Input: Read this: The United States joined World War II in December 1941 after the Japanese attack on Pearl Harbor. On the European front, U.S. Army troops formed a significant portion of the forces that captured North Africa and Sicily, and later fought in Italy. On D-Day, June 6, 1944, and in the subsequent liberation of Europe and defeat of Nazi Germany, millions of U.S. Army troops played a central role. In the Pacific War, U.S. Army soldiers participated alongside the United States Marine Corps in capturing the Pacific Islands from Japanese control. Following the Axis surrenders in May (Germany) and August (Japan) of 1945, army troops were deployed to Japan and Germany to occupy the two defeated nations. Two years after World War II, the Army Air Forces separated from the army to become the United States Air Force in September 1947 after decades of attempting to separate. Also, in 1948, the army was desegregated by order of President Harry S. Truman.
Question: What month and year did the U.S. join World War II?

Input: Read this: With the release of 16:9 televisions in the mid-1990s, Pioneer and Toshiba decided that it was time to take advantage of this aspect ratio. Squeeze LDs were enhanced 16:9-ratio widescreen LaserDiscs. During the video transfer stage, the movie was stored in an anamorphic "squeezed" format. The widescreen movie image was stretched to fill the entire video frame with less or none of the video resolution wasted to create letterbox bars. The advantage was a 33% greater vertical resolution compared to letterboxed widescreen LaserDisc. This same procedure was used for anamorphic DVDs, but unlike all DVD players, very few LD players had the ability to unsqueeze the image for 4:3 sets, and very few if any 4:3 sets could be set to play them properly either. If the discs were played on a standard 4:3 television the image would be distorted. Since very few people owned 16:9 displays, the marketability of these special discs was very limited.
Question: With what aspect ratio did Squeeze LDs operate?

Output: 16:9-ratio widescreen

Input: Read this: At the turn of the 21st century, a post-punk revival developed in British and American alternative and indie rock, which soon started appearing in other countries, as well. The earliest sign of a revival was the emergence of various underground bands in the mid-'90s. However, the first commercially successful bands the Strokes, Franz Ferdinand, Interpol, Neils Children and Editors surfaced in the late 1990s to early 2000s, as did several dance-oriented bands such as the Rapture, Radio 4 and LCD Soundsystem. Additionally, some darker post-punk bands began to appear in the indie music scene in the 2010s, including Cold Cave, She Wants Revenge, Eagulls, the Soft Moon, She Past Away and Light Asylum, who were also affiliated with the darkwave revival, as well as A Place to Bury Strangers, who combined early post-punk and shoegaze. These bands tend to draw a fanbase who are a combination of the indie music subculture, older post-punk fans and the current goth subculture. In the 2010s, Savages played a music reminiscent of early British post-punk bands of the late '70s.
Question: Which bands disliked dance?

Output: unanswerable

Input: Read this: But by the 1940s, many of Boas' anthropologist contemporaries were active in the allied war effort against the "Axis" (Nazi Germany, Fascist Italy, and Imperial Japan). Many served in the armed forces, while others worked in intelligence (for example, Office of Strategic Services and the Office of War Information). At the same time, David H. Price's work on American anthropology during the Cold War provides detailed accounts of the pursuit and dismissal of several anthropologists from their jobs for communist sympathies.
Question: What did many anthropologists serve in?

Output:
the armed forces
