Question: San Diego is one of the top-ten best climates in the Farmers' Almanac and is one of the two best summer climates in America as scored by The Weather Channel. Under the KoppenGeiger climate classification system, the San Diego area has been variously categorized as having either a semi-arid climate (BSh in the original classification and BSkn in modified Koppen classification) or a Mediterranean climate (Csa and Csb). San Diego's climate is characterized by warm, dry summers and mild winters with most of the annual precipitation falling between December and March. The city has a mild climate year-round, with an average of 201 days above 70 F (21 C) and low rainfall (913 inches [230330 mm] annually). Dewpoints in the summer months range from 57.0 F (13.9 C) to 62.4 F (16.9 C).

Question: In May and June 1835, the area which is now central and northern Melbourne was explored by John Batman, a leading member of the Port Phillip Association in Van Diemen's Land (now known as Tasmania), who claimed to have negotiated a purchase of 600,000 acres (2,400 km2) with eight Wurundjeri elders. Batman selected a site on the northern bank of the Yarra River, declaring that "this will be the place for a village". Batman then returned to Launceston in Tasmania. In early August 1835 a different group of settlers, including John Pascoe Fawkner, left Launceston on the ship Enterprize. Fawkner was forced to disembark at Georgetown, Tasmania, because of outstanding debts. The remainder of the party continued and arrived at the mouth of the Yarra River on 15 August 1835. On 30 August 1835 the party disembarked and established a settlement at the site of the current Melbourne Immigration Museum. Batman and his group arrived on 2 September 1835 and the two groups ultimately agreed to share the settlement.
Is there an answer to this question: How many elders did John Batman claim to have negotiated with?

Question: When the board has no embedded components it is more correctly called a printed wiring board (PWB) or etched wiring board. However, the term printed wiring board has fallen into disuse.

Question: On Saturday, 24 June 1950, U.S. Secretary of State Dean Acheson informed President Truman that the North Koreans had invaded South Korea. Truman and Acheson discussed a U.S. invasion response and agreed that the United States was obligated to act, paralleling the North Korean invasion with Adolf Hitler's aggressions in the 1930s, with the conclusion being that the mistake of appeasement must not be repeated. Several U.S. industries were mobilized to supply materials, labor, capital, production facilities, and other services necessary to support the military objectives of the Korean War. However, President Truman later acknowledged that he believed fighting the invasion was essential to the American goal of the global containment of communism as outlined in the National Security Council Report 68 (NSC-68) (declassified in 1975):
