Between 2000 and 2004 an average of 478 crimes were reported each day in Mexico City; however, the actual crime rate is thought to be much higher "since most people are reluctant to report crime". Under policies enacted by Mayor Marcelo Ebrard between 2009 and 2011, Mexico City underwent a major security upgrade with violent and petty crime rates both falling significantly despite the rise in violent crime in other parts of the country. Some of the policies enacted included the installation of 11,000 security cameras around the city and a very large expansion of the police force. Mexico City has one of the world's highest police officer-to-resident ratios, with one uniformed officer per 100 citizens.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the ratio of cops to citizens in Mexico City?
Ah, so.. one uniformed officer per 100 citizens

The Napoleonic Wars were the cause of the final dissolution of the Holy Roman Empire, and ultimately the cause for the quest for a German nation state in 19th-century German nationalism. After the Congress of Vienna, Austria and Prussia emerged as two competitors. Austria, trying to remain the dominant power in Central Europe, led the way in the terms of the Congress of Vienna. The Congress of Vienna was essentially conservative, assuring that little would change in Europe and preventing Germany from uniting. These terms came to a sudden halt following the Revolutions of 1848 and the Crimean War in 1856, paving the way for German unification in the 1860s. By the 1820s, large numbers of Jewish German women had intermarried with Christian German men and had converted to Christianity. Jewish German Eduard Lasker was a prominent German nationalist figure who promoted the unification of Germany in the mid-19th century.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What assured Europe would remain the same preventing Germany from becoming one country?
Ah, so.. Congress of Vienna

Gamal Abdel Nasser Hussein (Arabic: , IPA: [ml bdennse esen]; 15 January 1918 28 September 1970) was the second President of Egypt, serving from 1956 until his death. Nasser led the 1952 overthrow of the monarchy and introduced far-reaching land reforms the following year.

If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year did Nasser die?
Ah, so..
