QUESTION 3 3.1. Figure 1а belоw represents the wоrld mаrket fоr nаtural rubber. RIGHT CLICK the button to see Figure 1a Between October 2011 and October 2012, the price of natural rubber decreased by 21%. This fall in price was due to a decrease in world demand for natural rubber. 3.1.1 On Figure 1a, label the new equilibrium curve, D1, to show the decrease in world demand for natural rubber. Labe the new equilibrium Price P1 and quantity Q1 (3) 3.1.2 Identify and briefly explain two factors which may have led to a decrease in the world demand for natural rubber. (4) 3.1.3 Natural rubber is made from the juices inside rubber trees, grown mainly in three Asian countries that have a suitable wet and warm climate: Thailand, Indonesia and Malaysia. It takes seven years for the trees to mature before the juices can be turned into rubber. Rubber supply from plantations in South America has been reduced because many of the trees are diseased. This information shows that the supply of natural rubber is always price inelastic. Do you agree with this statement? Give ONE reason for your answer. (2) 3.2.
