1)If both income and substitution-effects are strong, this region of the demand curve
 must be
a) relatively price elastic
b) relatively price inelastic
c) perfectly inelastic
d) unit elastic

2) Two countries with given quantities of labour and capital can produce only two
commodities and can trade only with each other. Country A can produce 10 tons of
coal or 10 tons of steel, but country B can produce only 8 tons of coal or 5 tons of
steel.
Assuming constant costs, Country B should:  
a) import coal and export steel  
b) export coal and import steel
c) export both coal and steel
d) import both coal and steel
 
   
3) The concept of “marginal utility” was introduced by
 a) William S. Jevons
 b) Adam Smith
 c) Antoine A. Cournot
 d) None of the above  
   
4)Which of the following statements is not true?
a) Population principle states that cloning the entire population and their incomes
should not alter inequality.
b) Two Lorenz curves may cross sometimes  
c) Income gap ratio is a measure of inequality
d) Lorenz curve displays cumulative shares of income earned by cumulatively
increasing fractions of the population arranged from poorest to richest

5)In the IS curve, consumption, government expenditure, exports, and imports are a
function of

 a) expectations.

 b) current output.

 c) potential output.

 d) the interest rate.

2.b) export coal and import steel.
4.a) Population principle states that cloning the entire population and their incomes
should not alter inequality.

Also for 5th If logically look at question it should be b).current output coz we all aware that IS cuvre determine short run equilibrium in good market...And  consumption, government expenditure, exports, and imports also depends on current output or current income...
