[EX Q]: Article: An annoying problem for humans, who like to boast about all the distant planets and moons we have explored, is that we've never taken a good look right under our noses. The inside of the earth is relatively close, but how can we get there? The deepest oil well enters a mere six miles into the crust (the center of the earth is about 4,000 miles deeper). Russian scientists dug the deepest hole in Siberia, but bottomed out at about 7.5 miles below the surface. The Mohole project, a U.S. plan in the 1950s, called for drilling a hole 25 miles down to the boundary between the hard rocks of the crust and the soft mantle . Sadly the project involved government supporting. It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust --- about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible. What little we know about the inside of the earth (like the fact that there's a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes. So maybe it's time for a thorough new method to explore the earth's inside. Scientist David Stevenson says we should forget about drilling holes. Instead, we should open a crack . Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb. Next, he'd pour a few hundred thousand tons of molten iron into the crack, along with a robot. The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper. The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the surface. Stevenson compares his idea to space exploration. "We're going somewhere we haven't been before,"he says. "In all possibility, there will be surprises." This idea can probably be put in the drawer marked with Isn't Going To Happen. The robot would have to survive temperatures that would melt pretty much anything. But Stevenson's idea may inspire a new look at an old problem. Great things can come from what seems like impossible ideas.

[EX Q]: Article: Three-point-four billion riders on New York City subways and buses a year. This amazing number equals one-third of all mass transit trips in the United States. Ridership is at its highest in almost 60 years in almost every American city. A commuter advocacy group, "Straphangers Campaign," attributes it to younger Americans, said Gene Russianoff. "Millenials , those people born around the turn of the past century are much less car-oriented," he said. "They are urban. They like not owning cars, they like less responsibility and there are a lot of them." In addition to millenials, many people believe public transit is economical and eco-friendly. In 2012 across America, people took 10.7 billion trips. "When we talk about insurance rates going up, price of automobiles going up, then people are waking up and realizing: wait, here's this huge asset that has been _ ," said Richard Rudolph, chairman of the Rail Users Network. "Why not take advantage of this particular opportunity. It certainly makes more sense to get people out of automobiles into subways and into commuter and passenger railroads." _ -- as passenger demand requires several major expansion projects. A new $4.5 billion subway line on New York's Second Avenue -- which was recently excavated underneath businesses and apartment houses -- will take an overload of passengers off of other subway lines. Its first phase completion is scheduled in 2016. People who work in New York's financial district will soon be using a new transit subway transfer center. Almost all lines converge in lower Manhattan and the new center will give riders an easier way to get around the city and into New Jersey. And, probably the most controversial and costly project is a $7 billion tunnel connection from Long Island into Manhattan's Grand Central Terminal. Trains from there will have access to New York's midtown business district. Andrew Albert, a board member of the Metropolitan Transit Authority, said there were many other reasons the public was riding in increasing numbers. "The system has gotten a lot more dependable. We have new cars. We have countdown clocks to tell you when the next train is coming. We have expanded facilities in places," he said. New York's 24-hour, 7-day-a-week, transit system costs a $1.5 billion a year to maintain. It is one of the world's oldest, with its first subway line having opened in 1904.
Question: Which is Not the reason why the public is riding subways and buses in increasing numbers.
Options: (A) Public transport facilities are better than before. (B) Many people believe public transit is economical and eco-friendly. (C) The system has gotten a lot more dependable. (D) It is more convenient to ride city subways and buses.

[EX Q]: Article: People who are hit by lightning and survive often have long-term effects. These may include memory loss, sleep disorders, muscle pain and depression . Experts tell people to seek the safety of a building or a hard-top vehicle any time they hear thunder, even if it is not raining. They say lightning can strike as far as sixteen kilometers from any rainfall. Lightning can travel sideways. And at least ten percent of lightning happens without any clouds overhead that you can see. People who are outdoors should make sure they are not the tallest thing around. Bend low to the ground, but do not lie down. And do not stand near a tree or any tall object. Get away from water and anything made of metal. A car is safe, but do not touch any metal inside. Safety experts say people in buildings should stay away from anything with wires or pipes that lead to the outside. The National Weather Service says if you plan to _ any electronic equipment, do so before the storm arrives. Do not use a wired telephone. Do not use water. All these can carry electricity. Some people think a person struck by lightning carries an electrical charge afterward. Experts say this is not true. It is safe to begin emergency treatment. Each year about four hundred people in the United States are struck by lightning. Last year forty four people died. The average is close to seventy. The National Weather Service says that is more than the number of people killed by severe storms.
Question: According to the passage, which of the following is NOT true?
Options: (A) Lightning can happen even if there is no cloud. (B) Lightning won't do harm to people's health. (C) Lightning can travel sideways. (D) Lightning can strike very far.
Asnwer: B
