[单项选择]For most of the past three years, the highly pathogenic bird flu known as HSNI has been found mainly in Asia. Suddenly it has arrived in many countries in Europe, triggering widespread alarm. The detection of the virus in wild birds across Europe is certainly a cause for concern, particularly to Europe’s poultry farmers, who are rightfully worried that the presence of the virus in wild birds will increase the risk to their flocks. However, in the midst of a European debate about the benefits of vaccinating chickens and whether or not poultry should be brought indoors, there is a danger that far more significant events elsewhere will be overlooked.
In particular, most attention should be focused on the fact that bird flu is now widespread in the poultry flocks of two nations in Africa—Egypt and Nigeria—and in India. And on the fact that, in Nigeria, the disease is continuing to spread despite great efforts undertaken by the government. An outbreak in Afghanistan also appears to be
A. Most probably, H5N1 originated in Asia.

[单项选择]During the past 15 years, the most important component of executive pay packages, and the one .most responsible for the large increase in the level of such compensation, has been stock-option grants. The increased use of option grants was justified as a way to align executives’ interests with shareholders’. For various tax, accounting, and regulatory reasons, stock-option grants have largely comprised "at-the-money options": rights to purchase shares at an "exercise price" equal to the company’s stock price on the grant date. In such at-the-money options, the selection of the grant date for awarding options determines the options’ exercise price and thus can have a significant effect on their value.
Earlier research by financial economists on backdating practices focused on the extent to which the company’s stock price went up abnormally after the grant date, My colleagues and I focused instead on how a grant-date’s price ranked in the distribution of stock prices during the month
A. how the company’s stock price went up after the grant date.
B. how stock price distribution influence the rank of granted price.
C. how backdating practices influence the value of stock shares.
