Problem: Nutrition:

Research in the field of nutrition has greatly contributed in finding out the essential facts about how environmental depletion can lead to crucial nutrition-related health problems like contamination, spread of contagious diseases, malnutrition, etc. Moreover, environmental contamination due to discharge of agricultural as well as industrial chemicals like organocholrines, heavy metal, and radionucleotides may adversely affect the human and the ecosystem as a whole. As far as safety of the human health is concerned, then these environmental contaminants can reduce people's nutritional status and health. This could directly or indirectly cause drastic changes in their diet habits. Hence, food-based remedial as well as preventive strategies are essential to address global issues like hunger and malnutrition and to enable the susceptible people to adapt themselves to all these environmental as well as socio-economic alterations.

A: crucial nutrition-related health problems

Problem: In 1882, Albert Zahm (John Zahm's brother) built an early wind tunnel used to compare lift to drag of aeronautical models. Around 1899, Professor Jerome Green became the first American to send a wireless message. In 1931, Father Julius Nieuwland performed early work on basic reactions that was used to create neoprene. Study of nuclear physics at the university began with the building of a nuclear accelerator in 1936, and continues now partly through a partnership in the Joint Institute for Nuclear Astrophysics.
What did the brother of John Zahm construct at Notre Dame?

Answer: an early wind tunnel

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The main treatment for MI with ECG evidence of ST elevation (STEMI) include thrombolysis and percutaneous coronary intervention. Primary percutaneous coronary intervention (PCI) is the treatment of choice for STEMI if it can be performed in a timely manner. If PCI cannot be performed within 90 to 120 minutes then thrombolysis, preferably within 30 minutes of arrival to hospital, is recommended. If a person has had symptoms for 12 to 24 hours evidence for thrombolysis is less and if they have had symptoms for more than 24 hours it is not recommended.
PCI and what treatment must be performed within 90 to 120 minutes?
A: unanswerable

Context and question: Some of the most influential theorists on emotion from the 20th century have died in the last decade. They include Magda B. Arnold (19032002), an American psychologist who developed the appraisal theory of emotions; Richard Lazarus (19222002), an American psychologist who specialized in emotion and stress, especially in relation to cognition; Herbert A. Simon (19162001), who included emotions into decision making and artificial intelligence; Robert Plutchik (19282006), an American psychologist who developed a psychoevolutionary theory of emotion; Robert Zajonc (19232008) a PolishAmerican social psychologist who specialized in social and cognitive processes such as social facilitation; Robert C. Solomon (19422007), an American philosopher who contributed to the theories on the philosophy of emotions with books such as What Is An Emotion?: Classic and Contemporary Readings (Oxford, 2003); Peter Goldie (19462011), a British philosopher who specialized in ethics, aesthetics, emotion, mood and character; Nico Frijda (19272015), a Dutch psychologist who advanced the theory that human emotions serve to promote a tendency to undertake actions that are appropriate in the circumstances, detailed in his book The Emotions (1986).
When did Richard Lazarus work?
Answer: unanswerable

Question: In January 1871, George Jackson Mivart's On the Genesis of Species listed detailed arguments against natural selection, and claimed it included false metaphysics. Darwin made extensive revisions to the sixth edition of the Origin (this was the first edition in which he used the word "evolution" which had commonly been associated with embryological development, though all editions concluded with the word "evolved"), and added a new chapter VII, Miscellaneous objections, to address Mivart's arguments.
Is there an answer to this question: When did Charles Darwin first use the word "evolution" in On the Origin of Species?

Answer: the sixth edition

In 1870, following the stunning defeat of the French Army by the Germans in the Franco-Prussian War, French workers and socialist revolutionaries seized Paris and created the Paris Commune. The Commune lasted for two months before it was crushed by the French Army, with much bloodshed. The original red banners of the Commune became icons of the socialist revolution; in 1921 members of the French Communist Party came to Moscow and presented the new Soviet government with one of the original Commune banners; it was placed (and is still in place) in the tomb of Vladimir Lenin, next to his open coffin.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): For how long did the Paris Commune exist?
Ah, so..
two months
