Problem: Pain:

The International Association for the Study of Pain advocates that the relief of pain should be recognized as a human right, that chronic pain should be considered a disease in its own right, and that pain medicine should have the full status of a specialty. It is a specialty only in China and Australia at this time. Elsewhere, pain medicine is a subspecialty under disciplines such as anesthesiology, physiatry, neurology, palliative medicine and psychiatry. In 2011, Human Rights Watch alerted that tens of millions of people worldwide are still denied access to inexpensive medications for severe pain.

As of 2011, how many people worldwide are still denied access to inexpensive medications for severe pain?
---
A: tens of millions


Problem: Infants do not have the language ability to report on their memories and so verbal reports cannot be used to assess very young children’s memory. Throughout the years, however, researchers have adapted and developed a number of measures for assessing both infants’ recognition memory and their recall memory. Habituation and operant conditioning techniques have been used to assess infants’ recognition memory and the deferred and elicited imitation techniques have been used to assess infants’ recall memory.
Why can verbal report be used to assess very young children's memory?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The consensus among linguists is that modern, standard Czech originated during the eighteenth century. By then the language had developed a literary tradition, and since then it has changed little; journals from that period have no substantial differences from modern standard Czech, and contemporary Czechs can understand them with little difficulty. Changes include the morphological shift of í to ej and é to í (although é survives for some uses) and the merging of í and the former ejí. Sometime before the eighteenth century, the Czech language abandoned a distinction between phonemic /l/ and /ʎ/ which survives in Slovak.
What kind of differences do writings from the past have from modern Slovak?
A: unanswerable


Context and question: But in statistical mechanics things get more complicated. On one hand, statistical mechanics is far superior to classical thermodynamics, in that thermodynamic behavior, such as glass breaking, can be explained by the fundamental laws of physics paired with a statistical postulate. But statistical mechanics, unlike classical thermodynamics, is time-reversal symmetric. The second law of thermodynamics, as it arises in statistical mechanics, merely states that it is overwhelmingly likely that net entropy will increase, but it is not an absolute law.
What type of mechanics help to simplify things?
Answer: unanswerable


Question: It is classified as a Beta World City, ranking seventh in Latin America and 73rd in the world. Described as a "vibrant, eclectic place with a rich cultural life", and "a thriving tech center and entrepreneurial culture", Montevideo ranks 8th in Latin America on the 2013 MasterCard Global Destination Cities Index. By 2014, is also regarded as the fifth most gay-friendly major city in the world, first in Latin America. It is the hub of commerce and higher education in Uruguay as well as its chief port. The city is also the financial and cultural hub of a larger metropolitan area, with a population of around 2 million.
Is there an answer to this question: Montevideo is the chief port of what area?

Answer: Uruguay


Question: He attained a perfect score on the graduate school entrance exams to Princeton University in mathematics and physics—an unprecedented feat—but did rather poorly on the history and English portions. Attendees at Feynman's first seminar included Albert Einstein, Wolfgang Pauli, and John von Neumann. He received a PhD from Princeton in 1942; his thesis advisor was John Archibald Wheeler. Feynman's thesis applied the principle of stationary action to problems of quantum mechanics, inspired by a desire to quantize the Wheeler–Feynman absorber theory of electrodynamics, laying the groundwork for the "path integral" approach and Feynman diagrams, and was titled "The Principle of Least Action in Quantum Mechanics".
Is there an answer to this question: What score did Feyman receive on his math and physics entrance exams?

Answer:
perfect score
