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.

Where did children work prior to the Industrial Revolution?

A: agriculture

Problem: Adult contemporary R&B may be played on both soft AC stations and urban AC. It is a form of neo soul R&B that places emphasis on songcraft and sophistication. As the use of drum machines, synthesizers, and sequencers dominates R&B-rooted music, adult contemporary R&B tends to take most of its cues from the more refined strains of 1970s soul, such as smooth soul, Philly soul and quiet storm. Classic songwriting touches and organic-leaning instrumentation, often featuring string arrangements and horn charts, were constants.
Along with drum machines and synthesizers, what electronic instruments are often found in modern R&B-based music?

Answer: sequencers

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
It is widely assumed that architectural success was the product of a process of trial and error, with progressively less trial and more replication as the results of the process proved increasingly satisfactory. What is termed vernacular architecture continues to be produced in many parts of the world. Indeed, vernacular buildings make up most of the built world that people experience every day. Early human settlements were mostly rural. Due to a surplus in production the economy began to expand resulting in urbanization thus creating urban areas which grew and evolved very rapidly in some cases, such as that of Catal Hoyuk in Anatolia and Mohenjo Daro of the Indus Valley Civilization in modern-day Pakistan.
At what speed did urban settlements sometimes expand?
A: rapidly

Context and question: By the 12th century, Romanesque architecture (termed Norman architecture in England because of its association with the Norman invasion), was established throughout Europe and provided the basic architectural forms and units that were to remain in evolution throughout the Medieval period. The important categories of building: the cathedral church, the parish church, the monastery, the castle, the palace, the great hall, the gatehouse, the civic building, had been established in the Romanesque period.
The Romanesque style continued to affect and inspire the basic architectural forms throughout which period?
Answer: the Medieval period

Question: The Greeks of classical antiquity idealized their Mycenaean ancestors and the Mycenaean period as a glorious era of heroes, closeness of the gods and material wealth. The Homeric Epics (i.e. Iliad and Odyssey) were especially and generally accepted as part of the Greek past and it was not until the 19th century that scholars began to question Homer's historicity. As part of the Mycenaean heritage that survived, the names of the gods and goddesses of Mycenaean Greece (e.g. Zeus, Poseidon and Hades) became major figures of the Olympian Pantheon of later antiquity.
Is there an answer to this question: What name is usually associated with the underworld?

Answer: unanswerable

USB device communication is based on pipes (logical channels). A pipe is a connection from the host controller to a logical entity, found on a device, and named an endpoint. Because pipes correspond 1-to-1 to endpoints, the terms are sometimes used interchangeably. A USB device could have up to 32 endpoints (16 IN, 16 OUT), though it's rare to have so many. An endpoint is defined and numbered by the device during initialization (the period after physical connection called "enumeration") and so is relatively permanent, whereas a pipe may be opened and closed.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where do pipes correspond?
Ah, so..
1-to-1 to endpoints
