I'm taking a test and have to guess the right answer to the question after the article. Article: Free Fun Guides Free Admission to Hundreds of Museums Sept. 25 What a weekend! This Saturday, Sept. 25, hundreds of U.S. museums are admission free for the Smithsonian's yearly Museum Day. Unlike previous Museum Day celebrations, you must sign up for a free ticket that admits two people to any of the participating museums. That means filling out a form and having the ticket emailed to you. Not bad for a free offer that will give you admission to museums such as the Adler Planetarium in Chicago and the Air & Space Museum in San Diego. Free Books for Kids @ Barnes & Noble! If your kids love to read -- and we hope they do! -- be sure to sign them up for Barnes & Noble's summer reading programs so they can earn a free book! It's easy for kids ages 12 and under to participate. For Barnes & Noble's Passport to Summer Reading program, just download and print out your passport. Read any eight books, make a list of them on the back of the passport and bring it to any Barnes & Noble by September 7. Choose your free book from the list. FREE Night of Theater Across the U.S. in October It's the yearly run of the Free Night of Theater, when hundreds of theaters in 120 U.S. cities give away thousands of tickets to local productions. While the kickoff date is October 15, many of the theaters start releasing their free tickets by Oct.1 or in waves during the month of October for performance dates throughout the month. Ticket seekers are limited to two tickets for one performance. Find your city on the Free Night of Theater Website and check the listings for performances, their dates and their ticket giveaway times and locations. Question: Which of the following shows the similarity between Museum Day and Free Night of Theater? Options: A: They take place once a year. B: The same number of free tickets is given away. C: The tickets can be used in any U.S. city. D: They last for the same length of time.

I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists who try to predict earthquakes have gotten some new helpers recently--animals. That's right, animals. Scientists have begun to understand what farmers have known for thousands of years. Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a Chinese quake in 1975, snakes awoke from their winter sleep early only to freeze to death in the cold air. Cows broke their halters and tried to escape. Chickens refused to enter their cage. All of this unusual behavior, as well as physical changes in the earth, warned Chinese scientists of the coming quake. They moved people away from the danger zone and saved thousands of lives. One task for scientists today is to learn exactly which types of animal behavior predict quakes. It's not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1977, for example, an Arabian horse became very nervous and tried to break out of his enclosure. The Australian horse next to him, however, remained perfectly calm. It's also difficult at times to tell the difference between normal animal restlessness and "earthquake nerves". A zoo keeper once called earthquake researchers to say that his cougar had been acting strangely. It turned out that the cat had an upset stomach. A second task for scientists is to find out exactly what kind of warnings the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can sense tiny changes in air pressure, gravity, or the magnetism of Earth. This extra sense probably helps animals predict quakes. A good example of this occurred with a group of dogs. They were shut in an area that was being shaken by a series of tiny earthquakes. (Several small quakes often come before or after a large one.) Before each quake a low booming sound was heard. Each boom caused the dogs to bark wildly. Then the dogs began...

I'm taking a test and have to guess the right answer to the question after the article. Article: Cut out part of a healthy person's liver and transplant it into a sick person--it sounds like a complicated and dangerous operation , not to mention very expensive. But it is sometimes the only possible cure for a seriously ill patient with liver disease. Until now British scientists have just announced a new stem cell technique, which allows them to grow healthy liver cells outside human bodies. According to the researchers, it could be another five to ten years before the technique can actually be used to help patients with liver disease. However, they say the method might one day replace liver transplants altogether. The study was led by the University of Cambridge and the Welcome Trust Sanger Institute, a British genomics and genetics research institute. It was published in the journal nature on October 12,2011. The researchers took skin cells from a patient with a mutation in a gene called alphal-antitrypsin (a-l). This gene makes a protein that protects our bodies against inflammation . People with changed or damaged alphal-antitrypsin are not able to release the protein correctly from the liver, so the protein is trapped there and eventually leads to liver cirrhosis . Scientists then used an advanced technique to cut away the faulty section of DNA from a stem cell and replace it with a corrected one, according to the journal. The stem cells went on to produce fresh and healthy liver cells with normal protein levels. Scientists put the new liver cells into mice and found that they worked very well. Stem cells are the life source of all other cells in the body. They could transform medicine, providing treatment for blindness, spinal cord injuries and other serous injuries. They could also be used to produce new cells for damaged organs. David Lomas, a Cambridge biology professor who worked on the team, said: "If we can use a patient's own skins cells to produce liver cells that we can put back into the patient, we may prevent the future need for transplantation. " Question: What is the best title of this passage? Options: A: How to transplant liver for patients B: A new way to transplant livers for patients C: The difficulty in curing liver patients D: New life for liver patients
