Ques:Read the following article and select the best answer. Article: Starting in l972,the National Park Service established a policy for forest fires calle Natural Burn.It was acknowledged that some forest fires,such as those caused by lightning were necessary for forests to maintain balanced ecosystems,so the fire should be allowed to burn.However, a big fire in Yellowstone National Park in l988 caused this policy to be abandoned since the fire was initially allowed to burn yet soon out of control.As a result,the fire of l988 destroyed much of Yellowstone,which is America's oldest and most beloved national park.Massive areas of plants were destroyed,and large empty spaces and acres of burned and blackened trees greeted visitors.The rivers and streams were choked with ash,and the ecosystem of the park was changed beyond repair. In addition,great numbers of animals were killed by the fires that bumed out of control. The fires were driven by high winds,moving as many as ten miles a day.Many small animals died in the flames.The fires' rapid advances gave the wildlife little chance to escape. Even today,few of these small forest animals have returned to live in the park. In the years immediately following the fires,the numbers of visitors declined rapidly.No one was interested in seeing a blackened and treeless park on vacation.Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful. But now its reputation as America's wonder is damaged permanently. Question: Why were so many animals killed in the big fire? - Because winds were blown from high places. - Because the animals moved only ten miles a day. - Because the animals lived in lower places. - Because strong winds contributed to the fire a lot.

Ans:Because strong winds contributed to the fire a lot.

Ques:Read the following article and select the best answer. Article: Everybody knows the saying "Two steps forward and three steps back". That described my life pretty well as a single mom. I was raising two teenagers on a teacher's aide's salary. It wasn't nearly enough to cover the bills, so I moonlighted as a waitress. Every time I thought that I had found a solution to my money worries, something would fall through and I would end up feeling worse off than before. The next evening at the restaurant I tried on my apron, wishing I could be home with my kids. I walked up to my first table. Around it was a cheerful older couple. The woman gave me a smile that warmed me. I couldn't help but notice her unusual glass ring. "What a beautiful ring," I said. We chatted for a minute then I took their order and left. When I came back with their drinks, the woman held out her ring. "I would like to give this to you," she said. "Oh, no, I couldn't," I said, embarrassed. She gently placed the ring in my hand and closed my fingers around it. "It's yours," she said. "Please accept it and your things are going to be okay." Right there at their table in the middle of the restaurant I broke down in tears. "Thank you for giving me hope," I said. Long after that night, that sense of peace stayed with me. I knew the right job would come in time. Nine months later it did. I got a better position at another school and I started waitressing at a restaurant where I was allowed to spend more time with my kids. Now in these tough times, I have money worries again, but they don't get me down. I know things will turn out okay. And when I wear that unusual glass ring, I'm reminded I'm not alone. Question: Now the writer's attitude toward her life is _ . - positive - disappointed - proud - worried

Ans:positive

Ques:Read the following article and select the best answer. Article: A three-year independent investigation into the September 11, 2001 attack on the Pentagon has _ new eyewitness evidence which, according to the Southern California-based researchers who conducted the investigation conclusively (and unfortunately), establishes as a historical fact that the violence which took place in Arlington that day was not the result of a surprise attack by suicide hijackers, but rather a military black operation involving a carefully planned and skillfully executed deception." A CNN Reporter at the scene states that there is no evidence that a 757 hit the Pentagon. What hit the Pentagon? A Boeing 757 loaded with passengers and fuel right? Who was on Flight 757? According to the Flight Information there were No Arabs on it. That makes me wonder if Flight 757 actually existed at all. From the pictures and the videos, people can find that there are several doubtful points that need to be taken into consideration, for example the marker line on the grass in the satellite and ground pictures, the different colors of the smoke, the hole which the plane impacted, and the standing pylons . Also, from the comparison of the different pictures, people can find some other strange points. For example, the gear is not the matching one. The wreckage of the plane is not the one from the American Airlines. The glass on the pavement of the pole is another doubtful point. The last thing that need considering is about the collapse. One of the gif video shows the plane impacting the Pentagon. The only problem with this video footage is that it has been altered and can not be fully trusted. These crash photos and videos shown here clearly have been doctored and don't even match the physics of what happened. So where is the real video? It leaves me many questions. Is this a missile? It is a real enigma. Question: What the word " _ " mean in the first sentence? - given in - surrendered - given away - produced

Ans:
produced
