So, are malls one of the highlights of modern civilization? Environmental activists would say No! They would go even further and say that consumer behavior is causing a huge environmental disaster. cause consumers of ignorance of the side effect of their shopping--urban sprawl . Social scientists agree that patterns of development have changed the landscape a great deal in the last half century. Before 1950, most people lived in towns or cities and either walked to work or took public transportation. Only very wealthy people had automobiles. Farmers lived in rural areas or isolated villages and came into town only when they needed things they couldn't produce themselves. If you gazed at the landscape you would see towns surrounded by countryside. Then a massive change occurred. Automobiles became affordable and people were quick to adopt them. Now ambitious workers could live in the suburbs, the areas just outside cities, which started to grow rapidly. As long as there was lots of cheap land in the suburbs, no one paid much attention to the usage of that land. Malls, fast food restaurants, cinemas, and car dealerships spread out in large, flat buildings. These one-storey buildings and their parking lot took up a great deal space. Well- meaning farmers thought they were better off selling their land than growing crops. In ignorance, no one realized that once the land was built up in urban sprawl, the good farming land would be ruined forever. There was no way to preserve it. Only in recent years have people come to mourn the old way of life as they have developed insight into the problems. Now people realize that urban sprawl has come with serious environmental problems. The negative aspects of sprawl include air and water... Question: What do scholars think should be done about urban sprawl? Answer:

Question: Read the following article and answer the question. Article: In the 1950s, a family that owned a farm near Beulah, Michigan kept a bull chained to an elm . The bull paced around the tree, dragging the heavy iron chain, which led to a groove in the bark . The groove deepened over the years. Though for whatever reason, it did not kill the tree. After some years, the family took their bull away. They cut the chain, leaving the loop around the tree and one link hanging down. Then one year, agricultural disaster struck Michigan in the form of Dutch Elm Disease. All of the elms lining the road leading to the farm became infected and died. Everyone thought that the old elm would be the next. The farm owners considered doing the safe thing: pulling it out and cutting it up into firewood before it died. But they simply could not bring themselves to do it. It was as if the old tree had become a family friend. So they decided to let nature take its course. Amazingly, the tree did not die. Nobody could understand why it was the only elm still standing in the county! Plant experts from Michigan State University came out to observe the tree. They observed the scar left by the iron chain, now almost completely covered by bark. The experts decided that it was the chain that saved the elm's life. They reasoned that the tree must have absorbed so much iron from the chain that it became immune to the virus. It's said that what doesn't kill you will make you stronger. Or, as Earnest Hemingway put it, "Life breaks us all, but afterwards, many of us are strongest at the broken places." Question: What actually saved the elm? Answer:
OPTIONS:
- The bull.
- The groove.
- The iron chain.
- The experts.
Answer: The iron chain.
