OEFor each choice, carefully find the row(s)/column(s) that fit the description, and sum all table entries that apply.
(A) More than $10 billion GDP (the top three rows) and a population of less than 20 million (the three columns on right, before the subtotal column): 0 + 0 + 0 + 1 + 1 + 0 + 3 + 3 + 3 = 11.
(B) Less than $20 billion GDP (the bottom two rows above the subtotal row) and a population of more than 10 million (the three columns on left): 1 + 3 + 3 + 0 + 0 + 7 = 14.
(C) More than $20 billion GDP (the entire top two rows): 5 + 10 = 15.
(D) Less than $100 billion GDP (the bottom three rows above the subtotal row) and a population of less than 10 million (the two columns on the right before the subtotal column): 1 + 0 + 3 + 3 + 8 + 7 = 22.
(E) Less than $100 billion GDP (the bottom three rows above the subtotal row) and a population between 10–50 million (the second and third columns): 7 + 1 + 3 + 3 + 0 + 7 = 21. Greatest.
Choice (D), 22, is the greatest.
