Use the information in the passage to answer the questions. Influenza, also known as flu, is a highly infectious disease caused by a virus. The virus can be spread by an infected person coughing and sneezing. The incubation period is the time between a person catching a virus and starting to show symptoms. The incubation period for flu is between one and three days. A person can start spreading the virus one day before they start feeling unwell and can continue to pass it on for another three to seven days after. Common symptoms of flu are fever, headaches and aching muscles. Most people recover from flu within a week but some people develop serious complications and require hospital treatment. A vaccination is offered to people who are most at risk from flu, including the elderly and those with chronic heart or lung disease. The flu vaccine, which helps the body fight infection, is given as an injection in the arm. However, the flu virus continually changes and new vaccines must be developed each year. (a) How can the flu virus be spread? ……………………………………………………………………………………………. (b) How long is the incubation period for flu? ……………………………………………………………………………………………. (c) What are the common symptoms of flu? ……………………………………………………………………………………………. ……………………………………………………………………………………………. (d) Which people are most at risk from flu? ……………………………………………………………………………………………. …………………………………………………………………………………………….

Different types of coal have different moisture content (%). The heat output (kW/kg) depends on the type of coal. Anthracite coal has a moisture content of 15%. The heat output of anthracite is 9 kW/kg. Bituminous coal has a higher moisture content of 20% and gives out 7·5 kW/kg. The heat output of lignite coal is 6 kW/kg and it has a moisture content of 30%. Brown coal has the lowest heat output, 5 kW/kg, and at 45%, it has the highest moisture content. Show this information in a table with three suitable headings.
