Ex Input:
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.

Ex Output:
What was proposed for the abbey in June 2009?


Ex Input:
As early as 1934, Popper wrote of the search for truth as "one of the strongest motives for scientific discovery." Still, he describes in Objective Knowledge (1972) early concerns about the much-criticised notion of truth as correspondence. Then came the semantic theory of truth formulated by the logician Alfred Tarski and published in 1933. Popper writes of learning in 1935 of the consequences of Tarski's theory, to his intense joy. The theory met critical objections to truth as correspondence and thereby rehabilitated it. The theory also seemed, in Popper's eyes, to support metaphysical realism and the regulative idea of a search for truth.

Ex Output:
Whose theory of truth did Popper read with intense interest in 1935?


Ex Input:
A plethora of anti-aircraft gun systems of smaller calibre were available to the German Wehrmacht combined forces, and among them the 1940-origin Flakvierling quadruple-20 mm-gun antiaircraft weapon system was one of the most often-seen weapons, seeing service on both land and sea. The similar Allied smaller-calibre air-defence weapons systems of the American forces were also quite capable, although they receive little attention. Their needs could cogently be met with smaller-calibre ordnance beyond using the usual singly-mounted M2 .50 caliber machine gun atop a tank's turret, as four of the ground-used "heavy barrel" (M2HB) guns were mounted together on the American Maxson firm's M45 Quadmount weapons system (as a direct answer to the Flakvierling),which were often mounted on the back of a half-track to form the Half Track, M16 GMC, Anti-Aircraft. Although of less power than Germany's 20 mm systems, the typical 4 or 5 combat batteries of an Army AAA battalion were often spread many kilometers apart from each other, rapidly attaching and detaching to larger ground combat units to provide welcome defence from enemy aircraft.

Ex Output:

What was one of the most often seen weapons that was used both on land and sea?
