The problem: Answer a question about this article:
The US ended World War I with two 3-inch AA guns and improvements were developed throughout the inter-war period. However, in 1924 work started on a new 105 mm static mounting AA gun, but only a few were produced by the mid-1930s because by this time work had started on the 90 mm AA gun, with mobile carriages and static mountings able to engage air, sea and ground targets. The M1 version was approved in 1940. During the 1920s there was some work on a 4.7-inch which lapsed, but revived in 1937, leading to a new gun in 1944.
When were improvements developed for these guns?
****
The answer: throughout the inter-war period

Problem: Please answer a question about the following article about 2008 Sichuan earthquake:
The Longmen Shan Fault System is situated in the eastern border of the Tibetan Plateau and contains several faults. This earthquake ruptured at least two imbricate structures in Longmen Shan Fault System, i.e. the Beichuan Fault and the GuanxianAnxian Fault. In the epicentral area, the average slip in Beichuan Fault was about 3.5 metres (11 ft) vertical, 3.5 metres (11 ft) horizontal-parallel to the fault, and 4.8 metres (16 ft) horizontal-perpendicular to the fault. In the area about 30 kilometres (19 mi) northeast of the epicenter, the surface slip on Beichuan Fault was almost purely dextral strike-slip up to about 3 metres (9.8 ft), while the average slip in GuanxianAnxian Fault was about 2 metres (6 ft 7 in) vertical and 2.3 metres (7 ft 7 in) horizontal.
How large was the slip 30 km northeast of the fault?
A: 3 metres

On October 9, 2006 at 6:00 a.m., the network switched to a 24-hour schedule, becoming one of the last major English-language broadcasters to transition to such a schedule. Most CBC-owned stations previously signed off the air during the early morning hours (typically from 1:00 a.m. to 6:00 a.m.). Instead of the infomercials aired by most private stations, or a simulcast of CBC News Network in the style of BBC One's nightly simulcast of BBC News Channel, the CBC uses the time to air repeats, including local news, primetime series, movies and other programming from the CBC library. Its French counterpart, Ici Radio-Canada Tele, still signs off every night.

What did private stations air when programming was not ticketed?
Answer: infomercials

Problem: Yale's residential college system was established in 1933 by Edward S. Harkness, who admired the social intimacy of Oxford and Cambridge and donated significant funds to found similar colleges at Yale and Harvard. Though Yale's colleges resemble their English precursors organizationally and architecturally, they are dependent entities of Yale College and have limited autonomy. The colleges are led by a master and an academic dean, who reside in the college, and university faculty and affiliates comprise each college's fellowship. Colleges offer their own seminars, social events, and speaking engagements known as "Master's Teas," but do not contain programs of study or academic departments. Instead, all undergraduate courses are taught by the Faculty of Arts and Sciences and are open to members of any college.
Are there academic programs in Yale's residential colleges?
The answer is the following: do not contain programs of study or academic departments

According to Joshua Baron a "researcher, lecturer, and consultant on international conflict" since the early 1960s direct military conflicts and major confrontations have "receded into the background" with regards to relations among the great powers. Baron argues several reasons why this is the case, citing the unprecedented rise of the United States and its predominant position as the key reason. Baron highlights that since World War Two no other great power has been able to achieve parity or near parity with the United States, with the exception of the Soviet Union for a brief time. This position is unique among the great powers since the start of the modern era (the 16th century), where there has traditionally always been "tremendous parity among the great powers". This unique period of American primacy has been an important factor in maintaining a condition of peace between the great powers.
Since what time has military conflicts receded?
1960s
