问题：Which three of the following changes in the environment will improve sales for a brewery?
　　A. Tightening of drink driving legislation.
　　B. Tightening of border controls reducing illegal imports.
　　C. Increase in the minimum wage rate.
　　D. Change in tastes from draught to bottled beers.
　　E. Reduction in the legal age for drinking.
　　F. Increased emphasis on healthy living.
　　答案：The correct answers are: Reduction in the legal age for drinking; Increase in the minimum wage rate; Tightening of border controls reducing illegal imports.
　　These will all lead to an increase in legitimate sales. Changes in taste from draught to bottled beers will change the product sales mix but not necessarily change overall sales. The remaining options would tend to reduce sales.
