Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: In Yemen, you always see one type of vehicle on the road: the water truck.They travel mountain roads and cross deserts to bring Yemenis the goods more valuable than oil.It is one that only the rich can afford, with the supply regularly being cut off.Others must rely on scarce rain or charity to fight thirst. Experts say Yemen is going to be the first country in the world to run out of water.The capital, Sanaa, will run out of drinking water as early as 2025,says a report by the World Bank. Hannan, an 18yearold from Lahej, said that only the rich could prepare for cuts in supply."In a good week we'll have a water supply all week but then the following week there will be water only for a day or two, " she said. She and her husband, a factory worker, pay 3,000 riyals (99yuan) for a week's supply of water from a touring water truck when the taps run dry.With an income of only 20,000 riyals (660yuan) a month,this means the family often spend half their money on water. "There are a lot of people who can't afford it and they have to rely on their neighbors to help," she said. The average person in Yemen survives on onefifth of what the World Health Organization considers to be enough water. In Taiz, in the south,tap water is available only once every 45 days.In the mountainous Malhan district in the north,women and children climb a 1,500m mountain to collect water from a spring, often in the small hours to avoid long queues. Yemen is located in Southwest Asia,bordering the Arabian and Red Sea.Yemeni people have lived on scarce water supplies for thousands of years but that problem has been made serious by conflict in the area,the fastgrowing population and the use of water to grow a drug called qat.With one of the world's highest rates of population growth--3.46 percent, Yemen is the poorest Arab country. The government is considering desalinating seawater,but this would be expensive and it may now be too late.The only other solution is to cut down on farming, but that means importing even more food. Options: A rich people drank more water than the poor B rich people could buy water from the water trucks if there was a water supply cut C she had a rich neighbor who often helped her during water supply cuts D the rich were not affected by water supply cuts Answer: B rich people could buy water from the water trucks if there was a water supply cut Question:

A: When Hannan said that only the rich could prepare for cuts in supply,she meant that _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Research on the human brain has been attracting the attention of more and more scientists in recent years. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i.e., to transplant a chip into human brain. This innovation may make everyone's dream come true. If we compare a human brain to a hard disc, what the scientists do is to enlarge the capacity of the hard disc. There are some difficulties in such transplant experiments, but scientists never give up. Experiments were started on animals. In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U.S. turned a bear into a dolphin. The dolphin was named Ted, and the bear was named Tallin. Using the most advanced technology, deep and detailed studies were made of the swimming action memory area in Ted's brain by the scientists. They got a lot of useful information. The information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin's brain. The information saved on the chip was released by means of electric power. Recently, another memory transplant was performed at the Motor Nerve Research Institute of the University of California. The transplant was performed from a dog named "Genius" to a dog named "Idiot". "Genius" could understand and follow up to 100 gestures and orders made by its master. It was a real genius. "Idiot" was the younger brother of "Genius". It had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory. _ When the two dogs woke up, "Idiot" had all the abilities "Genius" possessed. It could follow every gesture and order given by its master. But "Genius" gave no response to its master, and in fact did not recognize him at all. Options: A the two experiments are about memory transplants B the scientists exchanged the dolphin's and the bear's brains C there is no possibility of changing the human brain D "Idiot" got only some abilities "Genius" possessed after the experiment Answer: A the two experiments are about memory transplants Question:

A: We can learn from the passage that _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: There are an extremely large number of antsworldwide. Each individual ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior. In colonies that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone , chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit. In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective intelligence greater than you would expect from itsindividual parts. Options: A not willing to share food B not found around the poles C more successful than all other animals D too many to achieve any level of organization Answer: B not found around the poles Question:

A:
We can learn from the passage that ants are _ .
