The device, for instance, can be set to 30 one’s favorite flavor.
答案：(B) release
release 在此是「釋放、散發」：這套裝置可以設定成釋放出使用者最喜歡的味道；impress（使印象深刻）、bother（困擾）、attract（吸引）的受詞都不會是 flavor。
答對率 36%。
release 你大概只記得「發行」（release a new album）與「釋放（人）」。用在氣味、氣體、能量上時，它是「散發、釋出」：Plants release oxygen.（植物釋出氧氣）。
前一句說這套裝置用的是 scent bottles（香氛瓶），下一句說 80% of the participants were fooled by the smell（八成受試者被氣味騙過）——前後都在講味道，裝置能做的當然是釋放氣味。
impress、bother、attract 的受詞都該是人，不會是 flavor，從搭配就能全部刪掉。
release a scent／gas（散發氣味／氣體）、release a film（電影上映）、be released from（自…獲釋）。
Researchers from a university in Japan have developed "diet-glasses" that play tricks with one's perception of food, which could be helpful to people on a diet.
A camera and a viewing system are built 26 these glasses. As the wearer brings the food toward their mouth, the camera captures an image of the food. It replays the image back through the glasses after processing it on an attached computer. The size of the food they are about to eat is magnified while 27 of their hand remains normal. Their brain is 28 tricked into thinking they are eating more than they really are. The study showed that participants who wore the glasses ate 9.3 less than those who did not wear them.
The team has also developed a special device which uses scent bottles and visual trickery to make the wearers of these glasses think that the plain snack they are eating is 29 than it actually is. The device, for instance, can be set to 30 one's favorite flavor. Recent experiments with this device showed that 80 of the participants were fooled by the smell. For example, some participants thought that they were eating a chocolate snack, but in fact they were not.
