Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Before the mid 1860's, the impact of the railroads in the United States was limited, in the sense that the tracks ended at this Missouri River, approximately the center of the country. At the point thetrains turned their freight, mail, and passengers over to steamboats, wagons, and stagecoaches. This meant that wagon freighting, stage coaching, and steam boating did not come to an end when the first train appeared; rather they became supplements or feeders. Each new "end of track" became a center for animal drawn or waterborne transportation. The major effect of the railroad was to shorten the distance that had to be covered by the older, slower, and more costly means. Wagon freighters continued operating throughout the 1870's and 1880's and into the 1890's. Although over constantly shrinking routes, and coaches and wagons continued to crisscross the West wherever the rails had not yet been laid. The beginning of a major change was foreshadowed in the later 1860's, when the Union Pacific Railroad at last began to build westward from the Central Plains city of Omaha to meet the Central Pacific Railroad advancing eastward from California through the formidable barrier of the Sierra Nevada. Although President Abraham Lincoln signed the original Pacific Railroad bill in 1862 and a revised, financially much more generous version in 1864, little construction was completed until 1865 on the Central Pacific and 1866 on the Union Pacific. The primary reason was skepticism that a Railroad built through so challenging and thinly settled a stretch of desert, mountain, and semiarid plain could pay a profit. In the words of an economist, this was a case of "premature enterprise", where not only the cost of construction but also the very high risk deterred private investment. In discussing the Pacific Railroad bill, the chair of the congressional committee bluntly stated that without government subsidy no one would undertake so unpromising a venture; yet it was a national necessity to link East and West together. Question: What can be inferred about coaches and wagon freighters as the railroad expanded? Options: A: They developed competing routes. B: Their drivers refused to work for the railroads. C: They began to specialize in private investment. D: There were insufficient numbers of trained people to operate them.
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: If your child has mobile internet access, it will be more difficult to monitor and control his or her internet use. Kids are turning to the internet for everything from hanging out with friends to shopping, which makes it harder for parents to keep track of their online activities. Fortunately, there are many choices for controlling what your kids see on their computers, laptops, and mobile devices. Content blockers and filters are great tools to use for younger kids. They allow you more control over where they go and what they do online. A content blocker can block some unhealthy websites or limit a child's search to the kind of sites. A content filter can scan sites and pictures and block those sites that contain certain words, key phrases, or content. Consider tracking software for older teenagers. This software enables you to see which sites your children have visited, tracking their path online. This tool gives young people more freedom to explore the Internet, but it also allows you to check that they are using the internet responsibly. Let your teenagers know that you trust them, but that you will be regularly checking that they are visiting appropriate sites online. Even if you use content blockers, filters, and trackers, you know that a lot of kids figure out ways to get around these, so it's important to remain alert . Remember that not all adult sites can be identified by blocker, filter, or tracker software. That's why it's important to talk to your kids about what to do when something inappropriate or scary comes up. Nothing can replace involvement and supervision by adults. Keep monitoring how your kids use the internet on a regular basis without getting into the role of internet traffic police. Question: _ is the most important for parents to monitor and control kid's internet use? Options: A: Tracking software B: Content blockers and filters C: Filters and trackers D: Involvement and supervision by adults
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Studies show that laughter is something that makes you feel calm or relaxed for both physical and psychological wounds though it may seem futile to laugh in the face of pain and fear. When Dan Rather interviewed comedian Bill Cosby just one week after his son, Ennis, was killed, Cosby said, "I think it is time for me to tell people that we have to laugh. You can turn painful situations around through laughter. If you can find humor in anything, you can survive it." Call it a flashlight for dark times: laughter just seems to adjust attitude better than anything else. Inspirational speaker Steve Rizzo recalls a TV interview with an injured firefighter a few days after 9.11.The man had fallen more than 30 stories in one of the towers and had broken a leg. Everyone was crying, and the reporter asked, "How is it that you've come out of this alive?" He looked at her and without missing a beat, said, "Look, lady, I'm from New York and I'm a firefighter; that' all you need to know." "Everyone laughed and though the laughter was only a couple of seconds," says Rizzo. "Sometimes that's all you need to catch your second breath. Laughter gives you that couple of seconds. You're sending a message to your brain, and the message is: If you can still laugh even a little among the pain, you are going to be OK." Of course, there is a difference between laughing off a serious situation and laughing off the fear that results. The firefighter was doing the latter, states Rizzo, the author of Becoming a Humorous Being, and so should we. "If there is anything we have learnt from 9.11, it's how precious life really is," she says. "We have to send a message that our spirit won't die. One important thing that unites us is our ability to laugh." Question: From the passage, we can know that Americans are_. Options: A: really inspired after 9.11 B: hardly united after 9.11 C: nearly surprised by 9.11 D: greatly hurt by 9.11
A: D
