[EX Q]: Question: How long had Shumilov been in the military when the Soviet invaded Poland? Passage 1:Colonel (promoted to Major General 4 June 1940) Mikhail Shumilov took command in April 1938. In September 1939, the corps fought in the Soviet invasion of Poland as part of the 10th Army. It included the 6th, 33rd, and the 121st Rifle Divisions at the beginning of the invasion on 17 September. By 2 October, these divisions had transferred to other units, and it included the 29th, 64th, and 145th Rifle Divisions instead. The corps headquarters relocated to Grodno in November and became part of the 11th Army. Between June and July 1940 it was briefly headquartered at Kovno before moving to Šiauliai in August, part of the Baltic Special Military District. The 11th transferred to the 8th Army in October, and included the 11th and 125th Rifle Divisions by the outbreak of the war. It defended a 40-kilometer sector on the left flank of the 8th Army, with its headquarters in the forests northwest of Skaudvilė. The 125th Rifle Division was in the corps' first echelon, holding covering the highway and railroad from Tilsit to Šiauliai. The 48th Rifle Division (part of the adjacent 10th Rifle Corps), after moving forward from Riga, was to take up positions on the left of the 125th. The corps' 73rd Corps Artillery Regiment included four battalions of 107 mm guns.
 Passage 2:Hardstone carving falls under the general category of glyptic art, which covers small carvings and sculpture in all categories of stone. The definition in this context of "hardstone" is unscientific and not very rigid, but excludes "soft" stones such as soapstone (steatite) and minerals such as alabaster, both widely used for carving, as well as typical stones for building and monumental sculpture, such as marble and other types of limestone, and sandstone. These are typically not capable of a fine finish in very small carvings, and would wear in prolonged use. In other contexts, such as architecture, "hard stone" and "soft stone" have different meanings, referring to actual measured hardness using the Mohs scale of mineral hardness and other measures. Some rocks used in architecture and monumental sculpture, such as granite, are at least as hard as the gemstones, and others such as malachite are relatively soft but counted as hardstones because of their rarity and fine colour.
 Passage 3:Vann stirred up controversy and 10,000 new readers by hiring George Schuyler in 1925, whose editorials and opinions made him famous as the "black H.L. Mencken" (who was a Courier subscriber). Under Vann, the Courier also worked as a tool for social progress. Most significantly, the paper extensively covered the injustices on African Americans perpetrated by the Pullman Company and supported the Brotherhood of Sleeping Car Porters. Vann wrote to gain support for causes such as improved housing conditions in the Hill District, better education for black students, and equal employment and union opportunities. However, Vann often used his Courier editorials to publicly fight with the National Association for the Advancement of Colored People (NAACP) and W. E. B. Du Bois over issues such as President Calvin Coolidge's grants of clemency to black soldiers involved in the Houston Riot and Vann's allegations that James Weldon Johnson embezzled money for personal use from the NAACP and the Garland Fund. This disharmony was resolved in 1929 by published apologies by Vann, Du Bois, and Johnson, and within the decade, Du Bois became a regular Courier contributor. But in 1938, Vann's Courier ended up at odds with the NAACP once again. Vann, through national campaigns and contact with President Franklin D. Roosevelt pursued inclusion of African-American units in the United States Armed Forces. Vann saw this as an achievable step on the path to integration of the military, but the NAACP leadership, primarily Walter White, publicly disagreed with this half-measure, despite the protests of Thurgood Marshall. As a result of the Courier′s influence and Vann's political clout, New York Congressman Fish successfully added an amendment prohibiting racial discrimination in selection and training of men drafted to the Selective Training and Service Act of 1940.
