Context and question: At the 1966 "Man the Hunter" conference, anthropologists Richard Borshay Lee and Irven DeVore suggested that egalitarianism was one of several central characteristics of nomadic hunting and gathering societies because mobility requires minimization of material possessions throughout a population. Therefore, no surplus of resources can be accumulated by any single member. Other characteristics Lee and DeVore proposed were flux in territorial boundaries as well as in demographic composition.
At what conference did Richard Borshay speak?
Answer: Man the Hunter
Context and question: In 2006, IBM launched Secure Blue, encryption hardware that can be built into microprocessors. A year later, IBM unveiled Project Big Green, a re-direction of $1 billion per year across its businesses to increase energy efficiency. On November 2008, IBM's CEO, Sam Palmisano, during a speech at the Council on Foreign Relations, outlined a new agenda for building a Smarter Planet. On March 1, 2011, IBM announced the Smarter Computing framework to support Smarter Planet. On Aug 18, 2011, as part of its effort in cognitive computing, IBM has produced chips that imitate neurons and synapses. These microprocessors do not use von Neumann architecture, and they consume less memory and power.
What is the name of the IBM project that redirected $1 billion each year to increase energy efficiency?
Answer: Project Big Green
Context and question: The onset of symptoms in myocardial infarction (MI) is usually gradual, over several minutes, and rarely instantaneous. Chest pain is the most common symptom of acute MI and is often described as a sensation of tightness, pressure, or squeezing. Chest pain due to ischemia (a lack of blood and hence oxygen supply) of the heart muscle is termed angina pectoris. Pain radiates most often to the left arm, but may also radiate to the lower jaw, neck, right arm, back, and upper abdomen, where it may mimic heartburn. Levine's sign, in which a person localizes the chest pain by clenching their fists over their sternum, has classically been thought to be predictive of cardiac chest pain, although a prospective observational study showed it had a poor positive predictive value.
What is a good way to predict a heart attack?
