Problem: Indigenous peoples of the Americas:

The territory of modern-day Mexico was home to numerous indigenous civilizations prior to the arrival of the Spanish conquistadores: The Olmecs, who flourished from between 1200 BCE to about 400 BCE in the coastal regions of the Gulf of Mexico; the Zapotecs and the Mixtecs, who held sway in the mountains of Oaxaca and the Isthmus of Tehuantepec; the Maya in the Yucatan (and into neighbouring areas of contemporary Central America); the Purepecha in present-day Michoacan and surrounding areas, and the Aztecs/Mexica, who, from their central capital at Tenochtitlan, dominated much of the centre and south of the country (and the non-Aztec inhabitants of those areas) when Hernan Cortes first landed at Veracruz.

When did the Olmecs flourish?

A: from between 1200 BCE to about 400 BCE

Problem: The Gregorian calendar is a solar calendar. A regular Gregorian year consists of 365 days, but as in the Julian calendar, in a leap year, a leap day is added to February. In the Julian calendar a leap year occurs every 4 years, but the Gregorian calendar omits 3 leap days every 400 years. In the Julian calendar, this leap day was inserted by doubling 24 February, and the Gregorian reform did not change the date of the leap day. In the modern period, it has become customary to number the days from the beginning of the month, and February 29th is often considered as the leap day. Some churches, notably the Roman Catholic Church, delay February festivals after the 23rd by one day in leap years.
When does the Julian calendar omit three leap days?

Due to the often political and cultural contours of blackness in the United States, the notion of blackness can also be extended to non-black people. Toni Morrison once described Bill Clinton as the first black President of the United States, because, as she put it, he displayed "almost every trope of blackness". Christopher Hitchens was offended by the notion of Clinton as the first black president, noting, "Mr Clinton, according to Toni Morrison, the Nobel Prize-winning novelist, is our first black President, the first to come from the broken home, the alcoholic mother, the under-the-bridge shadows of our ranking systems. Thus, we may have lost the mystical power to divine diabolism, but we can still divine blackness by the following symptoms: broken homes, alcoholic mothers, under-the-bridge habits and (presumable from the rest of [Arthur] Miller's senescent musings) the tendency to sexual predation and to shameless perjury about same." Some black activists were also offended, claiming that Clinton used his knowledge of black culture to exploit black people for political gain as no other president had before, while not serving black interests. They cite the lack of action during the Rwandan Genocide and his welfare reform, which Larry Roberts said had led to the worst child poverty since the 1960s. Others cited that the number of black people in jail increased during his administration.
Who was offended by Clinton being referred to as black?
A: Christopher Hitchens

Hitler's interest in this strategy forced Goring and Jeschonnek to review the air war against Britain in January 1941. This led to Goring and Jeschonnek agreeing to Hitler's Directive 23, Directions for operations against the British War Economy, which was published on 6 February 1941 and gave aerial interdiction of British imports by sea top priority. This strategy had been recognised before the war, but Operation Eagle Attack and the following Battle of Britain had got in the way of striking at Britain's sea communications and diverted German air strength to the campaign against the RAF and its supporting structures. The OKL had always regarded the interdiction of sea communications of less importance than bombing land-based aircraft industries.
What was Hitler's Directive 23?
A:
Directions for operations against the British War Economy
