Input: Read this: Cotton is used to make a number of textile products. These include terrycloth for highly absorbent bath towels and robes; denim for blue jeans; cambric, popularly used in the manufacture of blue work shirts (from which we get the term "blue-collar"); and corduroy, seersucker, and cotton twill. Socks, underwear, and most T-shirts are made from cotton. Bed sheets often are made from cotton. Cotton also is used to make yarn used in crochet and knitting. Fabric also can be made from recycled or recovered cotton that otherwise would be thrown away during the spinning, weaving, or cutting process. While many fabrics are made completely of cotton, some materials blend cotton with other fibers, including rayon and synthetic fibers such as polyester. It can either be used in knitted or woven fabrics, as it can be blended with elastine to make a stretchier thread for knitted fabrics, and apparel such as stretch jeans.
Question: Besides new cotton fivers, what type of fivers can be used to make elastine?

Output: unanswerable

Input: Read this: U.S. President Barack Obama has rarely used the term, but in his inaugural address on 20 January 2009, he stated "Our nation is at war, against a far-reaching network of violence and hatred." In March 2009 the Defense Department officially changed the name of operations from "Global War on Terror" to "Overseas Contingency Operation" (OCO). In March 2009, the Obama administration requested that Pentagon staff members avoid use of the term, instead using "Overseas Contingency Operation". Basic objectives of the Bush administration "war on terror", such as targeting al Qaeda and building international counterterrorism alliances, remain in place. In December 2012, Jeh Johnson, the General Counsel of the Department of Defense, stated that the military fight will be replaced by a law enforcement operation when speaking at Oxford University, predicting that al Qaeda will be so weakened to be ineffective, and has been "effectively destroyed", and thus the conflict will not be an armed conflict under international law. In May 2013, Obama stated that the goal is "to dismantle specific networks of violent extremists that threaten America"; which coincided with the U.S. Office of Management and Budget having changed the wording from "Overseas Contingency Operations" to "Countering Violent Extremism" in 2010.
Question: What was the "Global War on Terror" officially renamed to in March 2009?

Output: Overseas Contingency Operation
