Problem: The Roman Empire came to dominate the entire Mediterranean basin in a vast empire based on Roman law and Roman legions. It promoted trade, tolerance, and Greek culture. By 300 AD the Roman Empire was divided into the Western Roman Empire based in Rome, and the Eastern Roman Empire based in Constantinople. The attacks of the Germanic peoples of northern Europe led to the Fall of the Western Roman Empire in AD 476, a date which traditionally marks the end of the classical period and the start of the Middle Ages.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
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? 
A: bourgeois stores


Context and question: Although there is evidence of scattered Brythonic settlements in the area, the first major settlement was founded by the Romans after the invasion of 43 AD. This lasted only until around 61, when the Iceni tribe led by Queen Boudica stormed it, burning it to the ground. The next, heavily planned, incarnation of Londinium prospered, and it superseded Colchester as the capital of the Roman province of Britannia in 100. At its height in the 2nd century, Roman London had a population of around 60,000.
What was Roman London's population in the 2nd century?
Answer: around 60,000


Question: Sixteen was held to be the minimum permissible age in the 1988 Supreme Court decision of Thompson v. Oklahoma. The Court, considering the case Roper v. Simmons in March 2005, found the execution of juvenile offenders unconstitutional by a 5–4 margin, effectively raising the minimum permissible age to 18. State laws have not been updated to conform with this decision. In the American legal system, unconstitutional laws do not need to be repealed; instead, they are held to be unenforceable. (See also List of juvenile offenders executed in the United States)
Is there an answer to this question:  In what month and year was Roper v. Simmons postponed?

Answer: unanswerable


Problem: Myocardial infarction:

Shortness of breath occurs when the damage to the heart limits the output of the left ventricle, causing left ventricular failure and consequent pulmonary edema. Other symptoms include diaphoresis (an excessive form of sweating), weakness, light-headedness, nausea, vomiting, and palpitations. These symptoms are likely induced by a massive surge of catecholamines from the sympathetic nervous system, which occurs in response to pain and the blood flow abnormalities that result from dysfunction of the heart muscle. Loss of consciousness (due to inadequate blood flow to the brain and cardiogenic shock) and sudden death (frequently due to the development of ventricular fibrillation) can occur in MIs.

What kind of shock can cause sudden death?
