Question: Context: Many people have problems with their vision, or ability to see. Often, the problem is due to the shape of the eyes and how they focus light. Two of the most common vision problems are nearsightedness and farsightedness, which you can read about below. You may even have one of these vision problems yourself. Usually, the problems can be corrected with contact lenses or lenses in eyeglasses. In many people, they can also be corrected with laser surgery, which reshapes the outer layer of the eye. Click image to the left or use the URL below. URL: Nearsightedness, or myopia, is the condition in which nearby objects are seen clearly, but distant objects appear blurry. The Figure 1.1 shows how it occurs. The eyeball is longer (from front to back) than normal. This causes images to be focused in front of the retina instead of on the retina. Myopia can be corrected with concave lenses. The lenses focus images farther back in the eye, so they fall on the retina instead of in front of it. Q: Sometimes squinting the eyes can help someone see more clearly. Why do you think this works? A: Squinting may improve focus by slightly changing the shape of the eyes. When you squint, you tighten muscles around the eyes, putting pressure on the eyeballs. Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure 1.2). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. Q: Joey has hyperopia. When is he more likely to need his glasses: when he reads a book or when he watches TV? A: With hyperopia, Joey is farsighted. He can probably see the TV more clearly than the words in a book because the TV is farther away. Therefore, he is more likely to need his glasses when he reads than when he watches TV. 
 Question: in hyperopia, the eyeball is

Answer: shorter than normal.


Question: Context: The Packers' utter dominance continued with another overwhelming performance over another NFC power, the Eagles. Aaron Rodgers broke Tom Brady's mark of 288 passes at home without being intercepted. The Green Bay quarterback set several other records for passing at home, including an NFL-record 29 straight touchdown passes without an interception. The Packers scored touchdowns on all three parts of the team, offense, defense, and special teams. Julius Peppers returned an interception for a touchdown, his second of the year, and Micah Hyde returned a punt for a touchdown. The Packers got going from the very beginning. They drove 75 yards on their opening drive, but had to settle for a 27-yard field goal by Crosby. After an Eagles' punt, the Packers marched on a 13 play, 88-yard drive culminating in a 4-yard touchdown pass to Davante Adams. On the drive, the Packers converted three 3rd-and-longs and took 6:47 off the clock. The Eagles punted again, but this time Micah Hyde returned the punt 75 yards for a touchdown, giving the Packers a shocking 17-0 lead. The Eagles responded on their next possession with a 33-yard field goal by Cody Parkey early in the second quarter. The Eagles, though, had no answer for the Packers' passing game. Rodgers marched the Packers 80 yards in merely 6 plays to increase the lead to 24-3 on a 27-yard touchdown pass to Jordy Nelson. After a punt, the Packers struck again. 80 yards on another time consuming drive ending with Eddie Lacy driving in a 1-yard touchdown run, but a failed two-point conversion. The Eagles reached the Packers' 15, but settled for another 33-yard field goal as the half expired. Mark Sanchez was stripped early in the 3rd quarter with Nick Perry recovering. The Eagles defense finally made a stand and forced a punt, but the Eagles were forced to punt on their responding drive. The Eagles' defense couldn't hold this time and Crosby kicked a 33-yard field goal increasing the lead to 33-6. The Eagles buried themselves on the next drive as Sanchez threw a 52-yard pick-six to Julius Peppers (with a blocked PAT), making the score 39-6. The Eagles immediately answered, driving 80 yards (with a 4th down conversion) with Sanchez throwing a 10-yard touchdown pass to Jordan Matthews. However, the Packers struck right back with an 80yard scoring drive capped off with Rodgers throwing a screen pass to Lacy who took it 32 yards for a touchdown, pushing the lead to 46-13. However, Eagles mishaps continued as Sanchez threw an interception to Tramon Williams, but Crosby missed a field goal. Then on the following drive after reaching the Packers 40, Sanchez fumbled and Hayward returned the fumble 49 yards for a touchdown, making the score a mind boggling 53-13. The Eagles were able to March 80 yards and score on a 20-yard touchdown reception by Jeremy Maclin on their next drive closing the scoring. The Packers achieved a new franchise mark, as this was the first time ever since the franchise started playing in the NFL that they scored over 50 points in consecutive games (the Packers had scored over 50 points in 6 consecutive games as a "town team" in 1919, their first season of existence.). Green Bay improved to a record of 7-3. 
 Question: Which team scored more points, Packers or Eagles?

Answer: packers


Question: Context: Did you ever make a secret code? One way to make a code is to represent each letter of the alphabet by a different number. Then you can send a coded message by writing words as strings of digits. This is similar to how information is encoded using an electric current. The voltage of the current is changed rapidly and repeatedly to encode a message, called an electronic signal. There are two different types of electronic signals: analog signals and digital signals. Both are illustrated in Figure 23.20. A digital signal consists of pulses of voltage, created by repeatedly switching the current off and on. This type of signal encodes information as a string of 0s (current off) and 1s (current on). This is called a binary ("two-digit") code. DVDs, for example, encode sounds and pictures as digital signals. An analog signal consists of continuously changing voltage in a circuit. For example, microphones encode sounds as analog signals. Electronic components are the parts used in electronic devices such as computers. The components transmit and change electric current. They are made of materials called semiconductors. A semiconductor is a solid crystalusually consisting mainly of siliconthat can conduct current better than an electric insulator but not as well as an electric conductor. Very small amounts of other elements, such as boron or phosphorus, are added to the silicon so it can conduct current. A semiconductor is illustrated in Figure 23.21. There are two different types of semiconductors: n-type and p-type. An n-type semiconductor consists of silicon and an element such as phosphorus that gives the silicon crystal extra electrons. An n-type semiconductor is like the negative terminal in a chemical cell. A p-type semiconductor consists of silicon and an element such as boron that gives the silicon positively charged holes where electrons are missing. A p-type semiconductor is like the positive terminal in a chemical cell. Electronic components contain many semiconductors. Types of components include diodes, transistors, and inte- grated circuits. Each type is described in Table 23.2. Electronic Component Diode Transistor Integrated Circuit (Microchip) Description A diode consists of a p-type and an n-type semicon- ductor placed side by side. When a diode is connected by leads to a source of voltage, electrons flow from the n-type to the p-type semiconductor. This is the only direction that electrons can flow in a diode. This makes a diode useful for changing alternating current to direct current. A transistor consists of three semiconductors, either p- n-p or n-p-n. Current cant flow through a transistor unless a small amount of current is applied to the center semiconductor (through the base). Then a much larger current can flow through the transistor from end to end (from collector to emitter). This means that a transmitter can be used as a switch, with pulses of a small current turning a larger current on and off. A transistor can also be used to increase the amount of current flowing through a circuit. You can learn more about transistors and how they work at this URL: http An integrated circuitalso called a microchipis a tiny, flat piece of silicon that consists of layers of elec- tronic components such as transistors. An integrated circuit as small as a fingernail can contain millions of electronic components. Current flows extremely rapidly in an integrated circuit because it doesnt have far to travel. You can learn how microprocessors are made at this URL: Many of the devices you commonly use are electronic. Electronic devices include computers, mobile phones, TV remotes, DVD and CD players, game systems, MP3 players, and digital cameras. All of these devices use electric current to encode, analyze, or transmit information. Consider the computer as an example of an electronic device. A computer contains microchips with millions of tiny electronic components. Information is encoded as 0s and 1s and transmitted as electrical pulses. One digit (either 0 or 1) is called a bit, which stands for "binary digit." Each group of eight digits is called a byte. A gigabyte is a billion bytes that
