The first is called the "tank test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构) of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger. The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines(发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot's job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers. By doing the "tank test", the engineers can find out______. A．the amount of air in the plane B．the strength of the plane structure C．the pressure inside and outside the plane D．the power of the airplane engines

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)
