Article: Can you imagine traveling to work in a one-man submarine? Scientists believe that someday one-man submarines will be as numerous as automobiles today. One says," One day soon, men will walk on the ocean floor as they do on the street. " Perhaps during your life time, people will travel, work and live under the sea. Ships carrying oil and articles of trade will move beneath the ocean. Passenger ships will be built to travel underwater, where storms cannot delay them or make people seasick. Special underwater ships will be designed for mining, fishing, and exploring unknown areas. For military use, there may be submarines that can fly and then dive underwater to approach the battle area without being seen. First, however, the human problems associated with living in the ocean will need to be studied in detail. Many of these problems are the same as the problems of living in outer space: pressure, lack of oxygen, and weightlessness. Already scientists have begun to study these problems. In 1963 and 1964 scientists and Navy divers lived and worked underwater for several days in two projects which were called Sealab I and Sealab II. The Sealab II experiment kept the scientists and divers 215 feet below the surface for thirty days, studying marine biology, temperature, pressure, currents, and ocean bottom geology. Many puzzling questions remain unanswered, however. Man's warm blood makes it difficult for him to live long in the sea without some kind of warmth. Can our blood be changed to fit new water surroundings? What will happen to our muscles if we live in the water very long? Will they become soft away from our usual land existence? Will bones become weak and our blood pressure change? Scientists are searching for answers. By studying plants and animals deep in the ocean, scientists may find a cure for some of our most serious human diseases. We may learn to use plants to increase our world food supply. Engineers may learn to use the power of the sea by building huge walls to catch the force of... Question: Whether we live in the sea or in outer space, first of all we should think of _ Yes or no, is the answer "pressure, oxygen and gravity"?
No

Q: Article: Most people know Alexander Graham Bell invented the telephone. But not many know about another talking device (equipment) he invented just four years later, in 1880. He called the device the photophone. "Photophone" comes form the Greek words for "light" and "sound". The photophone did not use electricity to carry sound over wires between two people. _ . Instead, the photophone used a beam of sunlight traveling through the air. With his invention, Bell could actually transmit human speech on a beam of light. To do so, he spoke close to a thin mirror that was reflecting sunlight. The vibrations of his voice caused the mirror to vibrate, and the vibrating mirror caused the light to vibrate. The vibrating light hit a light-sensitive cell in a receiver placed some distance away. The cell changed the light patterns into electrical signals. Earphones changed the signals back into sounds. Bell believed that his idea of talking on a beam of light would prove to be important. He often called the photophone his greatest invention. Even though the photophone depended on a source of energy that was not constant--the sun--Bell wasn't a bit discouraged. He felt sure that people would one day talk using beams of light. Two much more recent developments made Bell's dream come true. In 1960, a scientist built the laser. A laser produces a highly concentrated beam of light. Shortly afterward, other scientists developed a new kind of optical fiber. The optical fiber is a glass thread. The new fiber could carry light beams long distances--as far as several miles. Question: Which statement is TRUE about Bell's invention of photophone? Yes or no, is the answer "The laser and the optical fiber are helpful for Bell's invention."?
A: No
