Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Elephants are able to differentiate between ethnicities and sexes, and can tell an adult from a child --- all from the sound of a human voice. This is according to a study in which researchers played voice recordings to wild African elephants. The animals showed more fear when they heard the voices of adult Masai men. Livestock-herding Masai people do come into conflict with elephants, and this suggests that animals have adapted to specifically listen for and avoid them. The study is published in Proceedings of the National Academy of Sciences. Prof Karen McComb and Dr Graeme Shannon from the University of Sussex led the study. They explained that in previous research they had used similar playback experiments to show that elephants could tell --- from the sound of a lion's roar --- whether the animal was a female or a more dangerous male. Prof McComb wanted to find out if the animals used their very sharp sense of hearing to identify a potential danger from humans. The scientists recorded Masai men, women and children saying, in their own language, "Look, look over there, a group of elephants is coming". They also recorded Kamba men saying this phrase. While cattle-herding Masai people often come across free-ranging elephants, which can result in violent conflict, the Kamba people's more agricultural lifestyle does not generally bring them into aggressive touch with the animals. When the team played recordings of these different voices through a hidden loudspeaker, they found that elephant family groups reacted more fearfully in response to the voice of a Masai man, than to a Kamba man's voice. And the adult male Masai voices encouraged far more of these defensive reactions than the voices of women or boys. Options: A Masai men B Masai women C Kamba men D Kamba women Answer: A Masai men Question:
Answer: We can learn from the passage that elephants are especially afraid of _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: The first people who gave names to hurricanes were those who knew them best -- the people of Puerto Rico. The small island of Puerto Rico is in the West Indies, off the coast of Florida. This is where all the hurricanes begin that strike the east coast of the United States. Often they pass near Puerto Rico or cross it on their way north. The people of Puerto Rico expect some of these unwelcome visitors every year. Each one is named after the Saint's Day on which it arrives. Two of the most destructive storms were the Santo Ana in 1840 and the San Ciriaco in 1899. Giving girls' names to hurricanes is a fairly new idea. It all began with a story called "Storm", written by George Stewart in 1941. In it a weatherman amused himself by naming storms after girls he knew. He named one Maria. The story describes how she Maria grew and developed, and how she changed the lives of people when she struck the United States. Weathermen of the U.S. Army and Navy used the same system during World WarII. They were studying weather conditions over the Pacific Ocean. One of their duties was to warn American ships and planes when a storm was coming. Whenever they spotted one, they gave it a girl's name. The first one of the year was given a name beginning with [A]. The second one got a name beginning with [B]. They used all the letters from A to W, and still the storms kept coming. They had to use three lists from A to W to have enough names to go around. This was the first list of hurricane names that followed the alphabet. It served as a model for the system the Weather Bureau introduced in 1942. Before 1950 the Weather Bureau had no special system for naming hurricanes. When a hurricane was born down in the West Indies, the Weather Bureau simply collected information about it. It reported how fast the storm was moving and where it would go next. Weather reports warned people in the path of the hurricane, so that they could do whatever was necessary to protect themselves. This system worked out fine as long as weather reports... Options: A collect information more rapidly B warn people more efficiently C make use of military records D remember them Answer: B warn people more efficiently Question:
Answer: The Weather Bureau began naming hurricanes because it would help them _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: The global energy crisis is approaching. What can we do? Here are some steps you can take. Cooling puts the greatest stress on your summer energy bill and the power grid . Just as t tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort. Clean or replaces filters monthly or as needed. For central air conditioning systems and room air conditioners, look for the ENERGY STAR, the federal government's symbol for energy efficiency. For central air, purchase the system with the highest possible Seasonal Energy Efficiency Raton. (SEER) Use energy-efficient ceiling fans either alone or with air conditioning. Ceiling fans do a great job of circulating air. When used with air conditioning, fans allow you to raise the thermostat and cut costs. Ceiling fans cool people, not rooms, so before you leave; turn off the ceiling fan. Let a programmable thermostat! "remember for you" to automatically adjust the indoor climate with your daily and weekend patterns to reduce cooling bills by up to 10 percent. You can come home to a comfortable house without wasting energy and cresting pollution all day while you are at work. Try to make your home airtight enough to increase your comfort, make your home quieter and cleaner and reduce your cooling costs up to 20 percent. Gut your air conditioning load, and reduce pollution by planting planting leafy trees around your home and fixing reflective bricks on your roof. Close blinds or shades on south-and west-facing windows during the day, or fix shading equipment to avoid heat build-up. Turn off everything not in use: lights, TVs, computers. And use fluorescent bulbs , which provide bright, warm light while using at least two-thirds less energy, producing 70 percent less heat and lasting up to 10 times longer than incandescent bulbs . Drive the car that gets better gas mileage whenever possible if you own more than one vehicle. If you drive 12,500 miles a year, switching 10 percent of your trips from a... Options: A planting leafy trees around your home B turning off the ceiling fan before you leave your house C keeping your south-facing windows open during the day D using fluorescent bulbs instead of incandescent bulbs Answer: C keeping your south-facing windows open during the day Question:
Answer:
We can conclude from the passage that the author probably discourages _ .
