The first study was done at Duke University in Durham, North Carolina. Researchers pumped extra carbon dioxide into a test area where pine trees were growing. The trees grew thirty-four percent faster during the first three years. However, in time, the trees slowed to about their normal growth rate. The scientists say this is because trees need other nutrients, such as nitrogen. In the second study, researchers from Duke and Bowdoin College in Brunswick, Maine examined the soil around trees. They discovered that as the leaves broke down into the soil, all the carbon was not trapped in the soil. Much of it was released into the atmosphere as carbon dioxide. The findings of the two studies were published last month in Nature magazine. They suggest there is limited value in planting trees to reduce the carbon dioxide pollution in the atmosphere. Forest planting has been a part of negotiations on a world agreement to reduce greenhouse gases that scientists believe cause global warming. The United States, Canada, Japan and some other industrial countries have supported the idea. But this new research suggests the idea is not as effective as environmental activists had thought. Scientist Ram Oren of Duke University led the study on tree growth. He says that earlier estimates on the ability of forests to absorb carbon dioxide were overly hopeful. Some scientists not involved in the studies say the research provides some of the first evidence on how trees react to carbon dioxide. Other scientists say the research disputes a belief among some coal and power companies. The companies say that rising levels of carbon dioxide in the atmosphere will not create harmful global warming. Instead, they say it will increase forests and other plants. What is the purpose of this passage？ A．Introduce some new ideas about the relationship between trees and carbon dioxide. B．Introduce recent condition of global industrial pollution. C．Call on people to plant more trees to reduce greenhouse gases. D．Point out that power companies should be responsible for the rising levels of carbon dioxide.

Chair Co plans on pricing the seat by adding a 50% mark-up to the total variable cost per seat, with the labour cost being based on the incremental time taken to produce the 8th unit. Required: (a) Calculate the price which Chair Co expects to charge for the new seat. Note: The learning index for a 75% learning curve is –0·415. (5 marks) (b) The first phase of production has now been completed for the new car seat. The first unit actually took 12·5 hours to make and the total time for the first eight units was 34·3 hours, at which point the learning effect came to an end. Chair Co are planning on adjusting the price to reflect the actual time it took to complete the 8th unit. Required: (i) Calculate the actual rate of learning and state whether this means that the labour force actually learnt more quickly or less quickly than expected. (3 marks) (ii) Briefly explain whether the adjusted price charged by Chair Co will be higher or lower than the price you calculated in part (a) above. You are NOT required to calculate the adjusted price. (2 marks)
