Article: BERLIN (AP)----A tiger escaped its enclosure at Cologne Zoo in western Germany on Saturday and killed a female keeper before being shot dead by the zoo's director, police said. The tiger slipped through a passage between the enclosure and a neighboring storage building, where it fatally attacked the 43-year-old keeper, said police spokesman Stefan Kirchner. "It appears the gate wasn't properly shut," Kirchner told The Associated Press. The zoo was evacuated and a SWAT team was called in, police said.But before it arrived, the zoo's director managed to kill the tiger by climbing onto the storage building and shooting it through a skylight using a rifle. Kirchner said it was unlikely that members of the public had witnessed the incident. "This is the darkest day of my life," the zoo's director, Theo Pagel, was quoted as saying by Cologne newspaper Express. The paper said on its website that the Siberian tiger was a 4-year-old male called Tltai that came to Cologne Zoo from an animal park in England.In November it fathered three cubs with a 7-year-old Siberian tiger called Hanya, according to the zoo's website. Police said the zoo reopened after Saturday's incident, which occurred around noon.However, a planned late-night opening of the zoo has been canceled. Cologne Zoo is one of the oldest in Germany.It was founded in 1860 and houses some 10,000 animals consisting of more than 700 different species. Question: What did the zoo do after the incident?

Read the article and select the best answer. Article: Robert Spring, a 19th century forger , was as good at his profession that he was able to make his living for 15 years by selling false signatures of famous Americans. Spring was born in England in 1813 and arrived in Philadelphia in 1858 to open a bookstore. At first he make some money by selling his small but genuine of early U.S. autographs . Discovering his ability at copying handwriting, he began imitating signatures of George Washington and Ban Franklin and writing them on the title pages of old books. To make less the chance of detection , he sent his forgeries to England and Canada for sale and circulation . Forgers have a hard time selling their products. A forger can't approach a respectable buyer but must deal with people who don't have much knowledge in the field. Forgers have many ways to make their work look real. For example, they buy old books to use the aged paper of the title page, and they can treat paper and ink with chemicals. In Spring's time, right after the Civil War, Britain was still fond of the Southern states, so Spring invented a respectable maiden lady known as Miss Fanny Jackson, the only daughter of General "Stonewall" Jackson. For several years Miss Fanny's economic problems forced her to sell a great number of letters and manuscripts belonging to her famous father. Spring had to work very hard to satisfy the demand. All this activity did not prevent Spring from dying in poverty, leaving sharp-eye experts the difficult task of separating this forgeries from the originals. Question: Why did Spring sell his autographs in England and Canada? Options: A: There was a greater demand there than in America. B: There was less chance of being detected there. C: Britain was Spring's birthplace. D: The price were higher in England and Canada.

Many people believe that tension and stress can cause your hair to lose its color.In fact,it is an old wives tale that being upset all the time can result in premature graying.Here is a closer look at this situation and why some believe that this old wives tale could be true. As one ages,the hairs on the head also age.In fact,just about everything on the human body begins to show signs of wear and tear after a while.The joints wear and become stiff and skin wears and becomes wrinkled.Hairs on the head grow and eventually die.They are replaced,but in the process something else happens. When new hairs are replaced,the color or pigment is also added to them.However,as one ages,this pigment becomes less and less available.At first,hairs will have a limited amount of pigment and they will appear to be grayish in color.In time,they will lose all of their pigment and will be white.Many things are known to cause graying.and genetics is a very powerful factor.If one of your parents turns gray at an early age,there is a good chance that you will too.Some people begin the graying process in high school,while others may be over the age of forty. Constant worry and tension can have many harmful effects on the human body.It is a known fact that stressful times can cause one to suffer hair loss.It would make sense that if it can cause these problems,perhaps it also may contribute to graying.However,there is no sound evidence to support this. On the other hand,many medical professionals believe that there may be a link:between graying and a constant state of anxiety or tension.Does stress cause gray hair? There is no scientific evidence to support the theory,but it is best to avoid stressful situations. Question: What might play the most important role in the graying process? Options: A: Genetics and the amount of sleeping time B: The amount of food people eat and living environment C: The amount of pigment and genetics D: Genetics and the amount of water people drink
