Input: Read this: There are a number of proposals to redefine certain of the SI base units in terms of fundamental physical constants. This has already been done for the metre, which is defined in terms of a fixed value of the speed of light. The most urgent unit on the list for redefinition is the kilogram, whose value has been fixed for all science (since 1889) by the mass of a small cylinder of platinum–iridium alloy kept in a vault just outside Paris. While nobody knows if the mass of the International Prototype Kilogram has changed since 1889 – the value 1 kg of its mass expressed in kilograms is by definition unchanged and therein lies one of the problems – it is known that over such a timescale the many similar Pt–Ir alloy cylinders kept in national laboratories around the world, have changed their relative mass by several tens of parts per million, however carefully they are stored, and the more so the more they have been taken out and used as mass standards. A change of several tens of micrograms in one kilogram is equivalent to the current uncertainty in the value of the Planck constant in SI units.
Question: What value has consistently changed since 1889?

Output: unanswerable


QUES: The legend of Virgil in his Basket arose in the Middle Ages, and is often seen in art and mentioned in literature as part of the Power of Women literary topos, demonstrating the disruptive force of female attractiveness on men. In this story Virgil became enamoured of a beautiful woman, sometimes described as the emperor's daughter or mistress and called Lucretia. She played him along and agreed to an assignation at her house, which he was to sneak into at night by climbing into a large basket let down from a window. When he did so he was only hoisted halfway up the wall and then left him trapped there into the next day, exposed to public ridicule. The story paralleled that of Phyllis riding Aristotle. Among other artists depicting the scene, Lucas van Leyden made a woodcut and later an engraving.

Who was one of the writers who wrote about Virgil in his Basket?

QUES: Several organizations concerned with antimicrobial resistance are lobbying to eliminate the unnecessary use of antibiotics. The issues of misuse and overuse of antibiotics have been addressed by the formation of the US Interagency Task Force on Antimicrobial Resistance. This task force aims to actively address antimicrobial resistance, and is coordinated by the US Centers for Disease Control and Prevention, the Food and Drug Administration (FDA), and the National Institutes of Health (NIH), as well as other US agencies. An NGO campaign group is Keep Antibiotics Working. In France, an "Antibiotics are not automatic" government campaign started in 2002 and led to a marked reduction of unnecessary antibiotic prescriptions, especially in children.
What is the name of a US government agency tasked with trying to stop the FDA?

As Universal's main product had always been low-budget film, it was one of the last major studios to have a contract with Technicolor. The studio did not make use of the three-strip Technicolor process until Arabian Nights (1942), starring Jon Hall and Maria Montez. The following year, Technicolor was also used in Universal's remake of their 1925 horror melodrama, Phantom of the Opera with Claude Rains and Nelson Eddy. With the success of their first two pictures, a regular schedule of high-budget, Technicolor films followed.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was Universal's first version of the Phantom of the Opera made?
Ah, so.. 1925


Question: Enisa Kafadar argues that there is only one Serbo-Croatian language with several varieties. This has made possible to include all four varieties into a new grammar book. Daniel Bunčić concludes that it is a pluricentric language, with four standard variants spoken in Serbia, Croatia, Montenegro and Bosnia and Herzegovina. The mutual intelligibility between their speakers "exceeds that between the standard variants of English, French, German, or Spanish". Other linguists have argued that the differences between the variants of Serbo-Croatian are less significant than those between the variants of English, German,, Dutch, and Hindi-Urdu.
Try to answer this question if possible: How many varieties does Enisa Kafadar aruge there are in Hindi-Urdu?
Answer: unanswerable


Problem: In 1994, over a hundred intrusions were made by unidentified crackers into the Rome Laboratory, the US Air Force's main command and research facility. Using trojan horses, hackers were able to obtain unrestricted access to Rome's networking systems and remove traces of their activities. The intruders were able to obtain classified files, such as air tasking order systems data and furthermore able to penetrate connected networks of National Aeronautics and Space Administration's Goddard Space Flight Center, Wright-Patterson Air Force Base, some Defense contractors, and other private sector organizations, by posing as a trusted Rome center user.
How were hackers able to penetrate connected networks?
---
Answer:
by posing as a trusted Rome center user
