問題詳情

請依下文回答第 31 題至第 35 題         Scientists have genetically modified mice to enable them to sniff out landmines, the explosives buried just below thesurface of the ground. They hope the GM mouse, known as MouSensor, could become a useful tool to help deal with thedangerous devices left from past wars.         Although it sounds peculiar, similar efforts have already been made. A Belgian charity uses giant African HeroRatsto sniff out the chemical explosive, TNT. Two of these rats can clear an area in less than two hours that would take twopeople two days to do. One disadvantage of the HeroRat, however, is that it needs nine months’ training before beingready for landmine detection.         Scientists wanted to improve on the HeroRat concept by creating a “supersniffer” mouse, MouSensor. They foundthat a receptor in the lab mouse’s nose is sensitive to the odor of the chemical elements in TNT and landmines. Byaltering the genes of the mouse, scientists are able to enhance the capability of its receptor 500 times stronger than before.Besides having super sniffing power, the MouSensor is cheaper to manage and easier to breed than the rats.         When the MouSensor detects the presence of a landmine, it would have some sort of a seizure and faint because ofits extreme sensitivity of the explosives. And this change of the mouse’s physical condition would trigger a chip implantedunder its skin to send a signal to a computer monitored by scientists. As a result, the location of the landmine could beidentified, and a bomb-disposal expert could go in and neutralize it. The mouse itself would be safe from the landmine,since it would be too small to trigger an explosion.
31 How would a MouSensor help to identify the location of a landmine?
(A) It would lose consciousness.
(B) It would look into a computer screen.
(C) It would hide away from the landmine.
(D) It would touch a chip implanted under its skin.
