Input: Read this: In addition to strictness in character size and shape, Chinese characters are written with very precise rules. The most important rules regard the strokes employed, stroke placement, and stroke order. Just as each region that uses Chinese characters has standardized character forms, each also has standardized stroke orders, with each standard being different. Most characters can be written with just one correct stroke order, though some words also have many valid stroke orders, which may occasionally result in different stroke counts. Some characters are also written with different stroke orders due to character simplification.
Question: What are written with very precise rules?

Output: Chinese characters


QUES: John was deeply suspicious of the barons, particularly those with sufficient power and wealth to potentially challenge the king. Numerous barons were subjected to John's malevolentia, even including William Marshal, a famous knight and baron normally held up as a model of utter loyalty. The most infamous case, which went beyond anything considered acceptable at the time, proved to be that of William de Braose, a powerful marcher lord with lands in Ireland. De Braose was subjected to punitive demands for money, and when he refused to pay a huge sum of 40,000 marks (equivalent to £26,666 at the time),[nb 13] his wife and one of his sons were imprisoned by John, which resulted in their deaths. De Braose died in exile in 1211, and his grandsons remained in prison until 1218. John's suspicions and jealousies meant that he rarely enjoyed good relationships with even the leading loyalist barons.

John was deeply suspicious of who?
What is the answer?
ANS: the barons


QUES: TB infection begins when the mycobacteria reach the pulmonary alveoli, where they invade and replicate within endosomes of alveolar macrophages. Macrophages identify the bacterium as foreign and attempt to eliminate it by phagocytosis. During this process, the bacterium is enveloped by the macrophage and stored temporarily in a membrane-bound vesicle called a phagosome. The phagosome then combines with a lysosome to create a phagolysosome. In the phagolysosome, the cell attempts to use reactive oxygen species and acid to kill the bacterium. However, M. tuberculosis has a thick, waxy mycolic acid capsule that protects it from these toxic substances. M. tuberculosis is able to reproduce inside the macrophage and will eventually kill the immune cell.
What envelopes the macrophage?

ANS: unanswerable


UNFPA has been falsely accused by anti-family planning groups of providing support for government programs which have promoted forced-abortions and coercive sterilizations. Controversies regarding these claims have resulted in a sometimes shaky relationship between the organization and three presidential administrations, that of Ronald Reagan, George H. W. Bush and George W. Bush, withholding funding from the UNFPA.  
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was UNFPA accurately accused by?
Ah, so.. unanswerable


Question: In 2012, news was released about a new farming site discovered in Munam-ri, Goseong, Gangwon Province, South Korea, which may be the earliest farmland known to date in east Asia. "No remains of an agricultural field from the Neolithic period have been found in any East Asian country before, the institute said, adding that the discovery reveals that the history of agricultural cultivation at least began during the period on the Korean Peninsula". The farm was dated between 3600 and 3000 B.C. Pottery, stone projectile points, and possible houses were also found. "In 2002, researchers discovered prehistoric earthenware, jade earrings, among other items in the area". The research team will perform accelerator mass spectrometry (AMS) dating to retrieve a more precise date for the site.
Try to answer this question if possible: What time period was the AMS farm site dated?
Answer: unanswerable


Problem: Auto racing is also popular in the area. The Richmond International Raceway (RIR) has hosted NASCAR Sprint Cup races since 1953, as well as the Capital City 400 from 1962 − 1980. RIR also hosted IndyCar's Suntrust Indy Challenge from 2001 − 2009. Another track, Southside Speedway, has operated since 1959 and sits just southwest of Richmond in Chesterfield County. This .333-mile (0.536 km) oval short-track has become known as the "Toughest Track in the South" and "The Action Track", and features weekly stock car racing on Friday nights. Southside Speedway has acted as the breeding grounds for many past NASCAR legends including Richard Petty, Bobby Allison and Darrell Waltrip, and claims to be the home track of NASCAR superstar Denny Hamlin.
What is the shape of Southside Speedway?
