Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34      A little more than a hundred years ago, a number of European scholars began to record stories being told in peasant cottages and compile them into the first great collections of European folk tales. Written evidence exists to prove that the folk tales they recorded existed long before then though. Collections of sermons from the 12th to the 15th century show that medieval preachers knew of some of the same stories as those recorded by the 19th century folklorists.           The collections of folk tales made in the late 19th and early 20th centuries provide a rare opportunity to make contact with the illiterate masses who have disappeared into the pass without leaving a trace. To reject folk tales as historical evidence because they cannot be dated and situated with precision like other historical documents is to turn one’s back on one of the few points of entry into the previous centuries. But to attempt to penetrate that world is to face a daunting set of obstacles, the greatest of which is the impossibility of listening in on the story tellers. No matter how accurate they may be the versions of the tales recorded in writing cannot convey the effects that the storytellers must have used to bring the stories to life: the dramatic pauses, the sly glances, the use of gestures to set scenes, and the use of sounds to punctuate actions. All of those devices shaped the meaning of the tales, and all of them elude the historian. He cannot be sure that the limp and lifeless text he holds between the covers of a book provides an accurate account of the performance that took place in earlier timesWhat do the collections of folk tales made in the late 19th and early 20th provide the historians?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42       Garbage cans are not magical portals. Trash does not disappear when you toss it in a can. Yet, the average American throws away an estimated 1,600 pounds of waste each year. If there are no magic garbage fairies, where does all that trash go? There are four methods to managing waste: recycling, landfilling, composting, and incinerating. Each method has its strengths and weaknesses. Let's take a quick look at each.       Recycling is the process of turning waste into new materials. For example, used paper can be turned into paperboard, which can be used to make book covers. Recycling can reduce pollution, save materials, and lower energy use. Yet, some argue that recycling wastes energy. They believe that collecting, processing, and converting waste uses more energy than it saves. Still, most people agree that recycling is better for the planet than landfilling.       Landfilling is the oldest method of managing waste. In its simplest form, landfilling is when people bury garbage in a hole. Over time the practice of landfilling has advanced. Garbage is compacted before it is thrown into the hole. In this way more garbage can fit in each landfill. Large liners are placed in the bottom of landfills so that toxic garbage juice doesn't get into the ground water. Sadly, these liners don't always work. Landfills may pollute the local water supply. Not to mention that all of that garbage stinks. Nobody wants to live next to a landfill. This makes it hard to find new locations for landfills.       Compositing is when people pile up organic matter, such as food waste, and allow it to decompose. The product of this decomposition is compost. Compost can be added to the soil to make the soil richer and better for growing crops. While composting is easy to do onsite somewhere, like home or school, it's hard to do after the garbage gets all mixed up. This is because plastic and other inorganic materials must be removed from the compost pile or they will pollute the soil. There's a lot of plastic in garbage, which makes it hard to compost on a large scale.       One thing that is easier to do is burning garbage. There are two main ways to incinerate waste. The first is to create or harvest a fuel from the waste, such as methane gas, and burn the fuel. The second is to burn the waste directly. The heat from the incineration process can boil water, which can power steam generators. Unfortunately, burning garbage pollutes the air. Also, some critics worry that incinerators destroy valuable resources that could be recycled.            Usually, the community in which you live manages waste. Once you put your garbage in that can, what happens to it is beyond your control. But you can make choices while it is still in your possession. You can choose to recycle, you can choose to compost, or you can choose to let someone else deal with it. The choice is yoursWhich conclusion could be drawn from the passage?
