In order to protect its budding printer industry, Country X's government plans to ban all printer imports. Several thousand concerned citizens protested, claiming that such a ban will inevitably result in a sharp rise in the prices of printer retail prices.
Which of the following can be most properly inferred from the passage?
A. Implementing the government's plan will result in a drop of sales of printers in Country X.
B. The prices of imported printers are very competitive in relation to those of the printers manufactured in Country X.
C. If the government does not reverse its plan, it will lose the support of voters.
D. Implementing the government's plan will leave citizens no choice but to illegally import printers.
E. The government's plan will lead to a severe shortage of printers in Country X.
Only answer B is even plausible as a right answer here, but it's not a proper inference from the passage, for two important reasons.
For one, all we know is that "several thousand people claim" that prices will go up (and this is several thousand people in a country that could have a population of millions). Are these "several thousand people" right? We have no evidence one way or the other. The passage only tells us what a few thousand people claim is true. When you only know that some people claim prices will rise, you can't correctly infer that prices actually will rise.
But even if we did know printer prices will rise, I still don't follow why we'd infer B is true. It's easy to imagine a situation with two companies, domestic printer manufacturer D, and a foreign manufacturer F where right now, F's prices are not competitive, so most or all people are presumably buying D's printers. But when F is no longer in the market because of an import ban, D now has an effective monopoly and can freely raise its prices, something it couldn't do before because raising prices would then have made F's prices competitive and F would have cut into D's sales. So I'm not sure why answer B is a correct inference from the passage -- yes, it certainly could be true, but when we're asked to draw an inference, we're asked to find something stronger than that.
