Problem: Kerry received his second Purple Heart for a wound received in action on the Bo e River on February 20, 1969. The plan had been for the Swift boats to be accompanied by support helicopters. On the way up the Bo De, however, the helicopters were attacked. As the Swift boats reached the Cua Lon River, Kerry's boat was hit by a B-40 rocket (rocket propelled grenade round), and a piece of shrapnel hit Kerry's left leg, wounding him. Thereafter, enemy fire ceased and his boat reached the Gulf of Thailand safely. Kerry continues to have shrapnel embedded in his left thigh because the doctors that first treated him decided to remove the damaged tissue and close the wound with sutures rather than make a wide opening to remove the shrapnel. Though wounded like several others earlier that day, Kerry did not lose any time off from duty.
What munition hit Kerry's boat?
The answer is the following: a B-40 rocket

Problem: From 1879, Watch Tower supporters gathered as autonomous congregations to study the Bible topically. Thirty congregations were founded, and during 1879 and 1880, Russell visited each to provide the format he recommended for conducting meetings. As congregations continued to form during Russell's ministry, they each remained self-administrative, functioning under the congregationalist style of church governance. In 1881, Zion's Watch Tower Tract Society was presided over by William Henry Conley, and in 1884, Charles Taze Russell incorporated the society as a non-profit business to distribute tracts and Bibles. By about 1900, Russell had organized thousands of part- and full-time colporteurs, and was appointing foreign missionaries and establishing branch offices. By the 1910s, Russell's organization maintained nearly a hundred "pilgrims," or traveling preachers. Russell engaged in significant global publishing efforts during his ministry, and by 1912, he was the most distributed Christian author in the United States.
What did the congregations which continued to form during Russell's ministry remain?
The answer is the following: self-administrative

Problem: 23-year-old Candice Glover won the season with Kree Harrison taking the runner-up spot. Glover is the first female to win American Idol since Jordin Sparks. Glover released "I Am Beautiful" as a single while Harrison released "All Cried Out" immediately after the show. Glover sold poorly with her debut album, and this is also the first season that the runner-up was not signed by a music label.
Which contestant came in second on season 12 of American Idol?
The answer is the following: Kree Harrison

Problem: While the use of iron started to become more widespread around 1200 BC, mainly because of interruptions in the trade routes for tin, the metal is much softer than bronze. However, very small amounts of steel, (an alloy of iron and around 1% carbon), was always a byproduct of the bloomery process. The ability to modify the hardness of steel by heat treatment had been known since 1100 BC, and the rare material was valued for the manufacture of tools and weapons. Because the ancients could not produce temperatures high enough to melt iron fully, the production of steel in decent quantities did not occur until the introduction of blister steel during the Middle Ages. This method introduced carbon by heating wrought iron in charcoal for long periods of time, but the penetration of carbon was not very deep, so the alloy was not homogeneous. In 1740, Benjamin Huntsman began melting blister steel in a crucible to even out the carbon content, creating the first process for the mass production of tool steel. Huntsman's process was used for manufacturing tool steel until the early 1900s.
Who created the first process for the mass production of tool steel?
The answer is the following:
Benjamin Huntsman
