QUES: At birth, Victoria was fifth in the line of succession after her father and his three older brothers: the Prince Regent, the Duke of York, and the Duke of Clarence (later William IV). The Prince Regent and the Duke of York were estranged from their wives, who were both past child-bearing age, so the two eldest brothers were unlikely to have any further children. The Dukes of Kent and Clarence married on the same day 12 months before Victoria's birth, but both of Clarence's daughters (born in 1819 and 1820 respectively) died as infants. Victoria's grandfather and father died in 1820, within a week of each other, and the Duke of York died in 1827. On the death of her uncle George IV in 1830, Victoria became heiress presumptive to her next surviving uncle, William IV. The Regency Act 1830 made special provision for the Duchess of Kent to act as regent in case William died while Victoria was still a minor. King William distrusted the Duchess's capacity to be regent, and in 1836 declared in her presence that he wanted to live until Victoria's 18th birthday, so that a regency could be avoided.
What happened when Victoria's Uncle George IV died?

ANS: became heiress presumptive to her next surviving uncle

QUES: The Inequality-adjusted Human Development Index (IHDI) is a "measure of the average level of human development of people in a society once inequality is taken into account."
Does the IHDI measure the "average" or the "potential" level of human development? 

ANS: the average level

QUES: The American bison is a large bovid which inhabited much of western North America prior to the 1800s, living on the prairies in large herds. However, the vast herds of bison attracted market hunters, who killed dozens of bison for their hides only, leaving the rest to rot. Thousands of these hunters quickly eliminated the bison herds, bringing the population from several million in the early 1800s to a few hundred by the 1880s. Conservation efforts have allowed the population to increase, but the bison remains near-threatened.
What did hunter do with the rest of the bison?

ANS: leaving the rest to rot

QUES: On January 27, 1967, the same day the US and USSR signed the Outer Space Treaty, the crew of the first manned Apollo mission, Command Pilot Virgil "Gus" Grissom, Senior Pilot Edward H. White, and Pilot Roger Chaffee, were killed in a fire that swept through their spacecraft cabin during a ground test, less than a month before the planned February 21 launch. An investigative board determined the fire was probably caused by an electrical spark, and quickly grew out of control, fed by the spacecraft's pure oxygen atmosphere. Crew escape was made impossible by inability to open the plug door hatch cover against the greater-than-atmospheric internal pressure. The board also found design and construction flaws in the spacecraft, and procedural failings, including failure to appreciate the hazard of the pure-oxygen atmosphere, as well as inadequate safety procedures. All these flaws had to be corrected over the next twenty-two months until the first piloted flight could be made. Mercury and Gemini veteran Grissom had been a favored choice of Deke Slayton, NASA's Director of Flight Crew Operations, to make the first piloted landing.
Who were the three people who died on the first Apollo mission before launch?

ANS:
Command Pilot Virgil "Gus" Grissom, Senior Pilot Edward H. White, and Pilot Roger Chaffee
