Read the following article and select the best answer. Article: An electric signal can trick a monkey's brain into believing the animal's finger has been touched. Touch something, and your brain knows. The hand sends signals to the brain to announce contact was made. But that feeling of touch may not require making actual contact, tests on monkeys now show. Zapping brain cells can fool the animal into thinking its finger has touched something. A person who has lost a limb or become paralyzed may need an artificial limb to complete everyday tasks. But such patients may not truly feel any objects they hold. The new findings point toward one day creating a sense of touch in those who use such artificial limbs. Psychologist Sliman Bensmaia of University of Chicago worked on the new tests. His team's findings appeared on October 14 in the Proceedings of the National Academy of Sciences of the United States of America. The sense of touch is crucial to everyday tasks: People without _ may have difficulty cracking an egg, lifting a cup or even turning a doorknob. That's why restoring it is a major goal for designers of artificial limbs. In their new study, Bensmaia and his co-workers worked with rhesus monkeys . The scientists implanted electrodes --- small devices that can detect and relay an electrical signal--into the animals' brains. The scientists used the electrode data to identify which neurons had become active. Then the scientists used the implanted electrodes to zap those same neurons. And the monkeys reacted as though their fingers had been touched. In fact, they hadn't. The monkeys couldn't use words to tell the scientists what they had felt. Instead, they communicated by looking in a particular direction--just as when they had really been touched. The new findings show how touch-sensitive devices could be built. The new study also offers " a nice clear pathway" for figuring out how to restore a sense of touch to an amputee or someone with a injury of spinal cord. The study shows how artificial limbs might be connected to the brain so that a person can "feel" with... Question: The passage is mainly about _ . - restoring a sense of touch - fooling a clever monkey - making new artificial limbs - sending a signal with a touch

Q: Read the following article and select the best answer. Article: Wearing seat belt is,of course,the first step to safe driving.These additional measures might also save your life. Count to three.Keeping up enough space between your car and others is extreme1y necessary.Jim Clark,a California driving instructor,suggests a least amount of three seconds'following distance.To figure this,pick an object on the roadside ahead.When the car in front of you passes it,start counting one-thousand-one,one-thousand-two,one-thousand-three.If you get to that object before you reach one-thousand-three,you don't have three seconds of following time --- time needed to keep away from accidents. Let followers pass."If someone's driving after you,get out of his way,"Clark advises."You're better of being safe than right." Expect the worst.In a study,the Federal Highway Administration found that 68 percent of drivers do not come to a complete stop at stop signs.When you're driving and see someone come near to a stop sing,assume the person's not going to stop. And when you stop at a crossing and another car comes near with its turn signal on,don't take it true that the driver will turn.Instead,wait until he turns.He may have had the signal on for miles. Stay outside.In crowd,multilane traffic,drive in either the outside--left or outside--right lane."That allows you somewhere to go if a problem develops,"traffic expert Francis Kenel says."If you're in the middle,all you can do is to pause from time to time." Question: According to the text if you want to drive safely you should . - wear seat belt - take some additional measures - at least take 5 steps - count to three
A: at least take 5 steps
