Answer 1

You need to understand these concepts (elastic/inelastic demand etc). To answer these questions :-
1) Draw an elastic demand curve
2) Draw an inelastic demand curve
3) Apply each of the alternative answers to the various questions.
4) Put yourself in the situations suggested by some alternatives - an economy is just a collection of individuals. eg, if the price of something fell would you buy much more (eg bread - how much can you eat?).
