Read the following article and select the best answer. Article: "Eat local." It's one way to reduce human effect on the planet.Eating local means to try to buy and consume foods that are grown in places close to home.However, most of the food sold at supermarkets is not locally grown or produced.Trucks and planes deliver these foods from hundreds or thousands of miles away.During the transportation, greenhouse gases are produced, causing global warming.So the shorter the distance your foods must travel, the less the harm is done to the environment. But how do you get local food if you live in a large city, hundreds of miles away from farms?Environmental health scientist Dickson Despommier and his students came up with the idea of a "vertical farm". A vertical farm is a glass-walled structure that could be built as tall as a skyscraper.Since the garden is built upwards, rather than outwards, it requires much less space than an ordinary farm.The world is quickly running out of room for ordinary farming.Vertical farms could be a key to this situation.Despommier imagines a 30-story building with a greenhouse on every floor.The walls of the building would be clear, to allow crops to get as much sunlight as possible.Depending on a city's water resources, Despommier thinks hydroponic farming is another method for the vertical farm which needs no soil to grow plants. Despommier says the hydroponic greenhouses would use a system that would use a city's waste water and fill it with nutrition to make the crops grow.If this method works, it would provide food to a city and save millions of tons of water. The idea of a vertical farm has attracted the attention of government officials around the world.Scott Stringer, a government official from New York City, thinks the city is suitable for the vertical farming."Obviously we don't have much land left for us," Stringer said, "But the sky is the limit in Manhattan." Despommier admits that there is still a lot of work to do to make vertical farms a reality."But I think vertical farming is an idea that can work in a big way." he says. Question: Why are people advised to eat local? - Because it means convenience to people. - Because it can help people save a lot of money. - Because local food has more nutrition. - Because it is environmentally friendly.
Because it is environmentally friendly.

Read the following article and select the best answer. Article: New findings show that musical training affects the structure and function of different brain areas, how those areas communicate during the creation of music, and how the brain interprets and combines sensory information. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. These views suggest potential new roles for musical training including training plasticity in the brain, offering an alternative tool in education, and treating a range of learning disabilities. Today's new findings show that long-term high level musical training has a broader effect. Researchers found that musicians have a better ability to combine sensory information from hearing, touch, and sight. The age at which musical training begins influenced brain structure and its function. Beginning training before the age of seven has the greatest effect. Even older adults who took music lessons as children but haven't actively played an instrument in decades have a faster brain response to a speech sound than those who never played an instrument, according to a study appearing November 6 in the Journal of Neuroscience. The finding suggests early musical training has a lasting, positive effect on how the brain deals with sound. "Playing a musical instrument is a multi-sensory and motive experience that creates emotions and movements--from finger tapping to dancing -- and engages pleasure and reward systems in the brain. It has the potential to affect brain function and structure when done over a long period of time," said Gottfried Schlaug, MD, PhD, of Harvard Medical School, press conference speaker, also an expert on music. "As today's findings show, musical training brings about new processes within the brain, at different stages of life, and with a range of effects on creativity, cognition , and learning," he added. Question: The best title of the passage should be _ . - Older People and Musical Training - Musical Training Affects Brain Structure and Its Function - Long-term High Level Musical Training - Brain Interprets and Combines Sensory Information

Read the following article and select the best answer. Article: The English language is the result of the invasion of the island of Britain over many hundreds of years.The first invasions were by a people called Angles about 1, 500 years ago. The Angles were a German tribe who crossed the English Channel . Later two more groups crossed to Britain. They were the Saxons and the Jutes. Through many years, the Saxons, Angles and the Jutes mixed their different languages. The result is what is called Anglo-Saxon or old English. The next great invasion of Britain was done by Vikings about 1, 100 years ago. Many English words used today come from these ancient Vikings. The next invasion of Britain took place more than 900 years ago, in 1066. History experts call this invasion the Norman Conquest. The Normans were a French-speaking people from Normandy in the north of France. These new rulers spoke only French for several hundred years. It was the most important language in the world at that time. It was the language of educated people. But the common people of Britain still spoke old English. Old English took many words from the Norman French. Some of these include "damage", "prison", and "marriage". The French language used by the Norman rulers greatly changed the way English was spoken 800 years ago. English became what language experts call Middle English. Middle English sounds like Modern English. But it is difficult to understand now. The history of the English language continues as Middle English becomes Modern English, which is spoken today. Question: How many groups of invaders are mentioned in the passage? - Three. - Four. - Five. - Six.
