Which state produced the most citrus fruit in 2010: florida, california, or texas?

which advanced search would likely produce the best research material?
2010 + agricultural production by state
orange + grapefruit + 2010 + production
florida + california + texas + citrus fruit
citrus production + variety + state + 2010

I would contend that the right answer is the D) citrus production + variety + state + 2010.

Explanation: Just to elaborate a little on the answer, it can be added that the other three options can be discarded, since they either miss information or are not specific enough. You need to look for citrus fruits produced in 2010 in three states. Option A looks for agricultural production in general, not for citrus fruits specifically. Option B looks for orange and grapefruit production only, but citrus fruits also include lemons, mandarins, and so on. Option C does not include the year of production. Therefore, the advanced search that would likely produce the best research material is the D, since it looks for citrus production, by variety, by state, and by year.
