PROBLEM: Context: Coming off their Sunday night road win over the Packers, the Cowboys went home for a Week 4 NFC East showdown with the Washington Redskins. In the first quarter, the 'Boys shot first as QB Tony Romo completed a 21-yard TD pass to TE Jason Witten. In the second quarter, the Redskins took the lead as QB Jason Campbell completed a 3-yard TD pass to WR James Thrash and a 2-yard TD pass to WR Antwaan Randle El, along with kicker Shaun Suisham getting a 20-yard field goal. Dallas closed out the half with kicker Nick Folk getting a 36-yard field goal. In the third quarter, the Cowboys tied the game with Romo completing a 10-yard TD pass to WR Terrell Owens. Washington would respond with Suisham kicking a 33-yard field goal. In the fourth quarter, the Redskins increased their lead with Suisham nailing a 33-yard and a 29-yard field goal. The 'Boys tried to rally as Romo completed an 11-yard TD pass to WR Miles Austin. However, Dallas' onside kick attempt failed, preserving the Redskins' win. 
 Question: In what quarter was the longest touchdown pass?

SOLUTION: first

PROBLEM: Context: The 1688 Glorious Revolution replaced James II and VII with his Protestant daughter Mary II and her husband William III and II. Since neither Mary or her sister Anne had surviving children, the 1701 Act of Settlement ensured a Protestant successor by excluding Catholics from the English and Irish thrones, and that of Great Britain after the 1707 Act of Union. When Anne became the last Stuart monarch in 1702, her heir was the distantly related but Protestant Sophia of Hanover, not her Catholic half-brother James Francis Edward. Sophia died two months before Anne in August 1714; her son became George I and the pro-Hanoverian Whigs controlled government for the next 30 years. 
 Question: What happened first, 1701 Act of Settlement or 1707 Act of Union?

SOLUTION: 1701 act of settlement

PROBLEM: Context: The ability to see is called vision. It depends on both the eyes and the brain. The eyes sense light and form images. The brain interprets the images formed by the eyes and tells us what we are seeing. For a fascinating account of how the brain helps us see, watch this short video: .

If you did, then you know that the glasses make images on the flat screen seem more realistic by giving them depth. The images seem to jump right out of the screen toward you. Unlike many other animals, human beings and other primates normally see the world around them in three dimen- sions. Thats because we have two eyes that face the same direction but are a few inches apart. Both eyes focus on the same object at the same time but from slightly different angles. The brain uses the different images from the two eyes to determine the distance to the object. Human beings and other primates also have the ability to see in color. We have special cells inside our eyes that can distinguish different wavelengths of visible light. Visible light is light in the range of wavelengths that the human eye can sense. The exact wavelength of visible light determines its color. The function of the eye is to focus light and form images. We see some objects, such as stars and light bulbs, because they give off their own light. However, we see most objects because they reflect light from another source such as the sun. We form images of the objects when some of the reflected light enters our eyes. Look at the parts of the eye in Figure 20.12. Follow the path of light through the eye as you read about it below. 1. Light from an object passes first through the cornea. This is a clear, protective covering on the outside of the eye. 2. Then light passes through the pupil, an opening in the center of the eye. The pupil, which looks black, is surrounded by the colored part of the eye, called the iris. 3. Light entering through the pupil next passes through the lens. The lens is a clear, curved structure, like the lens of a magnifying glass. Along with the cornea, the lens focuses the light on the back of the eye. 4. The back of the eye is covered by a thin layer called the retina. This is where the image of the object normally forms. The retina consists of special light-sensing cells called rods and cones. Rods sense dim light. Cones sense different colors of light. 5. Nerve impulses from rods and cones travel to the optic nerve. It carries the nerve impulses to the brain. You probably know people who need eyeglasses or contact lenses to see clearly. Maybe you need them yourself. Lenses are used to correct vision problems. Two of the most common vision problems in young people are myopia and hyperopia. You can compare myopia and hyperopia in Figure 20.13. To learn about astigmatism, another common vision problem, watch this very short video: . MEDIA Click image to the left or use the URL below. URL: Myopia is commonly called nearsightedness. People with myopia can see nearby objects clearly, but distant objects appear blurry. Myopia occurs when images focus in front of the retina because the eyeball is too long. This vision problem can be corrected with concave lenses, which curve inward. The lenses focus images correctly on the retina. Hyperopia is commonly called farsightedness. People with hyperopia can see distant objects clearly, but nearby objects appear blurry. Hyperopia occurs when images focus in back of the retina because the eyeball is too short. This vision problem can be corrected with convex lenses, which curve outward. The lenses focus images correctly on the retina. Vision is just one of several human senses. Other human senses include hearing, touch, taste, and smell. Imagine shopping at the fruit market in Figure 20.14. It would stimulate all of these senses. You would hear the
