Problem: Antibiotics:

Before the early 20th century, treatments for infections were based primarily on medicinal folklore. Mixtures with antimicrobial properties that were used in treatments of infections were described over 2000 years ago. Many ancient cultures, including the ancient Egyptians and ancient Greeks, used specially selected mold and plant materials and extracts to treat infections. More recent observations made in the laboratory of antibiosis between microorganisms led to the discovery of natural antibacterials produced by microorganisms. Louis Pasteur observed, "if we could intervene in the antagonism observed between some bacteria, it would offer perhaps the greatest hopes for therapeutics". The term 'antibiosis', meaning "against life", was introduced by the French bacteriologist Jean Paul Vuillemin as a descriptive name of the phenomenon exhibited by these early antibacterial drugs. Antibiosis was first described in 1877 in bacteria when Louis Pasteur and Robert Koch observed that an airborne bacillus could inhibit the growth of Bacillus anthracis. These drugs were later renamed antibiotics by Selman Waksman, an American microbiologist, in 1942. Synthetic antibiotic chemotherapy as a science and development of antibacterials began in Germany with Paul Ehrlich in the late 1880s. Ehrlich noted certain dyes would color human, animal, or bacterial cells, whereas others did not. He then proposed the idea that it might be possible to create chemicals that would act as a selective drug that would bind to and kill bacteria without harming the human host. After screening hundreds of dyes against various organisms, in 1907, he discovered a medicinally useful drug, the synthetic antibacterial salvarsan now called arsphenamine.

What type of things did American microbiologists use?

Problem: In December 2008, the CTO of Blitz Games announced that it would bring stereoscopic 3D gaming and movie viewing to Xbox 360 and PlayStation 3 with its own technology. This was first demonstrated publicly on PS3 using Sony's own technology in January 2009 at the Consumer Electronics Show. Journalists were shown Wipeout HD and Gran Turismo 5 Prologue in 3D as a demonstration of how the technology might work if it is implemented in the future. Firmware update 3.30 officially allowed PS3 titles to be played in 3D, requiring a compatible display for use. System software update 3.50 prepared it for 3D films. While the game itself must be programmed to take advantage of the 3D technology, titles may be patched to add in the functionality retroactively. Titles with such patches include Wipeout HD, Pain, and Super Stardust HD.
A title with a 3D patch is Super what?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the beginning of 1996, several human rights groups brought cases to hold Shell accountable for alleged human rights violations in Nigeria, including summary execution, crimes against humanity, torture, inhumane treatment and arbitrary arrest and detention. In particular, Shell stood accused of collaborating in the execution of Ken Saro-Wiwa and eight other leaders of the Ogoni tribe of southern Nigeria, who were hanged in 1995 by Nigeria's then military rulers. The lawsuits were brought against Royal Dutch Shell and Brian Anderson, the head of its Nigerian operation. In 2009, Shell agreed to pay $15.5m in a legal settlement. Shell has not accepted any liability over the allegations against it.
When did Shell sue Nigeria?
A: unanswerable

Context and question: Until 1998, the network carried a variety of American programs in addition to its core Canadian programming, directly competing with private Canadian broadcasters such as CTV and Global. Since then, it has restricted itself to Canadian programs, a handful of British programs, and a few American movies and off-network repeats. Since this change, the CBC has sometimes struggled to maintain ratings comparable to those it achieved before 1995, although it has seen somewhat of a ratings resurgence in recent years. In the 2007-08 season, hit series such as Little Mosque on the Prairie and The Border helped the network achieve its strongest ratings performance in over half a decade.
Which recent (2007-2008) shows helped the network regain popularity?
Answer: Little Mosque on the Prairie and The Border

Question: In 2003, the ICZN ruled in its Opinion 2027 that if wild animals and their domesticated derivatives are regarded as one species, then the scientific name of that species is the scientific name of the wild animal. In 2005, the third edition of Mammal Species of the World upheld Opinion 2027 with the name Lupus and the note: "Includes the domestic dog as a subspecies, with the dingo provisionally separate - artificial variants created by domestication and selective breeding". However, Canis familiaris is sometimes used due to an ongoing nomenclature debate because wild and domestic animals are separately recognizable entities and that the ICZN allowed users a choice as to which name they could use, and a number of internationally recognized researchers prefer to use Canis familiaris.
Is there an answer to this question: Many researchers prefer what term?

Answer: Canis familiaris.

Question: With the collapse of Roman rule in the early 5th century, London ceased to be a capital and the walled city of Londinium was effectively abandoned, although Roman civilisation continued in the St Martin-in-the-Fields area until around 450. From around 500, an Anglo-Saxon settlement known as Lundenwic developed in the same area, slightly to the west of the old Roman city. By about 680, it had revived sufficiently to become a major port, although there is little evidence of large-scale production of goods. From the 820s the town declined because of repeated Viking invasions. There are three recorded Viking assaults on London; two of which were successful in 851 and 886 AD, although they were defeated during the attack of 994 AD.
Is there an answer to this question: What area continued to exist after Londinium was abandoned following the end of Roman rule?

Answer:
St Martin-in-the-Fields
