Answer of Section 3, Question 10

When food companies seek to inflate their revenues by reducing the amount of food in each package without offering a corresponding price reduction, their marketing campaigns are often ______, claiming that the smaller versions are healthier, with fewer calories than before.

官方解說：

The word that fills the blank must describe the marketing campaigns that food companies run when they want to make more money by reducing the amount of food in each package without reducing the price of the package. According to the sentence, these campaigns claim "smaller versions are healthier, with fewer calories than before" and, in so doing, put a positive spin on the companies clearly non-altruistic motives for reducing the amount of food in each package. Of the answer choices, only "shrewd" and "artful" produce alike sentences that correctly describe such campaigns. "Uninformed" and "ignorant" also create sentences that are alike in meaning, but they fail to describe campaigns of the sort mentioned.

Thus the correct answer is shrewd and artful.
