Problem: Antibiotics:

Vaccines rely on immune modulation or augmentation. Vaccination either excites or reinforces the immune competence of a host to ward off infection, leading to the activation of macrophages, the production of antibodies, inflammation, and other classic immune reactions. Antibacterial vaccines have been responsible for a drastic reduction in global bacterial diseases. Vaccines made from attenuated whole cells or lysates have been replaced largely by less reactogenic, cell-free vaccines consisting of purified components, including capsular polysaccharides and their conjugates, to protein carriers, as well as inactivated toxins (toxoids) and proteins.

What types of vaccines have been phased out?
---
A: Vaccines made from attenuated whole cells or lysates

Problem: Meanwhile, Kerry's staff began their own investigations and, on October 14, issued a report that exposed illegal activities on the part of Lieutenant Colonel Oliver North, who had set up a private network involving the National Security Council and the CIA to deliver military equipment to right-wing Nicaraguan rebels (Contras). In effect, North and certain members of the President's administration were accused by Kerry's report of illegally funding and supplying armed militants without the authorization of Congress. Kerry's staff investigation, based on a year-long inquiry and interviews with fifty unnamed sources, is said to raise "serious questions about whether the United States has abided by the law in its handling of the contras over the past three years."
What government agencies worked with North?

Answer: the National Security Council and the CIA

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. Douglas Mawson, who assumed the leadership of the Magnetic Pole party on their perilous return, went on to lead several expeditions until retiring in 1931. In addition, Shackleton himself and three other members of his expedition made several firsts in December 1908 February 1909: they were the first humans to traverse the Ross Ice Shelf, the first to traverse the Transantarctic Mountains (via the Beardmore Glacier), and the first to set foot on the South Polar Plateau. An expedition led by Norwegian polar explorer Roald Amundsen from the ship Fram became the first to reach the geographic South Pole on 14 December 1911, using a route from the Bay of Whales and up the Axel Heiberg Glacier. One month later, the doomed Scott Expedition reached the pole.
When did Mawson retire after leading several expeditions?
A: 1931

Context and question: While worship in the Temple in Jerusalem included musical instruments (2 Chronicles 29:2527), traditional Jewish religious services in the Synagogue, both before and after the last destruction of the Temple, did not include musical instruments given the practice of scriptural cantillation. The use of musical instruments is traditionally forbidden on the Sabbath out of concern that players would be tempted to repair (or tune) their instruments, which is forbidden on those days. (This prohibition has been relaxed in many Reform and some Conservative congregations.) Similarly, when Jewish families and larger groups sing traditional Sabbath songs known as zemirot outside the context of formal religious services, they usually do so a cappella, and Bar and Bat Mitzvah celebrations on the Sabbath sometimes feature entertainment by a cappella ensembles. During the Three Weeks musical instruments are prohibited. Many Jews consider a portion of the 49-day period of the counting of the omer between Passover and Shavuot to be a time of semi-mourning and instrumental music is not allowed during that time. This has led to a tradition of a cappella singing sometimes known as sefirah music.
What Temple forbade the use of instruments?
Answer: unanswerable

Question: In 2003, Nintendo announced that a new The Legend of Zelda game was in the works for the GameCube by the same team that had created the cel-shaded The Wind Waker. At the following year's Game Developers Conference, director Eiji Aonuma unintentionally revealed that the game's sequel was in development under the working title The Wind Waker 2; it was set to use a similar graphical style to that of its predecessor. Nintendo of America told Aonuma that North American sales of The Wind Waker were sluggish because its cartoon appearance created the impression that the game was designed for a young audience. Concerned that the sequel would have the same problem, Aonuma expressed to producer Shigeru Miyamoto that he wanted to create a realistic Zelda game that would appeal to the North American market. Miyamoto, hesitant about solely changing the game's presentation, suggested the team's focus should instead be on coming up with gameplay innovations. He advised that Aonuma should start by doing what could not be done in Ocarina of Time, particularly horseback combat.[l]
Is there an answer to this question: Who was the director that unintentionally announced a Zelda game was in the works?

Answer: Eiji Aonuma

Problem: Mosaic:

Mosaic art also flourished in Christian Petra where three Byzantine churches were discovered. The most important one was uncovered in 1990. It is known that the walls were also covered with golden glass mosaics but only the floor panels survived as usual. The mosaic of the seasons in the southern aisle is from this first building period from the middle of the 5th century. In the first half of the 6th century the mosaics of the northern aisle and the eastern end of the southern aisle were installed. They depict native as well as exotic or mythological animals, and personifications of the Seasons, Ocean, Earth and Wisdom.

What century was the oldest known mosaic at the church discovered in 1990?
---
A:
the 5th
