Prices are rising continuously.The condition is termed one kind 0f inflation, the money supply is becoming inflated so that each unit of it becomes less valuable.People have got used in recent years to higher and higher rates of inflation. What could be bought ten years ago for one dollar now costs well over two dollars. It seems that this rate of inflation is tending to rise rather than to fall.If in the real world our money incomes go up at the same rate as prices,one might think that inflation does not matter.But it does when money is losing value,it lacks one of the qualities of a good money---stability of value.It is no longer acceptable as a store of value;and it becomes an unsuitable standard of deferred payments.Nobody wants to hold a wasting possession,so people try to get rid of money as quickly as possible. Inflation therefore stimulates people spending,and prevents people from saving. Question: According to the passage,if incomes and prices rise together _ Options: A: the business will become better B: money will hold its value C: inflation won't be a problem D: inflation will remain to be a problem

In the 1940's it was a wholesome, specific little community. It was my home and I loved it there; back then I thought I would never leave. My best friend Rose and I used to collectively dream about raising a family of our own someday. We had it all planned out to live next door to one another. Our dream remained alive through grade school, high school, and even beyond. Rose was my maid of honor when I got married in 1953 to the love of my life, Dick. Even then she joked that she was just one perfect guy short of being married, thus bringing us closer to our dream. Meanwhile, Dick aspired to be an officer in the Marines and I fully supported his ambitions. I realized that he might be stationed far away from Jamaica Plain, but I told him I would relocate and adjust. The idea of experiencing new places together seemed somewhat romantic to me. So, in 1955, Dick was stationed in Alaska and we relocated. Rose was sad to see me leave, but wished me the best of luck. Rose and I remained in touch for a few years by regular phone call but after a while we lost track of one another. Back in the 1950's it was a lot more difficult to stay in touch with someone over a long distance, especially if you were relocating every few years. There were no email addresses or transferable phone number and directory lookup services were available at best. I thought of her several times over the years. Once in the mid 1960's ,when I was visiting the Greater Boston area, I tried to determine her whereabouts but my search turned up empty-handed. Jamaica Plain had changed drastically in the 10 years I was gone. A pretty obvious shift in income demographics was affecting my old neighborhood. My family had moved out of the area, as did many of the people I used to know. Rose was nowhere to be found. 52 years passed and we never spoke. I've since raised a family of five, all of whom now have families of their own, and Dick passed away a few... Question: What was the dream of the writer and Rose when young except that _ ? Options: A: They could have a family of their own B: They could marry a promising husband C: They planned to become neighbors D: They could go to the same school

Some scientists are now designing silicon computer chips that act like human organs. The scientists think they have found a way to make the process faster and more economical. The silicon computer chips are smaller than a child's hand. Each one has living cells that act and react like a human organ. The chips are being created as part of a program to test the safety of drug compounds. It is called the Tissue Chip for Drug Screening Program. It is a project of the US National Center for Advancing Tmnslational Sciences, or NCATS. Danilo Tagle is the center's Associate Director. He says a three-dimensional computer chip can be designed to act like a human lung. Some computer chips contain very small models of the human digestive system. They copy the real function or duties of the human stomach and intestine , moving when breaking down food. Drugs are added to the tiny organs for testing through instruments known as micro-tubes. Experiments with the tissue chips have produced more detailed information than tests using animal or cell models. NCATS just announced$17 million in grants to develop an entire human organ system over the next three years. Question: Why are scientists designing silicon computer chips acting like human organs? Options: A: To treat the patients whose body organs don't work well. B: To examine the health condition of human organs. C: To make testing new drugs faster and cheaper. D: .To further study the function of human organs.
