then you would answer this as NO. But in the first table we are told that Agna grew no grain.

Hence this information - Agna grew no grain -- combined with the specified assumption tells us that import has been made from Cussia.

For the 2nd set of questions that someone posted about:

The question asks: which statements are supported by the passage AND SEPARATELY supported by EACH of the two tables.

The passage clearly supports the 3 statements, so "yes", BUT the tables on the subsequent 2 tabs do NOT mention anything about the statements. Therefore, all 3 statements are "No".
