Problem: Artifacts from the Paleolithic suggest that the moon was used to reckon time as early as 6,000 years ago. Lunar calendars were among the first to appear, either 12 or 13 lunar months (either 354 or 384 days). Without intercalation to add days or months to some years, seasons quickly drift in a calendar based solely on twelve lunar months. Lunisolar calendars have a thirteenth month added to some years to make up for the difference between a full year (now known to be about 365.24 days) and a year of just twelve lunar months. The numbers twelve and thirteen came to feature prominently in many cultures, at least partly due to this relationship of months to years. Other early forms of calendars originated in Mesoamerica, particularly in ancient Mayan civilization. These calendars were religiously and astronomically based, with 18 months in a year and 20 days in a month.
Where did some of the other early forms of calendars originate?
The answer is the following: Mesoamerica

With which team did Barcelona have a 1-1 draw in the 2015-16 Copa del Rey?

Problem: The Spanish language has been present in what is now the United States since the 16th and 17th centuries, with the arrival of Spanish colonization in North America that would later become the states of Florida, Texas, Colorado, New Mexico, Arizona, Nevada, Utah, and California. The Spanish explorers explored areas of 42 future U.S. states leaving behind a varying range of Hispanic legacy in the North American continent. Additionally, western regions of the Louisiana Territory were under Spanish rule between 1763 to 1800, after the French and Indian War, further extending the Spanish influence throughout modern-day United States of America.
Did the Spanish conquer land in the United States?
The answer is the following: Spanish colonization in North America that would later become the states of Florida, Texas, Colorado, New Mexico, Arizona, Nevada, Utah, and California.

Problem: The Bronze Age arrived circa 1500 BC when people in the region were turning copper into bronze, growing rice and domesticating poultry and pigs; they were among the first people in the world to do so. Human remains and artifacts from this era were discovered in Monywa District in the Sagaing Division. The Iron Age began around 500 BC with the emergence of iron-working settlements in an area south of present-day Mandalay. Evidence also shows the presence of rice-growing settlements of large villages and small towns that traded with their surroundings as far as China between 500 BC and 200 AD. Iron Age Burmese cultures also had influences from outside sources such as India and Thailand, as seen in their funerary practices concerning child burials. This indicates some form of communication between groups in Myanmar and other places, possibly through trade.
What events punctuate the beginning of the Iron Age?
The answer is the following:
with the emergence of iron-working settlements in an area south of present-day Mandalay
