Read the following article and select the best answer. Article: A big, mighty tree stood in a forest. Its branches spread out and its roots went deep in the earth. A lot of people came here to have a rest under it. And a lot of birds stood on its branches to sing and dance. The big tree was very proud all the time. At the foot of the tree, there was a little plant. The plant was thin, and seemed to be blown down by any of a little wind. One day, the two neighbors were having a little chat. "Well, little one," said the tree to the plant, "why not put your feet deeply in the earth, and raise your head high in the air as I do?" "I see there is no need to do so," said the plant with a smile. "In fact, I think I may be safer in this way." "Safer?" said the tree. "Are you safer than I am? Do you know how deep my roots are in the earth and how strong my branches are? Who can possibly pull me out by the roots or bow my head to the ground?" And the tree didn't want to say anything to the weak plant. But the tree was to regret its words very soon. One evening, a great hurricane came. It blew the trees off their roots and almost destroyed the forest completely. It uprooted(......)the mighty tree and blew it away with great force. When the storm had gone, the villagers living nearby came to check the damage. The mighty tree lay on the ground, but the little plant still stood there. Question: Why was the big tree proud before its neighbor? - Because a lot of people came to have a rest under it. - Because it was tall and thick. - Because a lot of birds stood on its branches to sing and dance. - All of the above.
**Answer**
All of the above.

Read the following article and select the best answer. Article: The world itself is becoming much smaller by using modern traffic and modern communication means . Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it. Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world. Air pollution is still the most serious. It's bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills fish and pollutes drinking water. Noise pollution makes us become angry more easily. Many countries are making rules to fight against pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air. The pollution of SO2 is now the most dangerous problem of air pollution. It is mostly caused by heavy traffic. It is certain that if there are fewer people driving, there will be less air pollution. The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must try to control the growth of population at the same time. Question: Air pollution is the most serious kind of pollution because . - it's bad to all living things in the world - it makes much noise - it has made our rivers and lakes dirty - it makes us become angry more easily
**Answer**
it's bad to all living things in the world
