Problem: Pharmaceutical industry:

Patents have been criticized in the developing world, as they are thought to reduce access to existing medicines. Reconciling patents and universal access to medicine would require an efficient international policy of price discrimination. Moreover, under the TRIPS agreement of the World Trade Organization, countries must allow pharmaceutical products to be patented. In 2001, the WTO adopted the Doha Declaration, which indicates that the TRIPS agreement should be read with the goals of public health in mind, and allows some methods for circumventing pharmaceutical monopolies: via compulsory licensing or parallel imports, even before patent expiration.

The Doha Declaration allows for what ways for monopolies to be bypassed?

A: compulsory licensing or parallel imports

Problem: Law enforcement in Ancient China was carried out by "prefects" for thousands of years since it developed in both the Chu and Jin kingdoms of the Spring and Autumn period. In Jin, dozens of prefects were spread across the state, each having limited authority and employment period. They were appointed by local magistrates, who reported to higher authorities such as governors, who in turn were appointed by the emperor, and they oversaw the civil administration of their "prefecture", or jurisdiction. Under each prefect were "subprefects" who helped collectively with law enforcement in the area. Some prefects were responsible for handling investigations, much like modern police detectives. Prefects could also be women. The concept of the "prefecture system" spread to other cultures such as Korea and Japan.
What did ancient China call its police?

John XXIII died of peritonitis caused by a perforated stomach at 19:49 local time on 3 June 1963 at the age of 81, ending a historic pontificate of four years and seven months. He died just as a Mass for him finished in Saint Peter's Square below, celebrated by Luigi Traglia. After he died, his brow was ritually tapped to see if he was dead, and those with him in the room said prayers. Then the room was illuminated, thus informing the people of what had happened. He was buried on 6 June in the Vatican grottos. Two wreaths, placed on the two sides of his tomb, were donated by the prisoners of the Regina Coeli prison and the Mantova jail in Verona. On 22 June 1963, one day after his friend and successor Pope Paul VI was elected, the latter prayed at his tomb.
Where was Luigi Traglia buried?
A: unanswerable

Context and question: The pits and lands themselves do not directly represent the zeros and ones of binary data. Instead, non-return-to-zero, inverted encoding is used: a change from pit to land or land to pit indicates a one, while no change indicates a series of zeros. There must be at least two and no more than ten zeros between each one, which is defined by the length of the pit. This in turn is decoded by reversing the eight-to-fourteen modulation used in mastering the disc, and then reversing the cross-interleaved ReedSolomon coding, finally revealing the raw data stored on the disc. These encoding techniques (defined in the Red Book) were originally designed for CD Digital Audio, but they later became a standard for almost all CD formats (such as CD-ROM).
Who designed the CD Digital Audio coding techniques?
Answer: unanswerable

Question: The colloquialism "buck"(s) (much like the British word "quid"(s, pl) for the pound sterling) is often used to refer to dollars of various nations, including the U.S. dollar. This term, dating to the 18th century, may have originated with the colonial leather trade. It may also have originated from a poker term. "Greenback" is another nickname originally applied specifically to the 19th century Demand Note dollars created by Abraham Lincoln to finance the costs of the Civil War for the North. The original note was printed in black and green on the back side. It is still used to refer to the U.S. dollar (but not to the dollars of other countries). Other well-known names of the dollar as a whole in denominations include "greenmail", "green" and "dead presidents" (the last because deceased presidents are pictured on most bills).
Is there an answer to this question: What was the nickname given to the Demand Note dollars that were used to finance the Civil War?

Answer: Greenback

Allusions to legal issues in To Kill a Mockingbird, particularly in scenes outside of the courtroom, has drawn the attention from legal scholars. Claudia Durst Johnson writes that "a greater volume of critical readings has been amassed by two legal scholars in law journals than by all the literary scholars in literary journals". The opening quote by the 19th-century essayist Charles Lamb reads: "Lawyers, I suppose, were children once." Johnson notes that even in Scout and Jem's childhood world, compromises and treaties are struck with each other by spitting on one's palm and laws are discussed by Atticus and his children: is it right that Bob Ewell hunts and traps out of season? Many social codes are broken by people in symbolic courtrooms: Mr. Dolphus Raymond has been exiled by society for taking a black woman as his common-law wife and having interracial children; Mayella Ewell is beaten by her father in punishment for kissing Tom Robinson; by being turned into a non-person, Boo Radley receives a punishment far greater than any court could have given him. Scout repeatedly breaks codes and laws and reacts to her punishment for them. For example, she refuses to wear frilly clothes, saying that Aunt Alexandra's "fanatical" attempts to place her in them made her feel "a pink cotton penitentiary closing in on [her]". Johnson states, "[t]he novel is a study of how Jem and Scout begin to perceive the complexity of social codes and how the configuration of relationships dictated by or set off by those codes fails or nurtures the inhabitants of (their) small worlds."
What is another name for Scout's pink cotton penitentiary?
A:
frilly clothes
