Telling a yellow taxi and abinoculars apart is so easy that most people could do it without a secondthought. However, it is not so for an artificial intelligence: if you turn thetaxi upside down, it sees Binoculars.
This is just one of dozensof examples that show AI is a lot worse at identifying objects by si
ght than manypeople realize. The examples, collected by Anh Nguyen at Auburn University inAlabama, raise concerns about the real-world ability of AI image recognitionsystems.
Nguyen and his colleaguestook images of common objects from the Internet and rotated  and changed the position of the objects in the pictures. Theyfound this was enough to confuse several AI systems, including Google’s. In onecase, a school bus that was correctly identified in the original image wasmisidentified as a lunch box when upside down in the road. It shows thesesystems aren’t as intelligent as many people think they are.
Nguyen worries what couldhappen in real-world situations. For example, it makes sense for a driverlesscar with AI system to avoid an object it can’t recognize. But if the car stopunexpectedly because it thinks a Coke can is a fire fighting truck, this couldbe as dangerous as thinking a fire fighting truck is a Coke can. This is onereason why driverless cars will need several sensors  to provide moreinformation, says Nguyen.
His team has beendiscovering these problems for the past few years, but nobody knows how to fixthem. The biggest problem to progress is that when an AI looks at an image, itcan
’t extract  rules that would help itidentify a similar one next time – such as the rule that horses have four legs.”To reach a human level of reasoning, we need a way to extract rules fromimages,” says Nguyen.
（1）In paragraph 1, the example of a taxi is used to .
A . raise people’s concerns about the safety of AI system.B . prove that human beings are much smarter than AI systems.C . introduce the topic concerning AI’s image recognition ability.D . show a taxi can have different forms when seen from different views.
（2）We can learn from the last paragraph that .
A . AI can’t tell a horse and a car apart because they both have four legs.B . AI can’t reason like human, which is the biggest challenge.C . AI doesn’t have the ability to tell things apart that look similar.D . AI can’t identify images from earlier experiences.
