[EX Q]: It became easier to move around in non-deep water thanks to what living entity?, Context: The tide-predicting machine invented by Sir William Thomson in 1872 was of great utility to navigation in shallow waters. It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location.
[EX A]: Sir William Thomson

[EX Q]: What did the Founding Fathers intend more of?, Context: In contrast, Europe has a greater history of unitary states than North America, thus European "federalism" argues for a weaker central government, relative to a unitary state. The modern American usage of the word is much closer to the European sense. As the power of the Federal government has increased, some people have perceived a much more unitary state than they believe the Founding Fathers intended. Most people politically advocating "federalism" in the United States argue in favor of limiting the powers of the federal government, especially the judiciary (see Federalist Society, New Federalism).
[EX A]: limiting the powers of the federal government

[EX Q]: What can trustees not get?, Context: A charity is a nonprofit organisation that meets stricter criteria regarding its purpose and the method in which it makes decisions and reports its finances. For example, a charity is generally not allowed to pay its Trustees. In England and Wales, charities may be registered with the Charity Commission. In Scotland, the Office of the Scottish Charity Regulator serves the same function. Other organizations which are classified as nonprofit organizations elsewhere, such as trade unions, are subject to separate regulations, and are not regarded as "charities" in the technical sense.
[EX A]:
pay
