In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Article: As many people hit middle age, they often start to notice that their memory and mental attention are not what they used to be. We suddenly can't remember where we put the keys just a moment ago, or an old friend's name, or the name of an old band we used to love. It happens to most of us, but is it unavoidable? Scientists are increasingly showing that there's actually a lot that can be done. It turns that the brain needs exercise in much the same way as our muscles do, and the right mental workouts can improve our basic cognitive functions. Now, a new San Francisco Web-based company has taken it a step further and developed the first "brain training program" designed to actually help people improve and regain their mental sharpness. Called Lumosity, it was designed by some of the leading experts from Stanford University. Lumosity is far more than an online place to exercise your mental skills. That's because they have combined these exercises with a Web-based program that allows you to systematically improve your memory and attention skills. Apparently it works. One study showed students improved their scores on math tests by 34 percent after using Lumosity for six weeks, greater gains than those made by other students in the same class, who were not training with the Lumosity program. The company says its users have reported clearer and quicker thinking, improved memory for names, numbers, directions, increased alertness and awareness, high mood, and better concentration at work or while driving.
Answer: To improve students' scores on test.
What is the purpose of Lumosity?

Article: A powerful earthquake struck the northeastern coast of Japan at two forty-six p.m. local time on March eleventh.2011. Japan's Meteorological Agency released its first tsunami warnings just three minutes later. The country has one of the best earthquake early warning systems in the world. There are more than four thousand Seismic Intensity Meters in place throughout Japan to measure earthquake activity. These meters provide information within two minutes of an earthquake happening. Information about the strength and the center of the earthquake can be learned within three minutes. There are also concrete sea walls around much of the Japanese coastline. But these measures proved no match for the powerful earthquake and tsunami. Costas Synolakis ,a tsunami expert at the University of Southern California in Los Angeles said,"Japan is one of those most well-prepared countries on earth in terms of tsunami warning. They had a warning. I think what went wrong is that they had not expected the size of this event." He says there are two reasons for this. Japan has not had any event anywhere near as big as this one in the last one hundred fifty years. And scientists had not expected such a large earthquake happening off the coast of Japan. The nine point zero magnitude earthquake was the fourth most powerful earthquake ever recorded worldwide. It was also the worst earthquake ever to hit Japan. The tsunami waves that followed were reported to have reached as high as thirteen meters in some areas. Costas Synolakis says Japan's concrete sea walls were not built to handle such high waves. Experts say early warning systems will continue to be limited by these facts until earthquakes and tsunamis can be predicted

Article: A famous American John Muir said in 1898: "The Grand Canyon... as unearthly in the color and grandeur of its architecture as if you had found it after death on some other star." Like Muir, those of us who stand along the rim are prompted to wonder about the unearthliness and the forces that created and are still changing this place. After more than 100 years of studies, many things are still mysterious. Today visitors come by the thousands -- the great and simple of the earth -- all in a spirit of wonder. Travelers come from every state of the Union, from every country in Europe and Asia. From the depths of the canyon comes welling silence. Seldom can you hear the roar of the river, for all sounds are swallowed in this gulf of space. "It makes one want to murmur." A woman once whispered to her companion. This silence is not the silence of death; rather, it is a presence. It is like a great piece of music. But music made of man works up to a climax and stops. Now, visitors to the South Rim alone may number 18,000 in a single day. Some of that number will travel by mule train down Bright Angel Trail to the canyon's floor, cross the raging river by a suspension bridge and walk to the North Rim. Though the two rims face each other across only 12 miles, it is a journey of 214 miles by car from one to the other. Nor can you visit the North Rim except in summer; some 1,200 feet higher than the South Rim, it is snow covered much of the year except in July and August. But there is no day that you may not visit the South Rim and find the sun warm on your face and the air perfumed with the incense of smoke from an Indian hearth . No wonder an American writer and journalist said, "I came here an atheist , and departed a devout believer."
Answer: The unearthliness and the grandeur of its architecture.
What is it that attracts so many travelers to the Canyon?
