Read the following article and select the best answer. Article: A rapidly advancing contemporary science that is highly dependent on new tools is Earth system science. Earth system science involves observation and measurements on the Earth at all scales from the largest to the smallest. The huge amounts of data that are gathered come from many different locations and require special techniques for handling data. Important new tools that facilitate Earth system science include satellite remote sensing, small deep-sea submarines, and geographic information systems. More than any other way of gathering evidence, satellite observations continually remind us that each part of the Earth interacts with and is dependent on all other parts. Earth system science was born from the realization of that interdependence. Satellite remote sensing makes possible observations at large scales, and in many cases, measurements of factors that could not otherwise be measured. For example, the ozone hole over Antarctica--the decrease in the concentration of ozone high in the atmosphere--is measured by remote sensing, as are changes in deserts, forests, and farmlands around the world. Such measurements can be used in many areas of specialization besides Earth system science. Archaeology, for example, has benefited from satellite observations that reveal the traces of ancient trade routes across the Arabian Desert. New tools for exploring previously inaccessible areas of the Earth have also added greatly to our knowledge of the Earth system. Small deep-sea submarines allow scientists to travel to the depths of the ocean. There they have discovered new species and ecosystems thriving near deep-sea vents that emit heat, sasses, and mineral-rich water. Just as important as new methods of measurement and exploration are new ways to store and analyze data about the Earth system. Computer-based software programs known as geographic information systems, or GIS, allow a large number of data points to be stored along with their locations. These can be used to produce maps and to compare different sets of... Question: What is the main idea of the passage? - special techniques are needed to classify the huge amounts of data about Earth. - New tools provide information about Earth that was once impossible to obtain. - Advances in Earth system science have resolved many environmental problems. - Satellite remote sensing can show changes between two images taken years apart.
New tools provide information about Earth that was once impossible to obtain.

However, actually using a cell phone while driving can be life-threatening. Studies have shown that new drivers are especially prone to have an accident when they use a cell phone while driving. The reason for this is that new drivers have less experience in concentrating on driving during distractions . Also, several studies done on teen drivers found that many teens often send text messages while driving. Since text messaging involves both the hands and the eyes, this is thought to be more distracting and dangerous than when drivers use a cell phone only for speaking and listening while driving. All drivers who use a cell phone while driving are reported to be at least four times more likely to have an accident than drivers who don't use a cell phone while driving. Such studies have inspired many countries, including the United States, to have at least some bans on hand-held cell phone use while driving. However, many people feel that these restrictions are far from enough. Hand-free cell phones were still found in many studies to distract the drivers' attention even though the drivers had both hands on the wheel . In some studies, drivers themselves admitted that they sometimes become distracted when they use any type of the cell phones while driving. Some studies have shown that using a cell phone while driving is actually just as dangerous as driving drunk! Both cases can impair the drivers' concentration as well as their reaction time to other vehicles or problems on the road. If a cell phone is used in crawling traffic such as a traffic jam, it is not as likely to cause danger as when a driver uses a cell phone at even moderate speeds on twisting and turning roads. Question: Why are new drivers who use a cell phone while driving more likely to have an accident? - Because they will pay all attention to the cell phone. - Because their hands will leave the wheel. - Because their eyes will not look at the road. - Because they are more likely to be distracted.
Because they are more likely to be distracted.

The cash machine, outside a Sainsbury's store in Barham Road, Hull, attracted a big crowd of people hoping to take advantage of the fault, on Tuesday night. Police officers were eventually sent in to guard the machine and prevent anymore money from being withdrawn. The fault is thought to have affected cash machines at supermarkets across the city. It is not yet known whether the customers will have to repay the cash or how much money was taken out. A spokeswoman for Humberside Police said, "Officers were sent to the cash machine to prevent anyone else from withdrawing anymore money. We have also tried to make contact with the owners of the machine." The spokeswoman said those who benefited from the fault could be traced and could face theft charges, but investigations would only take place if the operator made a complaint. The cash machine is owned by a company called Payzone, a spokesman later confirmed. He said the fault was due to the machine being filled with notes of the wrong denomination . An investigation is underway into the incident and the machine had been taken out of service, he added. The Payzone spokesman said, "The transit company which is contracted to service this ATM has filled it up with the wrong denomination of notes, meaning it is paying out double what it should have. " He could not say how much money had been taken out of the machine, or whether it would have to be paid back. It was understood that a number of cash machines in Hull owned by other companies had also been affected by this problem, he added. Question: When it was discovered that the cash machine outside a Sainsbury's store broke down, _ . - people queued up inside the store to buy things - people asked the police to protect the cash machine - people went to other cash machines to withdraw money - people queued up at the cash machine to benefit from the fault
