Q: Read the following article and answer the question. Article: In jokes, the chicken only crosses the road. In Australia,cane toads use roads to travel. A new study finds that Cane toads are using roads to spread across the continent. They take shelter overnight close to the opencorridors , and then hit the road each evening in their damaging way. Cane toads were brought into Australia from Hawaii in 1935 to control the spread ofbeetles that were destroying Australia's sugar cane crop. _ are now moving into new places at the speed of 30 miles a year. Toads can grow as large as dinner plates and can weigh up to 4.5 pounds. Their heads and backsides are covered with rows ofwarts . They are known to kill snakes, lizards and other animals, including pet dogs. They have no natural enemy in Australia. According to a research, toads make slower progress through thick plants than along open spaces and they hop alongside roads and fences whenever possible. Toads use long corridors that are well-suited for them to travel long distances. Another study recently found that toads haveevolved longer legs in recent years and that this is also helping them in their spread. Efforts to kill toads have been largely unsuccessful, although scientists tried their best. Another new finding suggests ways to slow down its population. For example, roadside borders can be changed to make them less attractive to toads, or allowing thick plants to grow along the sides of highways, thus forcing toads onto the road of themselves. Question: According to the passage, the ways to slow down the population of toads are based on the fact that cane toads _ . Answer: | OPTIONS:
- move slower through thick plants
- have no natural enemy in Australia
- mainly live near the roadside
- like traveling at night
A: move slower through thick plants

Q: Read the following article and answer the question. 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: We learn from the text that before 1805 _ . Answer: | OPTIONS:
- The Rocky Mountains were wholly covered with snow
- there were no people living in the western part of America
- no Americans knew of the existence of the Rocky Mountains
- the Appalachians were the western frontier of the United States
A: no Americans knew of the existence of the Rocky Mountains

Q: Read the following article and answer the question. Article: Many parents take on the role of being their children's preschool teacher and the responsibility of readying them for kindergarten. To achieve this goal, it is important for parents to introduce a variety of subjects in a positive and playful manner. "Learning should not be forced,"says Marion Godwin, who has taught first grade in Moorestown, N. J. for more than 30 years." It should be taught according to what they know and do best--and that is' play'. When teaching them, play games and have fun with the subject. And parents should always be looking for'teachable moments'." "You want a child to be a lifelong learner, so you want to show them learning is everywhere,"she says."If parents take the time to lay a strong educational foundation, their children will keep building on it." Introduce children to science with hands-on activities that interest them, such as growing plants from seeds, discussing animals and how to care for pets, and observing the chemical changes that occur during cooking", she says. "Sorting activities, simple patterns and counting games are a great way to teach children the basics of math, and taking them on field trips, singing songs and reciting rhymes also are ways to prepare them for the first day of school", she says. "I think children are naturals when it comes to computers," she says."Let them play educational games on the computer and teach them how to type their first names using the keyboard. When they are more familiar with using the computer, let them find pictures of animals and places on the web. " "Don't criticize the child," she says. "You can't force them to learn something. If they don't get something right, so what? Smile and be happy and make the experience joyful. Parents need to understand that if a child gets something wrong, they may think something is wrong with them. Keep working with them and when they get the right answer make sure you tell them how hard they worked to get the correct answer. " Question: Marion Godwin tells us that we should teach the children according to their _ . Answer: | OPTIONS:
