Problem: Philosophy of space and time:

In Book 11 of St. Augustine's Confessions, he ruminates on the nature of time, asking, "What then is time? If no one asks me, I know: if I wish to explain it to one that asketh, I know not." He goes on to comment on the difficulty of thinking about time, pointing out the inaccuracy of common speech: "For but few things are there of which we speak properly; of most things we speak improperly, still the things intended are understood."  But Augustine presented the first philosophical argument for the reality of Creation (against Aristotle) in the context of his discussion of time, saying that knowledge of time depends on the knowledge of the movement of things, and therefore time cannot be where there are no creatures to measure its passing (Confessions Book XI ¶30; City of God Book XI ch.6).

Which christian philosopher ruminated on time?

A: St. Augustine


Problem: In June 2009 the first major building work at the abbey for 250 years was proposed. A corona—a crown-like architectural feature—was intended to be built around the lantern over the central crossing, replacing an existing pyramidal structure dating from the 1950s. This was part of a wider £23m development of the abbey expected to be completed in 2013. On 4 August 2010 the Dean and Chapter announced that, "[a]fter a considerable amount of preliminary and exploratory work", efforts toward the construction of a corona would not be continued. In 2012, architects Panter Hudspith completed refurbishment of the 14th-century food-store originally used by the abbey's monks, converting it into a restaurant with English Oak furniture by Covent Garden-based furniture makers Luke Hughes and Company.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The convention in the English language is to call nearly all national heads of government "prime minister" (sometimes modified to the equivalent term of premier), regardless of the correct title of the head of government as applied in his or her respective country. The few exceptions to the rule are Germany and Austria, whose heads of government titles are almost always translated as Chancellor; Monaco, whose head of government is referred to as the Minister of State; and Vatican City, for which the head of government is titled the Secretary of State. In the case of Ireland, the head of government is occasionally referred to as the Taoiseach by English speakers. A stand-out case is the President of Iran, who is not actually a head of state, but the head of the government of Iran. He is referred to as "president" in both the Persian and English languages.
Who is head of state and government in Iran?
A: unanswerable


Context and question: In 2011, the foundation launched a program called "Reinvent the Toilet Challenge" with the aim to promote the development of innovations in toilet design to benefit the 2.5 billion people that do not have access to safe and effective sanitation. This program has generated significant interest of the mainstream media. It was complemented by a program called "Grand Challenges Explorations" (2011 to 2013 with some follow-up grants reaching until 2015) which involved grants of US$100,000 each in the first round. Both funding schemes explicitly excluded project ideas that relied on centralized sewerage systems or are not compatible with development country contexts.
In 2011 what program was launched by Grand Challenges Exploration?
Answer: unanswerable

QUES: Within the city there have been two tram networks in operation. A proposal to develop a horse-drawn tram (linking the city's railway termini) was made by American George Francis Train in the 1860s, and implemented in 1872 by the Cork Tramway Company. However, the company ceased trading in 1875 after Cork Corporation refused permission to extend the line, mainly because of objections from cab operators to the type of tracks which – although they were laid to the Irish national railway gauge of 5 ft 3in – protruded from the road surface.[citation needed]

How tall was George Francis Train?
