I'm taking a test and have to guess the right answer to the question after the article. Article: On the first day of the 11th grade, our new math teacher Mr Washington asked me to go to the blackboard to do a math problem. I told him that I couldn't do it. He asked, "Why not?" I paused, and then I said, "Because I'm educable mentally retarded ." He came from behind his desk and looked at me. "Don't ever say that again. Someone's opinion of you does not have to become your reality," he said. It was a very special moment for me. Doctors said that I was educable mentally retarded in the fifth grade, and I was put back into the fourth grade. When I was in the eighth grade, I failed again. But Mr Washington changed my life. This person always gave students the feeling that he had high expectations of them, and then all of the students did their best to live up to what those expectations were. He often said, "You have greatness within you." One day, I caught up with him in the parking place and said, "Mr Washington, is there greatness within me, sir?" He said, "Yes, Mr Brown." "But what about the fact that I failed in English, math and history? What about that, sir? I'm slower than most kids." "It doesn't matter. It just means that you have to work harder. Your grades don't determine who you are or what you can produce in your life." "I want to buy my mother a house." "It is possible, Mr Brown. You can do that." And he turned to walk away. "Mr Washington?" "What do you want now?" "Uh, I'm the one, sir. One day you're going to hear my name. I'm the one, sir." School was a real struggle for me. Mr Washington put many demands on me. He made me believe that I could do it. At the end of that year, I was on the honor roll for the first time in my life. Years later, I produced five programs on public television. When one of my programs was shown on the educational television channel, I had some friends call him. I was sitting by the phone waiting when he called me. He said, "May I speak to Mr Brown, please?" "Oh, Mr Washington, is that you?" "Yes, it's me. You... Question: In the passage, the author implies that _ . Options: A: people shouldn't believe what doctors say B: no one can be successful with hard work and confidence C: no one is really educable mentally retarded D: a good teacher can change a student's life

I'm taking a test and have to guess the right answer to the question after the article. Article: Brooke Martin's golden retriever Kayla hated being left alone or separated. She would howl, pace, and chew on things. Brooke learned that other people had the same problem with their pets. She wondered: --What if you could talk to your dog if you were gone? Working with her father in their garage, the 16-year-old came up with several ideas. Finally, she invented a device that allowed pet owners to video chat with their pets! She calls the device iCPooch. --The dog doesn't have to answer the call,explains Brooke. --It comes up immediately on the screen on their end. It's a two-way audio and video--you can see and hear each other.With a click of a button you can even send the dog a treat! Her invention has earned her a spot competing against nine other finalists in a young scientist competition for middle-school students. These finalists, selected based on their short video presentations, are working with mentors over the summer before heading to the final competition in St. Paul, Minn. After Martin's video put her among the 10 finalists in the Discovery Education 3M Young Scientist Challenge, she was paired with Delony Langer-Anderson, a product development scientist in 3M's consumer health care division. --I just lead her down the product development path,Langer-Anderson told Live Science. This path includes guidance on how to test the potential product, which combines a video chat device that answers immediately on the dog's end with a dog treat device the owner can remotely activate. One thing I have thought about a lot is, what happens if while the device is on the floor, what if your dog knocks it over, or scratches the screen? Martin said. She and Langer-Anderson discussed this, and Martin is now testing materials at a local dog shelter by taping them to the dog house floors to see how well they withstand sharp teeth and claws. The finalists create models they can test, with the guidance from a mentor. Their projects include a fuel cell that transforms cut grass into electricity and an app that rewards... Question: What do the inventions of the finalists have in common? Options: A: They are all new inventions dealing with pets. B: They are possible solutions to everyday problems. C: They cope with the problems related to computers. D: They are all accomplished through individual work.

I'm taking a test and have to guess the right answer to the question after the article. Article: London-Lazy students can now give up on work altogether as two Oxford University students have made scores of A-grade essays on the website for students to copy. The essays are on the new website, "revise.it" The website includes an "EssayLab" designed to make cheating as effective and effortless as possible. Its homepage announces to surfers : "The revise.it EssayLab is a bank of hundreds of A-Level essays covering popular topics." "Next time you are asked to write an essay, why not see what we have on the subject-if you are in a lazy state of mind you can even use our guide to writing the essays and then just hand them in." Nick Rose and Jordan Mayo, both 19 and first from Manchester, spent much of their first year as students at the university setting up the website. There is no charge for downloading the essays. "I have never been very good at essay writing," Rose admitted. "We don't see essay bank as a cheating way. It's a surprising valuable resource. You can learn a lot by reading other people's work on the subject." Among other tips, the website suggests inventing important speeches to give essays extra weight: "Popular people to quote are Douglass Hurd or Disraeli." Hurd was a foreign secretary in the 1980s and Disraeli was a 19 century prime minister. Teachers are expressing their opinions by e-mail that they are angry about the website that "encourages students to cheat", but students disagree. According to Rose: "Exams are a fight. It's us against them." Question: It can be inferred from this passage that _ . Options: A: students who visit the website "revise. it" are all lazy B: students in Oxford University are all lazy C: websites in Oxford University are all set up by students D: websites can provide people with different kinds of information
