Q: I can use this background: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in - ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane, with two carbon atoms. The chemical formulas and properties of methane, ethane, and several other alkanes are listed in Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally have higher boiling and melting points. Now, I have a new situation: Beth and Jane studied chemistry in school. However, Beth studied noble gasses while Jane decided to know more about alkanes. Answer this question please: Which student learned more about the smallest alkane?
A: Jane

Q: I can use this background: Generally, nearsightedness first occurs in school-age children. There is some evidence that myopia is inherited. If one or both of your parents need glasses, there is an increased chance that you will too. Individuals who spend a lot of time reading, working or playing at a computer, or doing other close visual work may also be more likely to develop nearsightedness. Because the eye continues to grow during childhood, myopia typically progresses until about age 20. However, nearsightedness may also develop in adults due to visual stress or health conditions such as diabetes. A common sign of nearsightedness is difficulty seeing distant objects like a movie screen or the TV, or the whiteboard or chalkboard in school. Now, I have a new situation: Two siblings were going to school. Mary experienced headaches, so he was sent to the eye doctor. The doctor concluded she was nearsighted and prescribed her eyeglasses. Ben had normal vision. Answer this question please: Which sibling did not spend a lot of time on the computer?
A: Ben

Q: I can use this background: Through a thickness of 10 meters (33 ft) or more, however, the intrinsic color of water (or ice) is visibly turquoise (greenish blue), as its absorption spectrum has a sharp minimum at the corresponding color of light (1/227 m1 at 418 nm). The color becomes increasingly stronger and darker with increasing thickness. (Practically no sunlight reaches the parts of the oceans below 1,000 meters (3,300 ft) of depth.) Infrared and ultraviolet light, on the other hand, is strongly absorbed by water. Now, I have a new situation: David was interested in the coloration of ocean's water. To understand the phenomenon he first observed the color of water at forty feet depth. He noted his observation as point A. Then he observed the color at hundred feet depth. He noted his observation as point B. Then he observed the color at four thousand feet depth. He noted that observation as point C. He now have some ideas how the color of water changes according to its depth. Answer this question please: Would the color be darker or lighter at point A than at point B?
A: lighter

Q: I can use this background: As shown here, pressure decreases to less than 25% of ground-level atmospheric pressure when we get to an altitude of about six miles. Since this is a common cruising altitude for commercial airplanes, pressurized cabins are needed for the comfort and survival of the passengers. This is because the density of the air decreases along with the decreasing air pressure, so there is less oxygen in a breath of air. You've probably noticed this effect in high-mountain areas, as it often feels harder to breath. Now, I have a new situation: John likes to ride on hot air balloon. Last month he rode on a balloon with his friend Keith. First they were at the ground-level. They called it camp A. Then they rose to the height of three miles. They called it camp B. Eventually, they reached six miles above ground. They called it camp C. Answer this question please: Where the air would be denser, camp A or camp B?
A:
camp A
