Q: Read the following article and select the best answer. Article: You stare at waterfall for a minute or two, and then shift your gaze to its surroundings. What you now see appears to drift upward. These optical illusions occur because the brain is constantly matching its model of reality to signals from the body's sensors and interpreting what must be happening--that your brain must have moved, not the other; that downward motions is now normal, so a change from it must now be perceived as upward motion. The sensors that make this magic are of two kinds. Each eye contains about 120 million rods , which provide somewhat blurry black and white vision. These are the windows of night vision; once adapted to the dark, they can detect a candle burning ten miles away. Color vision in each eye comes from six to seven million structures called cones . Under ideal conditions, every cone can "see" the entire rainbow spectrum of visible color1s, but one type of cone is most sensitive to red, another to green, a third to blue. Rods and cones send their messages pulsing an average 20 to 25 times per second along the optic nerve. We see an image for a fraction of a second longer than it actually appears. In movies, reels of still photographs are projected onto screens at 24 frames per second, tricking our eyes into seeing a continuous moving picture. Like apparent motion, color1 vision is also subject to unusual effects. When day gives way to night, twilight brings what the poet T.S. Eliot called "the violet hour." A light levels fall, the rods become progressively less responsive. Rods are most sensitive to the shorter wavelengths of blue and green, and they impart a strange vividness to the garden's blue flowers. However, look at a white shirt during the reddish light of sunset, and you'll still see it in its "true" color1--white, not red. Our eyes are constantly comparing an object against its surroundings. They therefore observe the effect of a shift in the color1 of illuminating on both, and adjust accordingly. The eyes can distinguish several million graduations of light and shade... Question: The visual sensor that is capable of distinguishing shades of color1 is called _ . - cones - color1 vision - rods - spectrum
A: cones

Q: Read the following article and select the best answer. Article: Back in the fifteenth century, in a tiny village near Nuremberg, lived a family with eighteen children.In spite of the hopeless condition, two of the children, Albrecht Durer and Albert, had a dream.They both wanted to pursue their talent for art.After many long discussions, the two boys finally worked out an agreement.They would toss a coin.The loser would go down into the nearby mines and, with his earnings, support his brother who attended the academy.Then, when that brother who won the toss completed his studies, in four years, he would support the other brother at the academy. Tossing a coin, Albrecht Durer won and went off to Nuremberg.Albert went down into the dangerous mines and, for the next four years, supported his brother, _ work at the academy was almost an immediate sensation .By the time he graduated, he had earned considerable fees for his outstanding works. When the young artist returned to his village, the Durer family held a festive dinner to celebrate Albrecht's triumphant homecoming.Albrecht drank a toast to his beloved brother for the years of sacrifice that had enabled him to complete his dream."And now, Albert, blessed brother of mine, now it is your turn.Now you can go to Nuremberg to look for your dream, and I will take care of you." Tears streaming down his pale face, Albert sobbed, "No...no...It is too late for me.Look...look at what four years in the mines have done to my hands!The bones in every finger have been broken at least once, and lately I have been suffering from arthritis so badly in my right hand that I cannot even hold a glass to return your toast, much less draw delicate lines with a pen or a brush." To show thanks to Albert for all that he had sacrificed, Albrecht Durer painstakingly drew his brother's injured hands with palms together and thin fingers stretched skyward.He called his powerful drawing simply "Hands", but the entire world almost immediately opened their hearts to his great masterpiece and renamed it "The Praying Hands".The next time you see a copy of...
