Question: Today, many people use plants from other places to design their yards. Well, do they have any influence on animals living nearby? As we know, plants supply food for things like insects and plant-eating animals. In turn, birds and meat-eating animals feed on these insects and plant-eating animals. It is easy to see how important plants are. Although foreign plants may look beautiful, they can cause problems when there are too many of them. I live in Virginia, USA, and sometimes see a plant--commonly known as Kudzu--that seems to cover everything in the area, even climbing over whole trees and houses. Kudzu is an unbelievable plant since it grows very fast. It was first brought to the United States from south-east Asia around the 1870's as a crop that farmers could grow. However, Kudzu quickly came to be considered harmful throughout the southern United States. Since Kudzu grows fast in many different environments, it can completely cover areas of land quickly. The plant is also not eaten by any insects or birds in the United States so it can grow unchecked. Kudzu can cover trees, bushes, and even houses. It costs the United States 500 million dollars a year to just keep Kudzu from growing too fast. The plant is a perfect example of what scientists call an invasive   species, which grows more quickly than other native plants. All foreign plants have the possibility to spread quickly. Not only are they costly, but planting them in gardens actually takes away food from insects. If everyone filled their garden with plants native to where they live, many lovely butterflies and other native creatures would be attracted to their backyards! So, take a look out of your window -- how does your garden grow? We can learn from the text that Kudzu in Virginia   _  . A) is very popular B) is difficult to grow C) can cause big trouble D) can make air cleaner
Answer: C

Question: Many cities have subways and underground public transportation to take locals and tourists alike rapidly around the city.However, there's something different about riding a London subway.It may not look different, but the historical value of one of England's most popular forms of transportation is enough to make riding the subway a must when visiting London.With a little under 300 different stations, the subway can take you almost anywhere you need to go. Riding a London subway, a person from other countries will notice one major difference: in London, people do not look at each other.In fact, eye contact is avoided at all times.That's not rudeness --people are just too busy to bother looking. Busy doing what, you ask? Well, they're certainly not using the time for a moment of quiet thinking.Nor are they reading a book.New technology has replaced quiet habits.Today the only acceptable form of book on the London underground is an e-book. Apple must earn a fortune from London commuters .Since the launch of the iPhone in 2007, over 40,000--yes, that's 40,000 " _ " have been designed. Commuters love them because they are the perfect time-fillers.One "app", called iShoot, is a game that features tanks.Another one, Tube Exits, tells passengers where to sit on the train to be closest to the exit of their destination.iSteam clouds the iPhone screen when you breathe into the microphone.You can then write in the "steam" on your phone screen. For those without an iPhone, another Apple product, the iPod, may be the distraction of choice.It's not just teenagers who "plug in" to their music-iPods are a popular way to pass the time for all ages. And if games, e-books and music aren't enough to keep you occupied, then perhaps you would prefer a film? The development of palm DVD technology means many commuters watch their favorite TV shows or films on the way to work.With all these distractions, it's amazing that people still remember to get off the train. The main idea of the passage is that   _  . A) London commuters are unfriendly to strangers B) Apple has earned a lot of money from selling 40,000 apps C) technology is changing how London commuters spend their traveling time D) riding a London subway is a must when visiting London
