Problem: Federal Bureau of Investigation:

Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in U.S. embassies and consulates across the globe. These overseas offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries. The FBI can and does at times carry out secret activities overseas, just as the CIA has a limited domestic function; these activities generally require coordination across government agencies.

Do LEGAT offices conduct unilateral operations in host countries?

A: not usually

Problem: Cardinal (Catholicism):

The term cardinal at one time applied to any priest permanently assigned or incardinated to a church, or specifically to the senior priest of an important church, based on the Latin cardo (hinge), meaning "principal" or "chief". The term was applied in this sense as early as the ninth century to the priests of the tituli (parishes) of the diocese of Rome. The Church of England retains an instance of this origin of the title, which is held by the two senior members of the College of Minor Canons of St Paul's Cathedral.

Which church maintains the original meaning of the Greek word "cardo"?
---
A: unanswerable


Problem: Child labour:

According to Milton Friedman, before the Industrial Revolution virtually all children worked in agriculture. During the Industrial Revolution many of these children moved from farm work to factory work. Over time, as real wages rose, parents became able to afford to send their children to school instead of work and as a result child labour declined, both before and after legislation. Austrian School economist Murray Rothbard said that British and American children of the pre- and post-Industrial Revolution lived and suffered in infinitely worse conditions where jobs were not available for them and went "voluntarily and gladly" to work in factories.

What did parents do when the wages were finally raised?
---
A:
send their children to school instead of work
