Article: Grey clouds move as low as smoke over the treetops at Lolo Pass. The ground is white. The day is June 10.It has been snowing for the past four days in the Bitterroot Mountains.Wayne Fairchild is getting worried about our trek over the Lolo Trail-95 miles from Lolo Montana to Weippe in Idaho, across the roughest country in the West. Lewis and Clark were nearly defeated 200 years ago by snowstorms on the Lolo.Today Fairchild is nervously checking the weather reports.He has agreed to take me across the toughest,middle section of the trail. When Lewis climbed on top of Lemhi Pass,140 miles south of Missoula,on Aug.12,1805,he was astonished by what was in front of him;"high mountain chains still to the West of us with their tops partially covered with snow."Nobody in what was then the US knew the Rocky Mountains existed,with peaks twice as high as anything in the Appalachians back East. Today their pathway through those mountains holds more attraction than any other ground over which they traveled,for its raw wilderness is an evidence to the character of two cultures:the explorers who braved its hardships and the Native Americans who prize and conserve the path as a sacred gift. It remains today the same condition as when Lewis and Clark walked it. The Lolo is passable only from July to mid-September.Our luck is holding with the weather,although the snow keeps getting deeper.As we climb to Indian Post Office,the highest point on the trail at 7,033 ft,we have covered 13 miles in soft snow,and we hardly have enough energy to make dinner.After a meal of chicken,I sit on a rock on top of the ridge .There is no light visible in any direction,not even another campfire.For four days we do not see another human being.We are occupied with the things that mix fear with joy.In our imagination we have finally caught up with Lewis and Clark. Question: Judging from the text,Lewis and Clark were most probably _ . Yes or no, is the answer "explorers of the early 19th century"?
No

Article: Imagine that you are on a jury and you hear the testimony of an eyewitness who says that the accused person is guilty. You would probably vote to _ don't you think? Well, more often than not, you'd be wrong. A few years ago, an experiment was done on an evening news show on WNBC in prefix = st1 /New York. Viewers were shown a film of what seemed to be a mugging. In this simulation, a man snatched a woman's purse. He then knocked her down and ran face forward at the camera so that the viewers got a good look at him. Viewers were then shown a lineup of six men. They were asked to decide if the mugger was in the lineup and, if so, to tell which one he was. In effect, then, they had seven choices. The suspect was either one of the six or he wasn't even in the lineup. Of the 2,145 people who called up to respond, 1,843 were wrong. That means about one in seven was right. This is what you'd expect from random choice. Eyewitness accounts can be the most convincing evidence presented to a jury. Yet we are finding out that such accounts can be faulty. Something is just wrong. Why is this so? Recent findings have removed doubts on whether memory can last long. We also know that it can be changed by things such as leading questions. Mistaken eyewitness accounts are common. They are also the major cause of innocent persons being convicted in the United States. Question: What is the passage mainly about? Yes or no, is the answer "Eyewitness accounts can be wrong."?
No

Article: The first time I went for a walk around my father-in-law's neighborhood was garbage day, and I was shocked to see what people were throwing out. It was back in 1981, and I saw many people gathered in someone's front yard. As I went nearer to see what was happening I got my first introduction to yard sales. For the few dollars I had in my wallet, I was able to buy a seven-inch black-and-white portable TV. I also bought a flashlight. The following weekend, at another yard sale, I saw a 14-inch color1 TV being sold for almost nothing. I felt I could not miss the offer and bought it. Now I had two sets and couldn't wait to see what else I could afford the next weekend. Spring ended, and by then I had accumulated almost every type of electronic equipment I had always wished to have back home. Then this new idea came to mind. I had heard about a man who traveled back home every few months. He drove a truck filled with boxes of new and used stuff that people were sending to s. So I told my father that I would send as many types of items as I could so that he could start his resale business. Every few months I would gather several boxes of American "junk" --- televisions, toasters, fans, hair dryers, etc. and send them home. As word got out about my father's "trash" market, people all came to buy these things. Three years later, when I visited my family for the first time since leaving home, I learned that many of the families in our neighborhood had a piece of "trash". It proved that I had the responsibility to keep people back home up to date with the latest technology you no longer need.(304words) Question: According to the text, a yard sale is a place where people _ .
