Problem: Please answer a question about the following article about Mosaic:
The great Navicella mosaic (13051313) in the atrium of the Old St. Peter's is attributed to Giotto di Bondone. The giant mosaic, commissioned by Cardinal Jacopo Stefaneschi, was originally situated on the eastern porch of the old basilica and occupied the whole wall above the entrance arcade facing the courtyard. It depicted St. Peter walking on the waters. This extraordinary work was mainly destroyed during the construction of the new St. Peter's in the 17th century. Navicella means "little ship" referring to the large boat which dominated the scene, and whose sail, filled by the storm, loomed over the horizon. Such a natural representation of a seascape was known only from ancient works of art.
Who commissioned the Navicella mosaic?
A: Cardinal Jacopo Stefaneschi
Problem: Please answer a question about the following article about Spectre (2015 film):
Despite being an original story, Spectre draws on Ian Fleming's source material, most notably in the character of Franz Oberhauser, played by Christoph Waltz. Oberhauser shares his name with Hannes Oberhauser, a background character in the short story "Octopussy" from the Octopussy and The Living Daylights collection, and who is named in the film as having been a temporary legal guardian of a young Bond in 1983. Similarly, Charmian Bond is shown to have been his full-time guardian, observing the back story established by Fleming. With the acquisition of the rights to Spectre and its associated characters, screenwriters Neal Purvis and Robert Wade revealed that the film would provide a minor retcon to the continuity of the previous films, with the Quantum organisation alluded to in Casino Royale and introduced in Quantum of Solace reimagined as a division within Spectre rather than an independent organisation.
What actor portrayed Franz Oberhauser?
A: Christoph Waltz.
Problem: Please answer a question about the following article about Antenna (radio):
Antennas are required by any radio receiver or transmitter to couple its electrical connection to the electromagnetic field. Radio waves are electromagnetic waves which carry signals through the air (or through space) at the speed of light with almost no transmission loss. Radio transmitters and receivers are used to convey signals (information) in systems including broadcast (audio) radio, television, mobile telephones, Wi-Fi (WLAN) data networks, trunk lines and point-to-point communications links (telephone, data networks), satellite links, many remote controlled devices such as garage door openers, and wireless remote sensors, among many others. Radio waves are also used directly for measurements in technologies including radar, GPS, and radio astronomy. In each and every case, the transmitters and receivers involved require antennas, although these are sometimes hidden (such as the antenna inside an AM radio or inside a laptop computer equipped with Wi-Fi).
What is essential for the mating of the elements that create radio waves?
A: Antennas
Problem: Please answer a question about the following article about John Kerry:
On March 13, 1969, on the Bai Hap River, Kerry was in charge of one of five Swift boats that were returning to their base after performing an Operation Sealords mission to transport South Vietnamese troops from the garrison at Cai Nuoc and MIKE Force advisors for a raid on a Vietcong camp located on the Rach Dong Cung canal. Earlier in the day, Kerry received a slight shrapnel wound in the buttocks from blowing up a rice bunker. Debarking some but not all of the passengers at a small village, the boats approached a fishing weir; one group of boats went around to the left of the weir, hugging the shore, and a group with Kerry's PCF-94 boat went around to the right, along the shoreline. A mine was detonated directly beneath the lead boat, PCF-3, as it crossed the weir to the left, lifting PCF-3 "about 2-3 ft out of water".
What was Kerry doing when he was wounded on Mar 13, 1969?
A:
blowing up a rice bunker
