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,
Ari

Obviously, Anyone can provide them the grain, the point is Barras imported as the consumtion was up the target 5% to trigger that assumption

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?

Your reasoning is prfectly OK, but the trick here is how to use the 2 tables together to solve the problem. Notice that seafood consumption percentage remains the same from 600s to700s (65%), and its actual consumed amount arised from 240 to 250 (a bit more). In other words, the total amout of food consume must have increased too. So, grain consumption actually has in increase of at least 50% (from 10% of x to 15% of y, while y is bigger than x).
