Question: 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.

Answer: A

Question: Article: The red crab lives on Christmas Island in the Indian Ocean and has been found nowhere else in the world. But on its homeland it is a very significant species -- some 120 million individuals cover the rain forest floor and play a major role in determining the structure of the ecosystem. These large crabs are active during the day but prefer to stay in the shade and can die in the heat of direct sunlight. They feed on fallen leaves, seeds, fruits and flowers, recycling nutrients and helping to determine the spread and composition of native plants. Most of the year the red crabs live in the holes they dig throughout the forest. During the dry season they hide in these shelters to keep their body wet and remain there for two to three months. But when wet season returns in October or November they begin a legendary mass migration to their seaside breeding grounds, moving in color1ful wave that wash over all obstacles like roads (including special passages and some closed roads built for the red crab) and even seaside cliffs. The annual migration is also closely tied to the lunar schedule. The crabs arrive at the coast and breed at such a time that the females can produce eggs and develop them in caves for a dozen or so days before carrying them into the sea exactly when high tide turns between the last quarter and new moon. During this period sea level on the beaches varies the least and offers an easier approach, which is so important that if the weather delays the migration crabs will put off laying eggs until the next lunar month. Red crab eggs grow right away, and the young live in the sea for a month before returning to the coast, changing into air breathers, and slowly returning inland to begin the cycle once again.
Question: The red crab is a very significant species on its homeland because _ .
Options: (A) it's gradually dying out (B) it's not found anywhere else (C) it's well protected by the local people (D) its huge population affects its native ecosystem

Answer: D
