By any measure, computers are among the most influential and powerful tools of the modern age. They represent the high-tech revolution that has transformed the ways in which human beings interact with each other and with the world at large. Seemingly, computers are the very definition of the modern era. Although modern computers have only been a part of our everyday world for a few decades, a discovery made just over a century ago found that the concept behind them is far older than anyone could have imagined. In fact, according to the experts who have studied an ancient Greek shipwreck, one particular "computer" dates back more than 2,000 years.Made of metal, this mechanism is approximately the size of a shoebox. It was found in 1901 by divers working off the isle of Antikythera. Uncertain of the mechanism’s function, the divers naned it after the island near which it was found. At the time, the Antikythera was in terrible shape from being underwater for so long. Its pieces had merged into a broken mass and all experts could deduce was that it had something to do with astronomy. Recently, thanks to a combination of advanced imaging methods and x-ray computer tomography, scientists have been able to re-create the possible design of the apparatus.The Antikythera mechanism once had at least 30 bronze gears with as many as 225 hand-cut teeth. Scientists believe it was designed to compute eclipses of the sun and moon a number of years into the future, as well as show the motions of the planets. While experts are still uncertain as to why the device was made, there is no doubt that its technology was at least 1,000 years ahead of its time. The passage suggests that, compared to modern computers, the Antikythera（）

The male/female gender binary dominates Western culture, yet it is far from universal. For example, in India you might encounter a "hijra"--a member of the third sex. They are considered neither man nor woman. Although many of them are physically male, traditionally they refer to themselves as female and dress appropriately. This third gender is referenced in the earliest available records from the Indian Subcontinent, and was an established presence in the Vedic culture. There is no equivalent of hijras in the contemporary Western conceptualization of gender. Select the sentence that indicates the historical aspect of hijra.
There are few portraits in the world as famous as Leonardo da Vinci’s Mona Lisa, but the identity of the model for the legendary painting has been an enduring mystery for countless people. Now some experts believe that the young woman might have been an Italian named Lisa Gherardini, the wife of an affluent silk merchant and government figure. Other researchers suspect it might have been Isabella of Aragon, the Duchess of Milan. Whoever she was, the mystery woman certainly gave the world one of its most mysterious smiles. Which of the following sentences can be inferred about the Mona Lisa painting from this passage（）
For Questions 9 and 10, select one entry from the corresponding column of choices for each blank. Fill all blanks in the way that best completes the text.

Sending a robot into space to gather information is a viable option, but should only be regarded as that--an option. Even the most technologically advanced robots cannot and should not replace manned missions to outer space. Certainly it is cheaper and less dangerous to launch a computer probe that can gather reams of data, but often the information obtained by a machine only serves to produce more questions than it answers. Therefore, the space program should allow manned missions to follow up on those initial information-gathering robotic ventures.While manned missions are more costly than are unmanned missions, they are also more successful. Robots and astronauts use much of the same equipment in space, but a human is more capable of calibrating those instruments correctly and placing them in appropriate and useful positions. A computer is often neither as sensitive nor as accurate as a human in managing the same terrain or environmental circumstances. Robots are also not as equipped as humans to solve problems as they arise, and robots often collect data that is not helpful or even desired. A human, on the other hand, can make instant decisions about what to explore further and what to ignore. According to the passage, all of the following are advantages of humans over robots EXCEPT（）
