Problem: Hunter-gatherer:

In the 1950s, Lewis Binford suggested that early humans were obtaining meat via scavenging, not hunting. Early humans in the Lower Paleolithic lived in forests and woodlands, which allowed them to collect seafood, eggs, nuts, and fruits besides scavenging. Rather than killing large animals for meat, according to this view, they used carcasses of such animals that had either been killed by predators or that had died of natural causes. Archaeological and genetic data suggest that the source populations of Paleolithic hunter-gatherers survived in sparsely wooded areas and dispersed through areas of high primary productivity while avoiding dense forest cover.

Where did hunter-gatherer peoples live?
---
A: sparsely wooded areas


Problem: In 1937, IBM's tabulating equipment enabled organizations to process unprecedented amounts of data, its clients including the U.S. Government, during its first effort to maintain the employment records for 26 million people pursuant to the Social Security Act, and the Third Reich, largely through the German subsidiary Dehomag. During the Second World War the company produced small arms for the American war effort (M1 Carbine, and Browning Automatic Rifle). IBM provided translation services for the Nuremberg Trials. In 1947, IBM opened its first office in Bahrain, as well as an office in Saudi Arabia to service the needs of the Arabian-American Oil Company that would grow to become Saudi Business Machines (SBM).
What year did IBM open its first office in Bahrain?

Answer: 1947


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Steven Waldman notes that; "The evangelicals provided the political muscle for the efforts of Madison and Jefferson, not merely because they wanted to block official churches but because they wanted to keep the spiritual and secular worlds apart." "Religious freedom resulted from an alliance of unlikely partners," writes the historian Frank Lambert in his book The Founding Fathers and the Place of Religion in America. "New Light evangelicals such as Isaac Bachus and John Leland joined forces with Deists and skeptics such as James Madison and Thomas Jefferson to fight for a complete separation of church and state."
What profession does Frank Lambert have?
A: historian


Context and question: The Duke and Duchess of York had two children: Elizabeth (called "Lilibet" by the family), and Margaret. The Duke and Duchess and their two daughters lived a relatively sheltered life at their London residence, 145 Piccadilly. They were a close and loving family. One of the few stirs arose when the Canadian Prime Minister, R. B. Bennett, considered the Duke for Governor General of Canada in 1931—a proposal that King George V rejected on the advice of the Secretary of State for Dominion Affairs, J. H. Thomas.
In what year was Margaret born?
Answer: unanswerable


Question: Camouflage is an important defense strategy, which involves the use of coloration or shape to blend into the surrounding environment. This sort of protective coloration is common and widespread among beetle families, especially those that feed on wood or vegetation, such as many of the leaf beetles (family Chrysomelidae) or weevils. In some of these species, sculpturing or various colored scales or hairs cause the beetle to resemble bird dung or other inedible objects. Many of those that live in sandy environments blend in with the coloration of the substrate. Most phasmids are known for effectively replicating the forms of sticks and leaves, and the bodies of some species (such as O. macklotti and Palophus centaurus) are covered in mossy or lichenous outgrowths that supplement their disguise. Some species have the ability to change color as their surroundings shift (B. scabrinota, T. californica). In a further behavioral adaptation to supplement crypsis, a number of species have been noted to perform a rocking motion where the body is swayed from side to side that is thought to reflect the movement of leaves or twigs swaying in the breeze. Another method by which stick insects avoid predation and resemble twigs is by feigning death (catalepsy), where the insect enters a motionless state that can be maintained for a long period. The nocturnal feeding habits of adults also aids Phasmatodea in remaining concealed from predators.
Is there an answer to this question: What is an important defense strategy for insects to survive?

Answer: Camouflage


Problem: Portugal:

On 6 April 2011, after his proposed "Plan for Stability and Growth IV" (PEC IV) was rejected by the Parliament, Prime Minister José Sócrates announced on national television that the country would request financial assistance from the IMF and the European Financial Stability Facility, as Greece and the Republic of Ireland had done previously. It was the third time that the Portuguese government had requested external financial aid from the IMF—the first occasion occurred in the late 1970s following the Carnation's Revolution. In October 2011, Moody's Investor Services downgraded nine Portuguese banks due to financial weakness.

What provoked the first request from Portugal for financial support?
---
A:
Carnation's Revolution
