Read the following article and answer the question. Article: A mansion  may symbolize the American dream. But the fact is, for most immigrants, the closest one they ever get to is the neighboring bushes.     Such is the case with 63-year-old Catalino Tabia, Calif. He's a gardener with a 6'h grade education. He came to America to make his dreams come true, but ended up fulfilling everyone else's."I always wanted to be somebody," Tabia said."But now I just want the opportunity to help others."     That is why, not long ago, Tabia started the Bay Area Gardeners Foundation. It's a charity aiming at helping smart kids like Noel Chavez, whose dream was to become the first in his family to graduate from college.Unfortunately, since Noel is still waiting for his citizenship, he's not qualified for financial aid.And after just a few months of going to school full-time and working full-time, he was ready to give in.     "I'm working too much. I'm not going to do it. It's impossible. But then you get some help, and that's my break. "  The break was a  $  1,500 scholarship from the Gardeners Foundation. In the last two years, the foundation has awarded 13 such prizes to low-income kids, regardless of citizenship. And Tabia plans to give out hundreds more.     How does a gardener come up with that kind of cash?  "I was thinking and thinking and suddenly, the clients V " he said."That's where the money is coming from. We work for clients with a lot of money. " Tabia and his gardener friends just started knocking on those mansion doors-and the checks have been rolling in ever since.  "There might be some gardeners at your graduation," someone said to Noel."I'm sure there will and I'm going to invite them," he replied.     Tabia is now hoping this idea catches on with the gardeners around the country. And whether that happens or not, and whether he realizes it or not, Tabia has already finished what he came to America to do-become somebody. Question: What do we know about Noel? Answer:
****
A: He will invite gardeners to attend his graduation ceremony.

Read the following article and answer the question. Article: The koala  is possibly one of the best known Australian animals, and is found in four states: Queensland, New South Wales, Victoria and South Australia. The word "koala" comes from an Australian aboriginal word meaning "no drink". Sometimes people call them "koala bears" but koala is not a bear. It belongs to a special group of Australian mammals, called marsupial . Female marsupials have a _ where the baby animals live after they are born. Koalas have soft, thick, grey or brown fur on their backs. The fur on the stomach is white. Koala that live in the south have thicker fur than those in the north because of the cold winters, whereas the koalas in the northern part of the country live in warm to hot weather most of the year so have thinner fur. A koala has a large hairless nose and round ears. Koalas don't have tails. Adult koalas measure between 7 and 14 kilograms. Koalas spend nearly all their time in the trees using their sharp, curved claws and long toes to climb about and to hold on to the tree branches. They sleep most of the day, and feed and move from tree to tree mainly at night. The reason koala sleep for much of the day is because their food eucalyptus  leaves are very tough so they use a lot of energy to digest. Sleeping saves energy. Eucalyptus leaves are poisonous to almost every other animal. Koalas rarely drink water; they get water from the leaves they eat. Each koala has a home range made up of several trees that they visit regularly. They normally do not visit another koala's home trees except that a male is looking for a female to mate with. Question: Why do the koalas live in the south have thicker fur than those in the north? Answer:
****
A: The thicker fur can protect them from the colder weather

Read the following article and answer the question. Article: The massive magnitude  8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.  These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake. Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved. The quake's epicenter  was in a region of South America that's part of the so-called "ring of fire," an area of major seismic  stresses which encircles(,) the Pacific Ocean. All along this line, the plates on which the continents move press against each other. Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP. Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes. "We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused." said Brooks.
