Article: Dan Bebber is a senior research fellow at the University of Exeter in Britain. He says research has shown that wild plants and animals are moving toward Earth's North and South poles as the planet warms. Mr Bebber wanted to know if the same thing was happening with organisms that attack agricultural crops. He examined reports of first sightings of new insects and diseases around the world. The records came from CABI - the Centre for Agricultural Bioscience International. He says the group began collecting information from developing and industrialized countries years ago. Dan Bebber and his research team studied 612 different organisms - from viruses and bacteria to insects like beetles and butterflies. They found that since 1960, crop pests and diseases have been moving toward the poles at an average rate of about 3 kilometers each year. Mr Bebber says this puts the most productive farmland in the world in danger. "As new species of pests and diseases evolve and potentially the environment for them becomes more _ at higher latitudes, the pressure on the breadbaskets of the world is going to increase." Farmers face other threats. Invasive species passed through trade are also causing problems. Gene Kritsky is an Entomologist at the College of Mount St. Joseph in Ohio. He specialises in the study of insects. He says climate change may improve conditions for some invasive species. "It means that species in other parts of the world that might do well in warmer temperatures can now do well in the breadbasket of America." Another Entomologist Christian Krupke of Purdue University says the effects of these changes will depend very much on the crop, the insect and the disease. But he says the research is a warning sign that people should care about climate change and do something about it.
Question: The purpose of Dan Bebber's research was to find _ .
Options: (A) if farmland could be moved to colder places thanks to global warming (B) if diseases and insects harmful to crops were going towards colder areas (C) if organisms were moving to the north and south poles (D) if the number of crop pests was increasing

Article: It seems that there is no middle ground when it comes to cats. People either love them or hate them. These feelings are not new either. All through history, cats have been worshiped or hated. A study of ancient writings and evidence found in tombs indicates that for the past 5,000 years, cats have been kept as pets in China, Arabia, Egypt, and India. However, this isn't very long compared to dogs, which have been domesticated for 50,000 years. Still, while the period in which cats have been domesticated may be quite short, it has definitely had its high and low points. Cats were at their highest position of domesticated life in ancient Egypt. There were more cats living in Egypt during the time of the pharaohs than in any other place in the world since that time. This high number of cats was probably due to the laws protecting them. Cats were associated with the moon goddess, Bast, so the Egyptians worshiped them as holy animals. If anyone was caught killing a cat, the person could be put to death. Families in Egypt also mourned the death of a cat and had the body of the dead cat wrapped in cloth before it was finally laid to rest. This respect for cats carried over to the Roman Empire where cats were the only animals allowed into temples. This fact was probably due to the ability of cats to keep the temples free of mice and rats. With the coming of the Dark Ages in Europe, the place of cats in society took a turn for the Empire, Christians began to associate cats with pegan beliefs. Cats had a reputation as helpers of witches. When a person was accused of being a witch, a cat would often be put on trial with the person. The cat would be tortured to try and make the person tell the truth, and usually the cat and the person would end up being burned in a bonfire or drowned. Bonfires of collected cats were not uncommon during this time. The days of hunting witches have ended, but other myths about cats still hold out. For a while, people in some places used to bury live cats under new buildings for good luck. As well, many people today continue to believe that black cats bring bad luck. If a black cat walks in front of a person, that person must take extra care in the near future to watch out for dangerous situations. Regardless of superstition , cats remain a popular pet today. Some cat experts believe that a cat never truly be domesticated because it may turn wild and run away at any time. However, this claim has not put people off keeping cats in their homes. A third of homes in the United States have cats, and one out of every three of these homes keeps both a dog and a cat. Especially in large cities, many people in small apartments have found that cats make much better pets than dogs. Cats may not be worshiped as gods any more, but there are people who seem to think of their cat as their children. These cat owners will do almost anything to keep their pets healthy and happy. For those cat owners who have always wondered what their pets are trying to tell them, a Japanese company may have come up with the perfect invention. In 2003, the Takara Company announced the Meowlingual, a cat translation device. The Meowlingual uses a microphone, display, and cat voice analyzer to analyze a cat's meows to determine which of 200 phrases a cat is trying to say. According to a company spokesperson, "... cat owners all over the world have been telling Takara, ' We want a cat translator!'" Now, the company "is making their dream come true by bringing in a new era of communication between cat lovers and their pets."
Question: Which of these is NOT discussed in the passage?
Options: (A) the status of cats throughout history (B) the evolution of different species of cats (C) the popularity of the cats today (D) communication between cats and their owners

However, over time , more and more people began to agree with Watson and The Vegan Society. People become vegans for many reasons. Watson and his friend stopped eating because they loved animals.
