I'm taking a test and have to guess the right answer to the question after the article. Article: A new pollen study showed that drought was responsible for the extinction of civilizations more than 3,000 years ago during the Bronze Age. The reason behind why the civilizations in and around modern-day Israel suddenly broke down more than 3,000 years ago has remained a mystery up until now. A new pollen study by Tel Aviv University researchers finally solved this Bronze Age mystery. Prof. Israel Finkelstein showed that owing to serious climate changes, the entire world of the Bronze Age _ in a short period of time. The discovery was made on the basis of a high-resolution analysis of pollen grains taken from sediments beneath the Sea of Galilee and the western shore of the Dead Sea. Prof. Finkelstein received support from the European Research Council to conduct research aimed at reconstructing ancient Israel. Researchers of the part of the project that dealt with climate change extracted about 60 feet of samples of gray muddy sediment from the center of the Sea of Galilee in northern Israel. They had to drill through 1,000 feet of water and into 65 feet of the lake bed and were able to recover evidence dating over the past 9,000 years. "Pollen is the most enduring organic material in nature," explained Dr. Dafna Langgut, a pollen researcher who carried out the actual work of sampling. "These grains tell us about the plants that grew near the lake in the past and therefore prove the climatic conditions in the region." Researchers noted a sharp decrease in Mediterranean trees like oaks and pines in the Late Bronze Age. According to study experts, this could be because of repeated periods of drought. The droughts may have resulted in long famines, forcing people to migrate from north to south. Question: Prof. Finkelstein conducted the new pollen study to _ . Options: A: earn some money B: recreate ancient Israel C: learn more about local plants D: discover the ancient civilizations

I'm taking a test and have to guess the right answer to the question after the article. Article: Officials say the islands of Tokelau in the South Pacific Ocean have become the world's first territory totally powered by the sun.The move is expected to save money and ease the environmental burden of depending on imported fossil fuels. Tokelau's three main atolls ,or islands,now have enough solar capacity to meet all of their electricity needs.Until now.Tokelau has been 100%dependent on diesel for producing electricity.That has burdened the country with heavy economic and environmental costs. The three atolls of Tokelau are about halfway between New Zealand and Hawaii and are administered by New Zealand. Each atoll received its own solar power grid system.New Zealand officials estimated the cost of the project to build the three solar grids at around seven million dollars.The last of the grids has been completed. It is estimated that oil imports make up to 30%of national income in some parts of the Pacific.The move to solar power could save Tokelau about one million dollars a year.Tokelau will now be able to spend more on social programs to help its citizens. Other South Pacific islands are attempting similar projects.The island nations of Samoa and Tuvalu are aiming to get all of their electricity from renewable sources by 2020.The Cook Islands plans to start moving to solar panels and wind turbines.And most houses in the South Pacific groups of islands will begin to use solar water heaters. East Timor's government has promised that no households in the capital,Dili,would be using firewood for cooking by 2015.It also says 50%of the country's electricity will come from renewable sources by the end of the decade. New Zealand Foreign Affairs Minister Murray McCully says the country will hold a Pacific energy summit in March this year.He said the meeting would build on the success of clean and affordable energy solutions for Tokelau,Tonga,and the Cook Islands. Question: The text is mainly about _ . Options: A: Tokelau's solar power project B: South Pacific islands'renewable energy project C: Tokelau's social programme to help its citizens D: the development of solar water heaters

I'm taking a test and have to guess the right answer to the question after the article. Article: Almost every day, we discuss the topic of health, especially for kids. But what is health? "Health" means eating well, getting enough exercise, and having a healthy weight. Let's read the following rules. They can help you stay healthy. 1 Eat _ foods, especially fruit and vegetables. We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the nutrition we need by eating different kinds of food, especially fruit and vegetables. 2 Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plenty of calcium to grow strong bones, and milk has a lot of it. Every day, you should drink at least three cups of milk (1300 milligrams of calcium), when you are 9 years old or older. You should also try to have less sugary drinks, like soda and coca. They include a lot of sugar. Sugar just includes calories, not important nutrition. 3 Listen to your body. When you are eating, notice how your body feels. When your stomach feels comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can make you unhealthy and fat. 4 Limit screen time. What's screen time? It's the amount of time you spend watching TV, movies, and playing computer games. The more time you spend on these sitting-down activities, the less time you spend playing sports, like basketball, and doing other activities like bike riding and swimming. Try to spend no more than 2 hours a day on screen time. Question: As kids, we should drink at least _ to grow strong bones. Options: A: three cups of milk B: four cups of milk C: two cups of milk D: one cup of milk
