Article: "I left Tangier, my birthplace, the 13th of June 1325 with the intention of making the pilgrimage to Mecca... to leave all my friends both female and male, to abandon my home as birds abandon their nests." So begins an old manuscript in a library in Paris-the travel journal of Ibn Battuta. Almost two centuries before Columbus, Ibn Battuta set off for Mecca, returning home three decades later as one of history's great travelers. Driven by curiosity, he journeyed to remote comers of the Islamic world, traveling through 44 modern countries, three times as far as Marco Polo. Little celebrated in the West, his name is well known among Arabs. In his hometown of Tangier, a square, a hotel, a cafe, a ferry boat, and even a hamburger are named after him. Ibn Battuta stayed in Mecca as a student for several years, but the urge to travel soon took over. In one adventure, he traveled to India seeking profitable employment with the sultan of Delhi.On the way, he described his group being attacked in the open country by 80 men on foot, and two horsemen. "We fought... killing one of their horsemen and about twelve of the foot soldiers... I was hit by an arrow and my horse by another, but God in his grace preserved me... ". In Delhi, the sultan gave him the position of judge, based on his _ study at Mecca. But the sultan had an unpredictable character, and Ibn Battuta looked for an opportunity to leave. When the sultan offered to finance a trip to China, he agreed. IbnBattuta set off in three ships, but misfortune struck while he was still on the shore. A sudden storm grounded and broke up two ships, scattering treasure and drowning many people and horses. As he watched, the third ship with all his belongings and slaves (one carrying his child), was carried out to sea and never heard from again. After a lifetime of incredible adventures, Ibn Battuta was finally ordered by the sultan of Morocco to return home to share his wisdom with the world.

Read the following article and answer the question. Article: A 15-year-old Saanich student who invented a flashlight powered by body heat is heading home today from California with a big prize--and an opportunity to expand on her work. St. Michaels University School student Ann Makosinski was the only Canadian among the four winners at Google's annual international science fair, beating out thousands of other young scientists from around the world. Winning the international contest was "a total shock", Ann said from San Francisco. "I definitely think it will have an influence on my future." Ann thanked her family for encouraging her interest in science, telling the judges that her first toy was a box of transistors . Ann's prize includes a $25,000 scholarship and a "once-in-a-lifetime experience" from either the European Organization for Nuclear Research, Lego or Google for her Hollow Flashlight, which has no moving parts or batteries. Ann created the flashlight for a local science fair. The inspiration for the invention came from seeing unwanted batteries and after visits to the Philippines, where she saw the need for a battery-free flashlight. A friend at school there failed in her studies because of a lack of electricity and light to study when it became dark. In her project, Ann wrote that she "made two flashlights that do not use any batteries, harmful chemicals, or kinetic energy . They do not create any noise and will always work. The flashlight's only limitation is its need for at least a 5degC temperature difference to provide usable light." A You Tube video of Ann explaining how she created the flashlight has been viewed more than 1.4 million times. Despite her success, the private school student is undecided about her career path. Ann hopes she can find a way to combine her love of film with science. The four winners were chosen from 15 finalists from eight countries. The contest attracted thousands of entries from students in 120 countries. Question: According to the passage, Hollow Flashlight _ . Answer:

A:
is safe, noiseless and energy-saving
