　　C. qualitative rather than quantitative measures of risk.

　　3.The major risk involved with commodity spot transactions that is divided into two areas (ordinary and extraordinary) is:
　　A. Price risk.
　　B. Delivery risk.
　　C. Transportation risk.
　　D. Credit risk.
　　Answer:
　　1.D
　　The bottom-up difference is that the focus is on loss causes rather than just loss indicators. Bottom-up operational risk measures may be either quantitative or qualitative.
　　2.B
　　An arbitrage opportunity exists when a combination of two securities will produce a certain payoff in the future that produces a return that is greater than the risk-free rate of interest. Borrowing at the riskless rate to purchase the position will produce a certain future amount greater than the amount required to repay the loan.
　　3.C
　　Transportation risk is divided into two areas: ordinary (e.g., deterioration, spoilage, accident) and extraordinary (e.g., acts of God, wars, riots, strikes). For example, transportation risk could result from ships lost at sea or train cars overturned.
