Problem: The end of the Dark Ages is traditionally dated to 776 BC, the year of the first Olympic Games. The Iliad and the Odyssey, the foundational texts of Western literature, are believed to have been composed by Homer in the 8th or 7th centuries BC With the end of the Dark Ages, there emerged various kingdoms and city-states across the Greek peninsula, which spread to the shores of the Black Sea, Southern Italy (Latin: Magna Graecia, or Greater Greece) and Asia Minor. These states and their colonies reached great levels of prosperity that resulted in an unprecedented cultural boom, that of classical Greece, expressed in architecture, drama, science, mathematics and philosophy. In 508 BC, Cleisthenes instituted the world's first democratic system of government in Athens.
The literary work "The Odyssey:, was written by whom?
The answer is the following: Homer

Problem: In the Battle of Cowan's Ford, Cornwallis met resistance along the banks of the Catawba River at Cowan's Ford on February 1, 1781, in an attempt to engage General Morgan's forces during a tactical withdrawal. Morgan had moved to the northern part of the state to combine with General Greene's newly recruited forces. Generals Greene and Cornwallis finally met at the Battle of Guilford Courthouse in present-day Greensboro on March 15, 1781. Although the British troops held the field at the end of the battle, their casualties at the hands of the numerically superior Continental Army were crippling. Following this "Pyrrhic victory", Cornwallis chose to move to the Virginia coastline to get reinforcements, and to allow the Royal Navy to protect his battered army. This decision would result in Cornwallis' eventual defeat at Yorktown, Virginia, later in 1781. The Patriots' victory there guaranteed American independence.
What is the present day name of the city that the Battle of Guilford Courthouse was fought at?
The answer is the following: Greensboro

Problem: Although the number of base-pairs of DNA in the human genome has been known since the 1960s, the estimated number of genes has changed over time as definitions of genes, and methods of detecting them have been refined. Initial theoretical predictions of the number of human genes were as high as 2,000,000. Early experimental measures indicated there to be 50,000–100,000 transcribed genes (expressed sequence tags). Subsequently, the sequencing in the Human Genome Project indicated that many of these transcripts were alternative variants of the same genes, and the total number of protein-coding genes was revised down to ~20,000 with 13 genes encoded on the mitochondrial genome. Of the human genome, only 1–2% consists of protein-coding genes, with the remainder being 'noncoding' DNA such as introns, retrotransposons, and noncoding RNAs.
Since when has the number of base pairs of DNA in the human genome been known?
The answer is the following: the 1960s

Problem: The Grands Magasins Dufayel was a huge department store with inexpensive prices built in 1890 in the northern part of Paris, where it reached a very large new customer base in the working class. In a neighborhood with few public spaces, it provided a consumer version of the public square. It educated workers to approach shopping as an exciting social activity not just a routine exercise in obtaining necessities, just as the bourgeoisie did at the famous department stores in the central city. Like the bourgeois stores, it helped transform consumption from a business transaction into a direct relationship between consumer and sought-after goods. Its advertisements promised the opportunity to participate in the newest, most fashionable consumerism at reasonable cost. The latest technology was featured, such as cinemas and exhibits of inventions like X-ray machines (that could be used to fit shoes) and the gramophone.
What sort of stores were The Grands Magasins Dufayel compared to? 
The answer is the following:
bourgeois stores
