Question: During his tour on the guided missile frigate USS Gridley, Kerry requested duty in South Vietnam, listing as his first preference a position as the commander of a Fast Patrol Craft (PCF), also known as a "Swift boat." These 50-foot (15 m) boats have aluminum hulls and have little or no armor, but are heavily armed and rely on speed. "I didn't really want to get involved in the war", Kerry said in a book of Vietnam reminiscences published in 1986. "When I signed up for the swift boats, they had very little to do with the war. They were engaged in coastal patrolling and that's what I thought I was going to be doing." However, his second choice of billet was on a river patrol boat, or "PBR", which at the time was serving a more dangerous duty on the rivers of Vietnam.
Is there an answer to this question: What was the formal name of 'swift boats'?

Answer: Fast Patrol Craft

Question: Elementary and secondary public schools are overseen by the North Carolina Department of Public Instruction. The North Carolina Superintendent of Public Instruction is the secretary of the North Carolina State Board of Education, but the board, rather than the superintendent, holds most of the legal authority for making public education policy. In 2009, the board's chairman also became the "chief executive officer" for the state's school system. North Carolina has 115 public school systems, each of which is overseen by a local school board. A county may have one or more systems within it. The largest school systems in North Carolina are the Wake County Public School System, Charlotte-Mecklenburg Schools, Guilford County Schools, Winston-Salem/Forsyth County Schools, and Cumberland County Schools. In total there are 2,425 public schools in the state, including 99 charter schools. North Carolina Schools were segregated until the Brown v. Board of Education trial and the release of the Pearsall Plan.
Is there an answer to this question: What year did the boards chairman become the Chief Executive officer of public schools?

Answer:
2009
