问题         On July 20, 1969, Neil Armstrong became the first person to walk on the moon. The spacesuit Armstrong wore on his mission has come to symbolize courage and human achievement. In 1971, the Smithsonian’s National Air and Space Museum (NASM) acquired Armstrong’s suit. It stood proudly on display for visitors to admire, until there were changes in the suit’s appearance. "Over time, the suit started to show signs of deterioration(变坏)." Lisa Young says. She works at NASM and her job is to preserve historical and cultural treasures.
        Plastics are tricky to preserve. They tend to degrade (降解) over time. Neoprene is one type of plastic in Armstrong’s suit. The material can turn brittle and break into tiny pieces. This would ruin the spacesuit. NASM, seeking ways to preserve this historical treasure, removed it from display in 2006.
        Yet history can still be saved. Sunlight, water, humidity, and dust can cause plastics to degrade. Scientists have found that storing plastics in cooler temperatures, with lower humidity levels, can slow degradation. Young says Armstrong’s suit is currently in storage at a temperature of 63°F and a lower relative humidity of 30%. These conditions will be maintained when Armstrong’s suit returns to a museum display case in time for this year’s 50th anniversary (周年纪念日) of the moon landing.
        Plastic degradation affects art, too. Artist Claes Oldenburg created False Food Selection in 1906. It consists of plastic food displayed in a wooden box. The plastic food used to look real. Now, some of it has flattened and yellowed. The artwork’s wooden box produces an acidic gas that eats away at the plastic, which speeds up the degradation process. But Young is motivated to preserve this artwork and others like it. "Plastics are a part of our history," she says, "it’s important to preserve them so that future generations can understand the journey we’ve taken." [br] According to the passage, which of the following statements is NOT TRUE?
选项 A、Sunlight, water and dust contribute to plastic degradation.
B、Armstrong’s spacesuit is currently on public display at NASM.
C、NASM acquired Armstrong’s spacesuit in 1971.
D、Claes Oldenburg is an artist.
答案 B
解析 细节题。根据文章第三段第二句“Sunlight, water, humidity, and dust can cause plastics to degrade.”可知，阳光、水、湿度和灰尘都能够降解塑料，A项正确。根据文章第一段第三句 “In 1971, the Smithsonian’s National Air and Space Museum ( NASM ) acquired Armstrong’s suit.”可知，NASM在1971年收购了阿姆斯特朗的宇航服，C项正确。根据文章第四段内容可知，D项正确。根据文章第二段后最后一句“…NASM, seeking ways to preserve this historical treasure, removed it from display in 2006.”可知，2006年宇航服已经从博物馆展厅中移出以寻求更好的保存方法。B项“阿姆斯特朗的宇航服最近在NASM展览”表述错误，故选B。
