Problem: Hunter-gatherer:

Many groups continued their hunter-gatherer ways of life, although their numbers have continually declined, partly as a result of pressure from growing agricultural and pastoral communities. Many of them reside in the developing world, either in arid regions or tropical forests. Areas that were formerly available to hunter-gatherers wereand continue to beencroached upon by the settlements of agriculturalists. In the resulting competition for land use, hunter-gatherer societies either adopted these practices or moved to other areas. In addition, Jared Diamond has blamed a decline in the availability of wild foods, particularly animal resources. In North and South America, for example, most large mammal species had gone extinct by the end of the Pleistoceneaccording to Diamond, because of overexploitation by humans, although the overkill hypothesis he advocates is strongly contested.[by whom?]

All large mammal species have gone extinct in what countries?

Problem: Governments have seen alternates between Bharatiya Janata Party (BJP) and Indian National Congress (INC), no third front ever has become significant. In 2003, the state legislative assembly was won by the Indian National Congress and Virbhadra Singh was elected as the chief minister of the state. In the assembly elections held in December 2007, the BJP secured a landslide victory. The BJP won 41 of the 68 seats while the Congress won only 23 of the 68 seats. BJP's Prem Kumar Dhumal was sworn in as Chief Minister of Himachal Pradesh on 30 December 2007.
When did the Indian National Congress win by a landslide?

President Abraham Lincoln visited General Grant at Petersburg on April 3, and took a launch to Richmond the next day, while Jefferson Davis attempted to organize his Confederate government at Danville. Lincoln met Confederate assistant secretary of War John A. Campbell, and handed him a note inviting Virginia's legislature to end their rebellion. After Campbell spun the note to Confederate legislators as a possible end to the Emancipation Proclamation, Lincoln rescinded his offer and ordered General Weitzel to prevent the Confederate state legislature from meeting. Union forces killed, wounded or captured 8000 Confederate troops at Saylor's Creek southwest of Petersburg on April 6. General Lee continued to reject General Grant's surrender suggestion until Sheridan's infantry and cavalry appeared in front of his retreating army on April 8. He surrendered his remaining approximately 10000 troops at Appomattox Court House the following morning. Jefferson Davis retreated to North Carolina, then further south. when Lincoln rejected the surrender terms negotiated by general Sherman and envoys of North Carolina governor Zebulon Vance, which failed to mention slavery. Davis was captured on May 10 near Irwinville, Georgia and taken back to Virginia, where he was charged with treason and imprisoned for two years at Fort Monroe until freed on bail.
What was the date before the day Lincoln entered Richmond?
A: April 3

Context and question: A local industry manufacturing fibre from New Zealand flax was successfully reestablished in 1907 and generated considerable income during the First World War. Ascension Island was made a dependency of Saint Helena in 1922, and Tristan da Cunha followed in 1938. During the Second World War, the United States built Wideawake airport on Ascension in 1942, but no military use was made of Saint Helena.
What country does the local industry that manufactures fibre get their flax from?
Answer: New Zealand

Question: The alkali metal ions are small and mobile; their presence in glass allows a degree of electrical conductivity, especially in molten state or at high temperature. Their mobility decreases the chemical resistance of the glass, allowing leaching by water and facilitating corrosion. Alkaline earth ions, with their two positive charges and requirement for two non-bridging oxygen ions to compensate for their charge, are much less mobile themselves and also hinder diffusion of other ions, especially the alkalis. The most common commercial glasses contain both alkali and alkaline earth ions (usually sodium and calcium), for easier processing and satisfying corrosion resistance. Corrosion resistance of glass can be achieved by dealkalization, removal of the alkali ions from the glass surface by reaction with e.g. sulfur or fluorine compounds. Presence of alkaline metal ions has also detrimental effect to the loss tangent of the glass, and to its electrical resistance; glasses for electronics (sealing, vacuum tubes, lamps...) have to take this in account.
Is there an answer to this question: How can glass be prevented from diffusing?

Answer: unanswerable

QUES: Thus, Buckingham Palace is a symbol and home of the British monarchy, an art gallery and a tourist attraction. Behind the gilded railings and gates which were completed by the Bromsgrove Guild in 1911 and Webb's famous facade, which has been described in a book published by the Royal Collection as looking "like everybody's idea of a palace", is not only a weekday home of the Queen and Prince Philip but also the London residence of the Duke of York and the Earl and Countess of Wessex. The palace also houses the offices of the Queen, Prince Philip, Duke of York, Earl and Countess of Wessex, Princess Royal, and Princess Alexandra, and is the workplace of more than 800 people.
