input with options: Read the following article and answer the question. Article: Besides providing an ideal environment for sea plants and animals to live in, seawater has other values, one of which is that it constantly moves, and its movements produce energy. The most obvious movements are waves and the tides. Winds causes the waves, and the gravitational pull of the moon and the son causes tides. In places like the Bay of Fundy in Canada, the difference between the high and low tide level can be as much as 40 feet. France and Britain are now trying to use energy in the tides to produce electricity. Waves can produce electricity and some experiments are taking place to learn more about this. One of the most encouraging areas of research uses the difference between the temperature of seawater at the surface and deep down to produce electricity. Question: According to the passage, which of the following is not true? Answer:
OPTIONS:
- The temperature difference of seawater can produce electricity.
- The energy in the tides can produce electricity.
- Waves can produce electricity.
- The plants and animals in the ocean can produce electricity.
output: The energy in the tides can produce electricity.

Q: Read the following article and answer the question. Article: If cars had wings, they could fly and that just might happen, beginning in 2012. The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its car-plane, the Transition, to customers by the end of 2012. "It's next 'wow' vehicle," said Terrafugia vice president Richard Gersh. "Anybody can buy a Ferrari, but as we say, Ferraris don't fly." The car-plane has wings that unfold for flying-a process the company says takes one minute-and fold back up for driving. A runway is still required to take off and land. The Transition is being marketed more as a plane that drives than a car that flies, although it is both. The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations. The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble from trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you're good to go. When you land, you hold up the wings and hit the road. There are no expensive parking fees because you don't have to store it at an airport-you park it in the garage at home. The car-plane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers. Thrrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under the bad weather instead of flying into marginal  conditions. The Transition's price tag: $194,000. But there may be additional charges for options like a radio, , a transponder or a GPS. Another option is a full-plane parachute. "If you get into a very awful situation, it is the necessary safety option." Gersh said. So far, the company has more than 70 orders with deposits. "We're working very closely with them, but there are still some remaining steps," Brown said. Question: It takes the car-plane one minute to   _  . Answer:

OPTIONS:
- fold and unfold its wings
- unfold wings for flying
- land in the airport
- meet flying safety regulations

A: unfold wings for flying

- Human memory can fail sometimes.
- Bumblebees make false memories too.
- Humans are not as clever as bumblebees.
- Bumblebees have extraordinary memory. Now, answer this question: Read the following article and answer the question. Article: It's well known that our human memory can fail us. People can be forgetful, and they can sometimes also "remember" things incorrectly, with damaging consequences in the classroom, courtroom, and other areas of life. Now, researchers show for the first time that bumblebees  can be unreliable witnesses too. Bumblebees are rather clever animals, which explains why Chittka has been studying learning and memory in the insects for the last 20 years. Most times when people have studied memory in animals, errors in performance have been taken to mean that the animals failed to learn the task or perhaps learned it and then forgot. But what if animals can experience a more interesting type of memory failure? To find out, Chittka first trained bumblebees to expect a reward when visiting a yellow artificial flower followed by one with black-and-white rings. During subsequent tests, bees were given a choice between three types of flowers. Two were the types they'd seen in the training before. The third had yellow-and-white rings, representing a mixed-up version of the other two. Minutes after the training, the bees showed a clear preference for the flower that recently rewarded them. One or three days later, however, something very different happened when the bumblebees' memory was put to the test. At first, the bees showed the same preference displayed in the earlier tests, but as the time went on, they began selecting the flower with yellow rings, even though they'd never actually seen that one in training before. Chittka says that insects make similar errors in the conjunction   of long-term memories as humans do. The ability to extract   common features between different events in the environment might come at the expense of remembering every detail correctly. In bees, with their limited brain capacity  , the pressure to store main features of several objects rather than each individual object might be much greater, compared with humans. Question: Which of the following might be the best title of the passage? Answer:
A:
output: Bumblebees make false memories too.

Read the following article and answer the question. Article: Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer? This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes -- clothes that have minds of their own! Scientists, working for the company, have invented a kind of fabric that can be blended  with flexible electronic materials to create intelligent clothing. The result are electronic garments. If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable!! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100 percent shock proof, they say. The Electrotextiles team has also created the world's first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These 'lap- tap' gadgets  are all set to take over laptop computers! Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim  jacket with flexible earphones sewn into the hood  and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids. Having completed the cloth keyboard, scientists have already started to work on a new project--a necktie that can be used as a computer mouse. What is the next? Do you have any idea? Question: . How will researchers improve these high-tech clothes? Answer:

OPTIONS:
- Body heat will be used as power.
- The wearer will not get shocked.
- A tiny nine-volt battery will work.
- They will get charged automatically.

Answer:
Body heat will be used as power.
