The United States will soon begin spot-checking all shipments of imported coffee for tainting by sandfly larvae. Any coffee found to be so tainted will be destroyed. Officials predict that the spot checks will result in the destruction of approximately 10 percent of all coffee imported into this country. Even so, the checks will miss about half of the tainted coffee sent here, since it is estimated that 20 percent of all coffee worldwide is tainted by sandfly larvae.
The information in the passage above best supports which of the following conclusions?
(A) The amount of imported coffee available for consumption in the United States may soon decrease.
(B) The United States should learn to rely more on domestically produced coffee.
(C) The United States will eventually be forced to inspect all imported coffee for tainting by sandfly larvae.
(D) Coffee producers worldwide will implement a more rigorous program of insect control.
(E) The U.S. consumer will begin paying less for imported coffee in the future.
Official Explanation
Identify the Question Type:This asks for a conclusion based on the passage, so it's an Inference question.
Untangle the Stimulus:The stimulus indicates that the US will begin spot checking imported coffee for sandfly larvae; this will likely result in 10% of the coffee being destroyed, but it will also miss about half of the tainted coffee, since 20% worldwide is tainted.
Predict the Answer:It's often impossible to predict an answer to an Inference question. Just keep the facts from the stimulus in mind and look for what must be true.
Evaluate the Choices:(A) is supported and is thus correct. Spot checks will destroy 10 percent of imported coffee, so it is logical to expect a drop in consumable imported coffee. While there is the potential to avoid this drop (e.g., increase the amount of coffee imported to offset the coffee destroyed), (A) accounts for that by saying the amount "may" soon decrease. By avoiding extreme language, (A) if deducible.
The argument is simply describes a problem, so there's no support for any particular solution such as the one in (B). There's no support for the drastic conclusion in (C) that all coffee will have to be checked. Nor is there support for (D)'s conclusion about the reaction of coffee producers. (E) is incorrect because coffee prices, like these other issues, are also unpredictable.
TAKEAWAY: In an Inference question, focus on what must be true, not just what is possibly true.
