Ques:Read the following article and select the best answer. Article: Have you ever asked yourself why you have two eyes instead of one, three, or even hundreds as some insects have? Have you wondered why your eyes are set close together on the front of your face rather than on the sides of your head, as on animals like rabbits, antelopes, and horses? The reasons are simple -- and important to the way you see the rest of your world. Your eyes are like two small cameras. A camera catches an image of an object and records this image in miniature on a small piece of film. Similarly, when you look at something, each eye takes in what it sees and sends this image to the back of the eyeball. From each eye, an optic nerve then sends the image to the brain. Because your eyes are set close together, they view the world from about the same height but from slightly different angles. While your right eye sees an object a little to the right, your left eye sees the same object slightly to the left. Working as a team, the eyes send the images to the part of your brain called the cerebral cortex, which combines them into a single, centered image. Seeing with two eyes working together is called stereoscopic vision. This allows you to view the world in three dimensions, or 3-D. These dimensions are height, width, and depth. Sensing depth allows you to judge the distance between you and the objects you see. It also helps you to adjust to the changing angle at which you see something as you move closer to or farther away from it. As you walk along a sidewalk, for example, seeing in stereo helps you to know how close you are to the street, how far you need to walk to arrive at a certain building, and how close you are to stepping on a rock or a piece of glass. As your body moves, your eyes give you a continual flow of information about where things are in relation to where you are. If images are coming from only one eye, however, only two of these dimensions - height and width - can be sensed. A world seen with one eye is thus two-dimensional, as in a photograph. The... Question: The author of this passage concludes that "seeing in stereo" _ . - is an ability humans are fortunate to have - helps people to have better vision than animals have - would be better if it allowed for a wider field of vision - is similar to the way cameras work

Ans:is an ability humans are fortunate to have

Ques:Read the following article and select the best answer. Article: The first kind of air transportation was not a plane. It was a balloon. People traveled by balloon 100 years before there were planes or jet aircraft. Those early days of ballooning were exciting, but they were also dangerous. Sometimes the balloons fell suddenly. Sometimes they burned. However, the danger did not stop the balloonists. The first real balloon flight was in France in 1783. Two Frenchmen, the Montgolfier brothers, made a balloon. They filled a very large paper bag with hot air. Hot air is lighter than cold air, so it goes up. The Montgolfier's hot air balloon went up 1,000 feet in the sky. Later that same year, two other Frenchmen ascended in a basket under a balloon. They built a fire under the balloon to make the air hot. This made the balloon stay up in the air for a few hours. But their balloon was tied to the ground. So it could not go anywhere. The first free balloon flight was in December, 1783. The balloon flew for 25 minutes over Paris. It traveled about 5.5 miles. Flying a balloon is not like flying a plane. The balloon has no engine and therefore no power of its own. The wind directs the balloon. It goes where the wind blows. The pilot can control only the altitude of the balloon to find the right wind direction. That is how a good pilot controls where the balloons goes. Soon balloonists tried longer flights. A major event in the history of ballooning was the first long flight over water. In 1785, an American and a Frenchman flew over the English Channel. During the nineteenth century, ballooning became a popular sport. There were balloon races in Europe. Balloons were also used by scientists to study the air and by armies in wartime. After the airplane was invented, people lost interest in balloons. Planes were much faster and easier to control. But some people today still like to go up in balloons. High up in the balloon basket, they find quietness. They have wonderful view of the world below. Question: One way to control a balloon is to _ . - use the engine - find the right wind direction - ask the pilot - not change altitude

Ans:
find the right wind direction
