The exact causes and motivations for Rome's military conflicts and expansions during the republic are subject to wide debate. While they can be seen as motivated by outright aggression and imperialism, historians typically take a much more nuanced view. They argue that Rome's expansion was driven by short-term defensive and inter-state factors (that is, relations with city-states and kingdoms outside Rome's hegemony), and the new contingencies that these decisions created. In its early history, as Rome successfully defended itself against foreign threats in central and then northern Italy, neighboring city-states sought the protection a Roman alliance would bring. As such, early republican Rome was not an "empire" or "state" in the modern sense, but an alliance of independent city-states (similar to the Greek hegemonies of the same period) with varying degrees of genuine independence (which itself changed over time) engaged in an alliance of mutual self-protection, but led by Rome. With some important exceptions, successful wars in early republican Rome generally led not to annexation or military occupation, but to the restoration of the way things were. But the defeated city would be weakened (sometimes with outright land concessions) and thus less able to resist Romanizing influences, such as Roman settlers seeking land or trade with the growing Roman confederacy. It was also less able to defend itself against its non-Roman enemies, which made attack by these enemies more likely. It was, therefore, more likely to seek an alliance of protection with Rome.
What did Roman settlers commonly seek out?
****
The answer: land

From European settlement in 1888, child convicts were occasionally sent to Australia where they were made to work. Child labour was not as excessive in Australia as in Britain. With a low population, agricultural productivity was higher and families did not face starvation as in established industrialised countries. Australia also did not have significant industry until the later part of the 20th century when child labour laws, and compulsory schooling had developed under the influence of Britain. From the 1870s Child labour was restricted by compulsorry schooling.
What restricted the 1870s Child labour in Australia?
****
The answer: compulsorry schooling

In a June 2008 speech, President and CEO of the New York Federal Reserve Bank Timothy Geithner—who in 2009 became Secretary of the United States Treasury—placed significant blame for the freezing of credit markets on a "run" on the entities in the "parallel" banking system, also called the shadow banking system. These entities became critical to the credit markets underpinning the financial system, but were not subject to the same regulatory controls. Further, these entities were vulnerable because of maturity mismatch, meaning that they borrowed short-term in liquid markets to purchase long-term, illiquid and risky assets. This meant that disruptions in credit markets would make them subject to rapid deleveraging, selling their long-term assets at depressed prices. He described the significance of these entities:
In a June 2008 speech, Timoty Geithner placed blame for credit market freezing on which system?
****
The answer: "parallel" banking system

Time travel is the concept of moving backwards or forwards to different points in time, in a manner analogous to moving through space, and different from the normal "flow" of time to an earthbound observer. In this view, all points in time (including future times) "persist" in some way. Time travel has been a plot device in fiction since the 19th century. Traveling backwards in time has never been verified, presents many theoretic problems, and may be an impossibility. Any technological device, whether fictional or hypothetical, that is used to achieve time travel is known as a time machine.
How long has time travel been a topic in science fiction?
****
The answer:
since the 19th century
