input question: Electronegativities generally increase from left to right across a period. This is due to an increase in nuclear charge. Alkali metals have the lowest electronegativities, while halogens have the highest. Because most noble gases do not form compounds, they do not have electronegativities. Note that there is little variation among the transition metals. Electronegativities generally decrease from top to bottom within a group due to the larger atomic size. John was studying the periodic table. To make things easier for him he divided the table in different sections, section A, section B, section C, and section D. Section A elements are located at the left of the table, but section B elements are located at the right side of the table. Section C elements are located at the top, but section D elements are located at the bottom. Would section A have more or less electronegativities than section B????
output answer: less

Mantle melting can come about three ways: (1) when the temperature rises, (2) if the pressure lowers (which lowers the melting point), and (3) if water is added, which lowers the melting point. Two of these (1 and 3) might explain why there are volcanoes at convergent plate boundaries: the temperature of the subducting plate increases as it sinks into the hot mantle (1). Sediments lying on top of the subducting plate contain water. As the sediments subduct, the water rises into the overlying mantle material. This lowers the melting temperature of the mantle (3). When the mantle above the subducting plate melts, volcanoes form above it. This leads to volcanoes in an island arc or continental arc. Two researches studied the Earth's mantle. Clint studied mantle melting, and his pal Uri decided to study other mantle related phenomena. Which researcher read less about sediments lying on top of the subducting plate?
----
Answer: Uri

Q: A vapor light also produces visible light by electroluminescence The bulb contains a small amount of solid sodium or mercury as well as a mixture of neon and argon gases. When an electric current passes through the gases, it causes the solid sodium or mercury to change to a gas and emit visible light. Sodium vapor lights, like the streetlight pictured in the Figure below , produce yellowish light. Mercury vapor lights produce bluish light. In addition to lighting city streets, vapor lights are used to light highways and stadiums. The bulbs are very bright and long lasting so they are a good choice for these places. Joey just purchased two new vapor light bulbs for his apartment and is excited to install them since they glow neat colors. He is going to install a different bulb in each room to give different colored glows to the rooms and to make his apartment seem more dynamic. In his bedroom he has decided to install a bulb that gives off a blue glow. He also picked up a bulb that glows yellow and will be putting that in his closet. However, after screwing the bulbs in, only the one in his closet glows, and Joey is not sure why. Is the bulb in the closet or bedroom filled with mercury?
A: bedroom

Question: 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 other small alkanes are listed in the 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 boil and melt at higher temperatures. Two students studied chemistry. Nate studied alkanes, and Ben studied noble gasses. They both got an A later on. Which student learned more about how many carbon atoms each molecule of the alkane has?
Answer: Nate

[Q]: 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. 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. Would there be less or more oxygen in camp B than in camp C?

[A]: more

Problem: Given the question: Just as there are good-quality grasses for putting greens, there are good-quality grasses for the fairway and rough. The quality of grass influences the roll of the ball as well as the ability of the player to "take a divot" (effectively, the ability to hit down into the ball, hitting the ball first, then hitting the turf and removing a portion of it as the club continues its arc). Fairways on prestigious tours, like the PGA Tour, are cut low. Mowing heights influence the play of the course. For example, the grass heights at U.S. Open events are alternated from one hole to the next in order to make the course more difficult. One example of this is the infamous roughs at U.S. Opens, which are often 3 to 5 inches high, depending on how close to the fairway or green the section of grass will be. This makes it difficult for a player to recover after a bad shot. The golf course at the Aurora Country Club cuts their grass to 2 1/2 inches high. The grass at the Augusta Country Club is cut to 4 inches. Sam likes more of a challenge when playing golf but Jack likes to play on turf where the ball rolls easier. Which Country Club would Sam enjoy playing golf at less, Aurora or Augusta?

The answer is:
Aurora
