Question: Read the following article and select the best answer. Article: Cold weather can be hard on pets,just like it can be hard on people.Sometimes owners forget that their pets are just as used to the warm shelter as they are.Some owners will leave their animals outside for a long period of time,thinking that all animals are used to living outdoors.This can put their pets in danger of serious illness.There are things you can do to keep your animal warm and safe. Keep your pets inside as much as you can when the weather is bad.If you have to take them out,stay outside with them.When you're cold enough to go inside,they probably are too.If you must leave them outside for a long time,make sure they have a warm,solid shelter against the wind,thick bedding,and plenty of non-frozen water. If left alone outside,dogs and cats can be very smart in their search for warm shelter.They can dig into snow banks or hide somewhere.Watch them closely when they are left outdoors,and provide them with shelter of good quality.Keep an eye on your pet's water.Sometimes owners don't realise that a water bowl has frozen and their pet can't get anything to drink.Animals that don't have clean and unfrozen water may drink dirty water outside,which may contain something unhealthy for them. Question: If pets are left on their own outdoors in cold weather,they may _ . - run short of clean water - dig deep holes for fun - dirty the snow nearby - get lost in the wild
Answer: run short of clean water

Question: Read the following article and select the best answer. Article: Since the 1970s, scientists have been searching for ways to link the brain with computers.Brain-computer interface(BCI) technology could help people with disabilities send commands to machines. Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person's thoughts. In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand.He could even talk as he watched the vehicle and guided it with his thoughts. "Our brain has billions of nerve cells.These send signals through the spinal cord to the muscles to give us the ability to move.But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says."Our system allows disabled people to communicate with external world and also to control devices." The researchers designed a special cap for the user.This head cover picks up the signals from the scalp and sends them to a computer.The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path.They help the computer react to commands from the brain. Prof.Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands."The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices.One example is this wheelchair." He says his team has set two goals.One is testing with real patients, so as to prove that this is a technology they can benefit from.And the other is to guarantee that they can use the technology over long periods of time. Question: The team will test with real patients to _ - make profits from them - prove the technology useful to them - make them live longer - learn about their physical condition
Answer: prove the technology useful to them
