Write a multi-choice question for the following article: Article: The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms. After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London. Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London. "The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire. At the peak of the cycle, violent outbursts called coronalmass ejections occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots. Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available. The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares and explosions as they occur. Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If...

Write a multi-choice question for the following article: Article: A unique thermo-solar power station Germasolar in southern Spain can work even on cloudy days:energy stored when the sun shines lets it produce electricity even during the night. It is the first solar power station in the world that works 24 hours a day! This is how it works: the panels reflect the sun's rays onto the tower, transmitting energy 1,000 times stronger than that of the sun's rays reaching the earth. Energy is stored in tanks, and then steam is produced before finally turned into electricity. It is the station's capacity to store plenty of energy that makes Gemasolar so different because it allows the plant to transmit power during the night, relying on energy it has gained during the day. Helped by the generous state aid, renewable energies have enjoyed a boom in Spain, the world number two in solar energy and the biggest wind power producer in Europe, ahead of Germany. For the Gemasolar solar product, foreign investors helped too: Torresol Energy is a joint enterprise between the Spanish engineering group Sener, which holds 60 percent, and Abu Dhabi-financed renewable energy firm Masdar. This type of station is expensive, not because of the raw material we use, which is free solar energy, but because of the enormous investment these plants require. The investment cost is over 200 million euros ($ 260 million). But the day when the business has repaid that money to the banks (maybe, in 18 years, someone estimates), this station will become a 1,000-euro note printing machine! For now, the economic crisis has nevertheless cast a shadow over this kind of project: Spain is battling to cut its deficit as it slides into a difficult time and has cancelled aid to new renewable energy projects.

Write a multi-choice question for the following article: Article: Saturday, March 24th We have arrived in the hot, wet city of Bangkok. This is our first trip toThailand . All the different smells make us want to try the food. We aregoing to eat something special for dinner tonight. The hotel we are staying in is cheap, and very clean. We plan to stay here for a few days, visit some places in the city, and then travel to Chiang Mai in the North. Tuesday, March 27th Bangkok is wonderful and surprising! The places are interesting. We visited the famous market which was on water, and saw a lot of fruits and vegetables. Everything is so colorful, and we have taken hundreds of photos already! Later today we will leave for Chiang Mai. We will take the train north, stay in Chiang Mai for two days, and then catch a bus to Chiang Rai. Friday, March 30th Our trip to Chiang Rai was long and boring. We visited a small village in the mountains. The village people here love the quiet life-no computers or phones. They are the kindest people I have ever met. They always smile and say "hello". Kathy and I can only speak a few words of Thai, so smiling is the best way to show our kindness. I feel good here and hope to be able to come back next year.
