Input: Read this: The expansion of the Rus' put further military and economic pressure on the Khazars, depriving them of territory, tributaries, and trade. In around 890, Oleg waged an indecisive war in the lands of the lower Dniester and Dnieper rivers with the Tivertsi and the Ulichs, who were likely acting as vassals of the Magyars, blocking Rus' access to the Black Sea. In 894, the Magyars and Pechenegs were drawn into the wars between the Byzantines and the Bulgarian Empire. The Byzantines arranged for the Magyars to attack Bulgarian territory from the north, and Bulgaria in turn persuaded the Pechenegs to attack the Magyars from their rear. Boxed in, the Magyars were forced to migrate further west across the Carpathian Mountains into the Hungarian plain, depriving the Khazars of an important ally and a buffer from the Rus'. The migration of the Magyars allowed Rus' access to the Black Sea, and they soon launched excursions into Khazar territory along the sea coast, up the Don river, and into the lower Volga region. The Rus' were raiding and plundering into the Caspian Sea region from 864, with the first large-scale expedition in 913, when they extensively raided Baku, Gilan, Mazandaran and penetrated into the Caucasus.
Question: What year did the Rus raid Baku, Gilan,Mazandaran, and Caucasus?

Output: 913


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: Who was responsible for the segregation of the army?

Output: unanswerable


Input: Read this: These patterns of discrimination against non-whites have led some academic and other activists to advocate for use of the Portuguese term negro to encompass all African-descended people, in order to stimulate a "black" consciousness and identity. This proposal has been criticized since the term pardo is considered to include a wide range of multiracial people, such as caboclos (mestizos), assimilated Amerindians and tri-racials, not only people of partial African and European descent. Trying to identify this entire group as "black" would be a false imposition of a different identity from outside the culture and deny people their other, equally valid, ancestries and cultures. It seems a one-drop rule in reverse.
Question: What would scholars like the term "Negro" to include?

Output: all African-descended people
