　　Questions 47 to 51 are based on the following passage.

　　Severe winter storms have worsened the nation’s usual post-holiday blood shortage, prompting an urgent call today for people to donate blood. Type O blood is the most urgently needed, because it is the universal blood type, meaning it can be safely transfused to most people in an emergency. “The severe winter weather has forced the cancellation of blood drives and limited our ability to collect blood,” American Red Cross President Elizabeth Dole said. The Red Cross reported having less than one day’s supply of Type O blood on hand in 18 of the organization’s 38 collection regions. The Red Cross provides about half of the nation’s blood supply. America’s Blood Centers, which supplies most of the rest, also has reported shortages.
