I'm taking a test and have to guess the right answer to the question after the article. Article: Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into a physical object.This is now possible with the help of 3D printers.Such machines were once used just by universities and big companies.But now, stores with 3D printing services are appearing around the United States. Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago.The store is filled with tools like a laser cutter, an industrial sewing machine and 3D printers.Bryan Jaycox requires $ 15 an hour to print an object.He also charges a fee depending on the size of the object and up to $ 50 an hour for design and labor services. The Jaycoxs also offer 3D printing classes for anyone who is interested.One of the students in a recent class was Ki Chong Tran.He plans to open a 3D printing business in Cambodia."The demand has been amazing.It's been much more than I would have imagined," said Ki Chong Tran. "I think 3D printing is going to be huge. It's going to make a huge impact on society as a whole," he added. Mr Jaycox predicts that within five years, 3D printing technology could become more consumer friendly. But Ki Chong Tran says even current technology can make a difference in a developing country like Cambodia."With 3D printing you can give them tools, and you put it in their hands so they are responsible more for their own development. They learn skills beyond just learning English and becoming a tour guide or something like that or working at a bank.You can actually create things that give value to the world," said Ki Chong Tran. He says it's not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality. Question: In Mr Jaycox's opinion, within five years 3D printing will _ . Options: A: make it easier to do business B: be accessible to all consumers C: change the way of social contact D: bring about more profits to the sellers

I'm taking a test and have to guess the right answer to the question after the article. Article: At a few minutes past five, Dave noted that the blanket of darkness was lifting. He was just able to make out the heavier masses that eventually appeared as the familiar trees that lined the road at the base of the hill. The upper reaches of the sky showed lighter shades of gray. Dave got out of bed quietly and dressed quickly. He mixed a spoonful of instant chocolate into a glass of cold water, and his impatience forced him to finish the drink in gulps. As he walked down toward the lake, Dave paused to reach for the fishing pole and gear box on the bench where he had left them the night before. By the time he reached the small boat, a thick white mist had spread over the surface of the water. He stepped into the boat, sat down, and rowed out of the weed beds that lined the edge of the shore. The outer fringe of the lake disappeared as the boat moved forward noiselessly. All he could see was the enveloping whiteness. He could not tell where the boat and the surrounding air met the surface of the lake. Dave rowed steadily ahead, relying on a mental picture of the surroundings. Then the mist began to rise, slowly. _ soon rested inches above the still surface of the lake. The heavy silence was now being broken by the fish breaking through the surface as they leaped out of the water for low-flying insects. The magic time had arrived. Dave raised his pole. Dawn was broken. He was excited with expectancy. Question: According to the story, which of the following is TRUE? Options: A: Dave broke the quietness of the lake. B: Dave was familiar with the surroundings. C: Dave took a picture of the lake with him. D: Dave forgot the fishing pole at the beginning.

I'm taking a test and have to guess the right answer to the question after the article. Article: I've tried to explain compound interest to my eight - year - old daughter. When I have finished it, she summarizes back to me, "So, you are saying if I put $ 100 in the bank, when I turn sixteen the bank will give me $ 200?" She has already grasped more of the concept than I understood at her age, but she couldn't clearly understand that until she sees them in action. One day I gave her a Ziploc bag with a handful of pennies and told her over the course of a week I wanted her to give me a penny a day. I would deposit the penny in " The Bank of Dad" and compound interest would begin to accumulate the day she deposited the penny. At the end of the week we would check her bank balance. Each day my daughter handed over one penny at the breakfast table and I deposited it in her bank. I gave her a "receipt" for her deposit and explained that she needed to keep up with the receipts to see how much money she had added to her account. In an effort to make this a little more realistic, I deposited a penny from my own piggy bank every other day to give her an additional four pennies at the end of the week. On Sunday evening we gathered receipts and confirmed she had deposited seven pennies in "The Bank of Dad. " Then I opened the old film container and counted out its contents--all eleven pennies. "Hey, there are four extra pennies in there!" I explained that her original seven pennies had grown to eleven pennies because every couple days the bank paid her a penny for letting them use her money--that's interest. She paused and asked, "Dad, what would happen if you deposited like a hundred million pennies in the bank? Question: Which of the following would be the best title for the text? Options: A: How to Deposit Pennies in "The Bank of Dad". B: Welcome to Deposit Money in the Bank. C: How to Teach Compound Interest to Kids. D: A Good Relationship between Father and Kid.
