Example Input: Article: John and Bobby joined the same company together just after graduation from college the same year. Both worked very hard. After several years, however, the boss promoted Bobby to the position of manager but John remained an ordinary worker. John couldn't it anymore, gave his resignation to the boss and complained that the boss only promoted those who only said good words to him. The boss knew John worked very hard for the years. He thought for a moment and said, "I hope you will do one more thing for our company before you leave." John agreed. The boss asked him to go and find anyone selling watermelons in the market. John went and returned soon. He said he had found a man selling water melons. The boss asked how much they per kilo. John shook his head and went back to the seller to ask and returned to tell the boss $1.2 per kilo. The boss told John to wait a second, and he called Bobby to come to his office. He asked Bobby to go and find anyone selling watermelons in the market. Bobby went, returned and said, "Boss, only one person is selling watermelons. $1.2 per kg, and $10 for 10 kg. He has 340 melons in all, 58 of which are on the table. Every melon weighs about 2 kg. Brought from the South two days ago, they are fresh and red. " John was impressed and realized the difference between himself and Bobby. He decided not to resign but to learn from Bobby.

Example Input: Article: A survey reveals that employees in China say they are not engaged in their jobs. Judging by the survey data, many Chinese workplaces are black holes of misery and despair. Only 6% of Chinese employees said they are "engaged" in their jobs, according to a global Gallup survey released this month. China's numbers equal the numbers out of war-weary Iraq. Workers across all income levels and industries were surveyed by Gallup in China, defined by Gallup to mean they were "psychologically committed to their jobs and likely to be making positive contributions to their organizations". Out of 94 countries polled, only six countries scored lower rates of job engagement than China, including Tunisia, Israel and Syria. Unsurprisingly, 0% of Syrians admitted to being engaged at work. In a related survey, China ranked near the bottom in a poll measuring job satisfaction among 22 Asian countries. Only 49% of Chinese respondents said they were happy in their jobs. Part of the problem, I suspect, is that very few in China have the _ to pursue a career that truly interests them. Even university graduates often feel they have no choice but to choose the positions with the government or state-run enterprises, since those jobs are thought to be stable. That makes those who are happy at work in China a rare find indeed.
Question: According to the author, why most Chinese dislike their jobs?
Options: (A) Because they don't take the jobs they really like (B) Because many Chinese workplaces are full of misery and despair. (C) Because they have no choice but to choose the stable jobs. (D) Because they are not psychologically committed to their jobs.
Example Output: A

Example Input: Article: Believe it or not, optical illusion can cut highway crashes. Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent strips, called chevrons , painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down. Now the American Automobile Association Foundations For Traffic Safety in Washington D.C. is planning to repeat Japan's success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes. Excessive speed plays a major role in as much as one fifty of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards are the greatest-curves, exit slopes, traffic circles, and bridges. Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars. Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction of highway speed and the number of traffic accidents.
Question: The passage mainly discusses _ .
Options: (A) a new way of highway speed control (B) a new pattern for painting highway (C) a new way of training drivers (D) a new type of optical illusion
Example Output:
A
