Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.Swine influenza (also called swine flu, hog flu and pig flu) is an infection of a host animal by any one of several specific types of microscopic organisms called “swine influenza virus”. A swine influenza virus (SIV) is any strain of the influenza family of viruses that is usually hosted by (is endemic in) pigs. As of 2009, the known SIV strains are the influenza C virus and the subtypes of the influenza A virus known as H1N1, H1N2, H3N1, H3N2 and H2N3. Swine influenza is common in pigs in the mid-western United States (and occasionally in other states), Mexico, Canada, South America, Europe (including the UK, Sweden and Italy), Kenya, Mainland China, Taiwan, Japan and other parts of eastern Asia.Transmission of swine influenza virus from pigs to humans is not common and does not always cause human influenza, often only resulting in the production of antibodies in the blood. The meat of the animal poses no risk of transmitting the virus when properly cooked. If transmission does cause human influenza, it is called zoonotic swine flu. People who work with pigs, especially people with intense exposures, are at increased risk of catching swine flu. In the mid-20th century, identification of influenza subtypes became possible, this allows accurate diagnosis of transmission to humans. Since then, fifty confirmed transmissions have been recorded, rarely, these strains of swine flu can pass from human to human. In humans, the symptoms of swine flu are similar to those of influenza and of influenza-like illness in general, namely chills, fever, sore throat, muscle pains, severe headache, coughing, weakness and general discomfort.The 2009 flu outbreak in humans, known as “swine flu’, is due to a new strain of influenza A virus subtype H1N1 that contains genes closely related to swine influenza. The origin of this new strain is unknown. However, the World Organization for Animal Health (OIE) reports that this strain has not been isolated in pigs. This strain can be transmitted from human to human, and causes the normal symptoms of influenza.

Read the passage then choose the correct answer to each question. Circle A, B ,C or D.The play now on at the New Theater as part of the Eastern Arts Festival is not among the best plays for which the director, Army Fielding, has been responsible.The action takes place in the home of Professor Spear. One night his landlady comes to the house for a chat. After inviting her in, the professor hears a sound and thinking it is a burglar coming to rob the house, fires his gun. By mistake the wrong person is shot and the thief gets away. The scene of the second act is a law court, in which everyone waits to find out if the professor is guilty of murder.I did not care for the acting in some cases. Norman Jones is normally seen in some comedies and it is not satisfactory as the professor. He doesn’t look like a wise old man. Also Simon Fry, as the servant, shouted at the top of his voice through the play. The hit of the evening, however, was James Smith as the judge. On the whole, the play appeared to be a little out of date. I can think of many other plays which would have been more suitable for a group of clever young actors to perform. The play continues until the end of the month.
