Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Competition. It's a simple word, yet a very complex word that covers many angles when it comes to how gasoline prices are determined. It seems so easy to explain, but don't let that trick you--it's incredibly difficult to explain and adequately understand. Say you're on a Sunday afternoon drive, and notice a gas station near you charging $3.50. Down the road a few miles, that price could easily be 10 or more cents higher or lower. The question is "how" or "why" is that? Think of it this way. Are you more likely to get a better deal on a car if there are two similar car dealers next to each other? Perhaps, because the dealers are too close. Say there is a third similar car dealer miles away. Is he going to be at the same level of competition and sell his cars for the same price as the two dealers next to each other? Likely not. He may charge more or less. Maybe people don't know there are two other dealers down the road. Maybe the dealer is almost outside of the city and the land value isn't as high, so his taxes aren't as high. These situations do take place at gas stations. And more factors can impact what a station will charge. Timing can greatly impact what price a station charges as well! Many motorists fail to realize that the price a station pays for gasoline changes daily. If one station gets lucky and buys gas on Monday and the cost goes up Tuesday, the station that bought on Monday doesn't necessarily have to raise prices like the station that bought on Tuesday. Maybe the station that got caught buying for a higher price on Tuesday will pass that higher cost on by raising its gas price. Perhaps the difference is what brand the station is---branded stations usually pay a slightly higher cost for their gasoline. In return for paying a higher cost, those stations are guaranteed first supply in case of emergency situations. Independent stations don't pay as much, but aren't guaranteed supply. While competition sounds easy to understand, there are always a large number of factors that could influence what... Options: A a gas station always wants to charge more B the gasoline is in great demand C the cost of the gas the station buys varies daily D gas is in greater need on Monday Answer: C the cost of the gas the station buys varies daily Question:

The gas prices of a station always change partly because _ .

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Searching the Internet may help middle-aged and older adults keep their memories sharp,US researchers said. Researchers at the University of California, Los Angeles ,studied people doing web searches by recording their brain activity. "What we saw was people who had Internet experience used more of their brain during the search,"Dr.Gary Small, a UCLA expert on aging, said,"This suggests that just searching on the Internet may train the brain and that it may keep it active and healthy." "This is the first time anyone has simulated an Internet search task while scanning the brain,"Small said. His team studied 24 normal volunteers between the ages of 55 and 76. Half were experienced at searching the Internet and the other half had no web experience. However, the two groups were similar in age, gender and education. Both groups were asked to do Internet searches and book reading tasks while their brain activity was monitored. "We found that in the book reading task, the visual cortex-- the part of the brain that controls reading and language -- was activated,"Small said,"In doing the Internet search task, there was much greater activity, but only in the Internet-savvy group." He said it appears that people who are familiar with the Internet can engage in much deeper level of brain activity. Activities that keep the brain engaged can preserve brain health and thinking ability. Small thinks learning to do Internet searches may be one of those activities. Options: A When you read, the whole brain will be activated. B Dr.Gary Small is a UCLA expert on brain health. C Internet searches can preserve brain health and thinking ability D People who read books may have a better memory. Answer: C Internet searches can preserve brain health and thinking ability Question:
