　　NASA quickly refuted these claims in a series of press releases, stating that any photographer would know it is difficult to capture something very bright and very dim on the same piece of film. Since the photographers wanted to capture the astronauts striding across the lunar surface in their sunlit space suits, the background stars were too faint to see.

　　Section A

　　Directions: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words on Answer Sheet 2. Questions 47 to 51 are based on the following passage.

　　Wild ducks and other migratory(迁移的) birds could be important carriers of deadly bird flu, researchers say. Even so, the infectious-disease experts say there is no solid basis for killing wild birds to protect poultry and minimize the risk of human infection.

　　The European team investigating the global spread of the H5N1 strain of avian influenza(禽流感)says certain duck species may be infecting wild bird populations. Geese and wading birds are also possible vectors(带菌者)of the virus, the team says.

　　The team's study was led by Bjrn Olsen of Umea University in Sweden. Olsen runs Europe's largest wild-bird flu monitoring program.

　　Studies have shown that influenza viruses in lake water, generally passed via bird feces(粪), can stay infectious for up to 30 days. The migration or feeding behavior of dabbling ducks could at least partially explain the spread of the H5N1 strain of bird flu, the researchers add.

　　This group of duck species includes mallards, teal, pintails, and others that feed at or near the surface, where viruses in water are most likely to be picked up. Perhaps as a result, dabblers have the highest known rates of avian influenza infection, the study says. For instance, nearly 13 percent of mallards tested positive for bird flu. Other species tested include the American black duck (18.1 percent), blue-winged teal (11.5 percent), and northern pintail (11.2 percent).
