The problem: Answer a question about this article:
English Freemasonry spread to France in the 1720s, first as lodges of expatriates and exiled Jacobites, and then as distinctively French lodges which still follow the ritual of the Moderns. From France and England, Freemasonry spread to most of Continental Europe during the course of the 18th century. The Grande Loge de France formed under the Grand Mastership of the Duke of Clermont, who exercised only nominal authority. His successor, the Duke of Orleans, reconstituted the central body as the Grand Orient de France in 1773. Briefly eclipsed during the French Revolution, French Freemasonry continued to grow in the next century.
When did Freemasonry begin to spread to continental Europe?
****
The answer: 18th century

Problem: Please answer a question about the following article about Gramophone record:
Contrary to popular belief, if placed properly and prepared-for, drums could be effectively used and heard on even the earliest jazz and military band recordings. The loudest instruments such as the drums and trumpets were positioned the farthest away from the collecting horn. Lillian Hardin Armstrong, a member of King Oliver's Creole Jazz Band, which recorded at Gennett Records in 1923, remembered that at first Oliver and his young second trumpet, Louis Armstrong, stood next to each other and Oliver's horn could not be heard. "They put Louis about fifteen feet over in the corner, looking all sad." For fading instrumental parts in and out while recording, some performers were placed on a moveable platform, which could draw the performer(s) nearer or further away as required.[citation needed]
Where were loud instruments best placed for good sound quality?
A: farthest away from the collecting horn

Question: Read this and answer the question

Mexico city primarily rests on what was Lake Texcoco. Seismic activity is frequent here. Lake Texcoco was drained starting from the 17th century. Although none of the lake waters remain, the city rests on the lake bed's heavily saturated clay. This soft base is collapsing due to the over-extraction of groundwater, called groundwater-related subsidence. Since the beginning of the 20th century the city has sunk as much as nine metres (30 feet) in some areas. This sinking is causing problems with runoff and wastewater management, leading to flooding problems, especially during the rainy season. The entire lake bed is now paved over and most of the city's remaining forested areas lie in the southern boroughs of Milpa Alta, Tlalpan and Xochimilco.

When did draining of Lake Texcoco begin?
Answer: 17th century

Input: Article: In his dissent to the majority report of the Financial Crisis Inquiry Commission, American Enterprise Institute fellow Peter J. Wallison stated his belief that the roots of the financial crisis can be traced directly and primarily to affordable housing policies initiated by HUD in the 1990s and to massive risky loan purchases by government-sponsored entities Fannie Mae and Freddie Mac. Later, based upon information in the SEC's December 2011 securities fraud case against 6 ex-executives of Fannie and Freddie, Peter Wallison and Edward Pinto estimated that, in 2008, Fannie and Freddie held 13 million substandard loans totaling over $2 trillion.

Now answer this question: Which government-sponsored entities had massive risky loan purchases?

Output:
Fannie Mae and Freddie Mac
