Q: Read the following article and select the best answer. Article: The temperature of the sun is over 5,000 degrees Fahrenheit at the surface, but it rises to perhaps more than 16 million degrees at the center. The sun is so much hotter than the earth that matter can exist only as a gas, except at the core. In the core of the sun, the pressures are so great against the gases that, despite the high temperature, there may be a small solid core. However, no one really knows, since the center of the sun can never be directly observed. Solar astronomers do know that the sun is divided into five layers or zones. Starting at the outside and going down into the sun, the zones are the corona, chromosphere, photosphere, convection zone and finally the core. The first three zones are regarded as the sun's atmosphere ends and the main body of the sun begins. The sun's outermost layer begins about 10,000 miles above the visible surface and goes outward for millions of miles. This is the only part of the sun that can be seen during an eclipse such as the one in February 1979. At any other time, the corona can be seen only when special instruments are used on cameras and telescopes to shut out the glare of the sun's rays. The corona is a brilliant, pearly white, filmy light, about as bright as the full moon. Its beautiful rays are a sensational sight during an eclipse. The corona's rays flash out in a brilliant fan that has wispy spikelike rays near the sun's north and south poles. The corona is thickest at the sun's equator. The corona rays are made up of gases streaming outward at tremendous speeds and reaching a temperature of more than 2 million degrees Fahrenheit. The rays of gas thin out as they reach the space around the planets. By the time the sun's corona rays reach the earth, they are weak and invisible. Question: Matter on the sun can exist only in the form of gas because of the sun's _ . - size - age - location - temperature
A: temperature

Q: Read the following article and select the best answer. Article: Canyoning The sports of canyoning explore the high-energy environment where water meets rock on the coast, or in river canyons. Protected by wetsuits and helmets , people jump from cliffs and waterfalls and explore caves and river canyons that would not normally be arrived at. It was pioneered in the U.K. by TYF Adventure (01437 721611, www.tyf.com) and several thousand people leap from the cliffs near St David's each year. A half day canyoning trip costs PS50 (PS30 for children under 16). Scuba diving Diving is not popular with British people. The challenges of wild waters are greater because the water is colder and not clear enough, but the coasts of Cornwall, Wales and Scotland have some of the best wreck diving in the world. The British Sub Aqua Club (0870 112 9133 www.bsac.com) and the Professional Association of Diving Instructors (01580 819688 www.padi.com) run courses teaching the important skills right up and to instructor level. Surfing The best surfing places in the UK are on the southwest coast where it is warmer and the surf is relatively steady, particularly in Cornwall. The best time of year to surf in the UK is late summer and autumn when water temperatures are at their mildest. The British Surfing Association (01479 861256 www.britsurf.co.uk) has a list of famous surf schools around the country. Rock climbing The most popular natural rocks in Britain include the Peak District, the Lake District, coastal regions, while vast areas of Scotland are a climber's paradise . Climbing courses and climbing walls can be located on the website of the British Mountaineering Council (0870 010 4878, www.thebmc.co.uk) which offers a series of short films that take the new climber through a step-by-step guide to visiting a climbing wall for the first time. Question: To go surfing, you may phone _ . - 01479 861256 - 0870 010 4878 - 01437 721611 - 0870 112 9133

Q: Read the following article and select the best answer. Article: Joey is loyal, encouraging and self-sacrificing, always putting others' interests ahead of his own. He is a hard worker, who also loves to run and play. In short, he's an ideal friend and a heroic character. Here is the thing: Joey is a horse, who appears as the main character in Steven Spielberg's new film War Horse. It is based on Michael Morpurgo's 1982 novel, which also caused the same-titled Tony Awards winning play. The film follows the saga of Joey, a racehorse that's trained for farm work under the loving care of Albert (Jeremy Irvine )after Albert's drunk father Ted(Peter Mullan ) overpays for the animal at auction . Then the World War I tears Albert and Joey apart. Joey is sold into the war effort for the British and starts his episodic adventures in Europe. Splendidly staged, the battle plots in the film are visually and impressive. And with Spielberg's unique, top-notch direction and storytelling skills, War Horse cannot escape its episodic nature, calling to mind another Spielberg film about the horrors of war and its effects upon soldiers and civilians--Saving Private Ryan. While that film shocked with horrific scenes of bleeding, it relied on a company of easily-described characters and a focused storyline to present heroic themes. Like Saving Private Ryan, War Horse clings to a series of characters, not only Albert, but also British officers, French civilians and German soldiers, who display courage in the face of danger. Everyone who comes in contact with Joey is either already in touch with their inner angel or is quickly moved to become more humane. Although none of this covers the fact that we've seen this stuff elsewhere before, the lovely sentiment will steal your heart. And the emotional signature of Spielberg can be felt as he establishes the relationship between the boy and the horse and the mood of the piece - there will be tears. Therefore, calling this beautiful, dramatically incomplete film " Saving Private Joey", is entirely justifiable. Question: In common with " Saving Private Ryan", the film War Horse _ . - is full of terrifying scenes of bleeding and killing - received the title of Tony Awards Winning Play - covers a lot of characters - tells the story happening in the Second World War
A: covers a lot of characters
