Problem: Please answer a question about the following article about Anti-aircraft warfare:
Until this time the British, at RAF insistence, continued their World War I use of machine guns, and introduced twin MG mountings for AAAD. The army was forbidden from considering anything larger than .50-inch. However, in 1935 their trials showed that the minimum effective round was an impact fused 2 lb HE shell. The following year they decided to adopt the Bofors 40 mm and a twin barrel Vickers 2-pdr (40 mm) on a modified naval mount. The air-cooled Bofors was vastly superior for land use, being much lighter than the water-cooled pom-pom, and UK production of the Bofors 40 mm was licensed. The Predictor AA No 3, as the Kerrison Predictor was officially known, was introduced with it.
What was determined to be the smallest effective round in 1935?
A: an impact fused 2 lb HE shell

Problem: After a nonprofit organization has been formed at the state level, the organization may seek recognition of tax exempt status with respect to U.S. federal income tax. That is done typically by applying to the Internal Revenue Service (IRS), although statutory exemptions exist for limited types of nonprofit organizations. The IRS, after reviewing the application to ensure the organization meets the conditions to be recognized as a tax exempt organization (such as the purpose, limitations on spending, and internal safeguards for a charity), may issue an authorization letter to the nonprofit granting it tax exempt status for income tax payment, filing, and deductibility purposes. The exemption does not apply to other Federal taxes such as employment taxes. Additionally, a tax-exempt organization must pay federal tax on income that is unrelated to their exempt purpose. Failure to maintain operations in conformity to the laws may result in an organization losing its tax exempt status.
Who has the final say on whether or not an NPO is granted tax exempt status?
The answer is the following: Internal Revenue Service (IRS)

However, with the Glorious Revolution of 1688 the Church of Scotland was finally unequivocally recognised as a Presbyterian institution by the monarch due to Scottish Presbyterian support for the aforementioned revolution and the Acts of Union 1707 between Scotland and England guaranteed the Church of Scotland's form of government. However, legislation by the United Kingdom parliament allowing patronage led to splits in the Church. In 1733, a group of ministers seceded from the Church of Scotland to form the Associate Presbytery, another group seceded in 1761 to form the Relief Church and the Disruption of 1843 led to the formation of the Free Church of Scotland. Further splits took place, especially over theological issues, but most Presbyterians in Scotland were reunited by 1929 union of the established Church of Scotland and the United Free Church of Scotland.
In what year was the Church of Scotland recognized as a Presbyterian institution by the moncarh?
1688

Input: Carnival
The term Carnival is traditionally used in areas with a large Catholic presence. However, the Philippines, a predominantly Roman Catholic country, does not celebrate Carnival anymore since the dissolution of the Manila Carnival after 1939, the last carnival in the country. In historically Lutheran countries, the celebration is known as Fastelavn, and in areas with a high concentration of Anglicans and Methodists, pre-Lenten celebrations, along with penitential observances, occur on Shrove Tuesday. In Eastern Orthodox nations, Maslenitsa is celebrated during the last week before Great Lent. In German-speaking Europe and the Netherlands, the Carnival season traditionally opens on 11/11 (often at 11:11 a.m.). This dates back to celebrations before the Advent season or with harvest celebrations of St. Martin's Day.

When does Fastelavn occur?
Output: Shrove Tuesday

Problem: Please answer a question about the following article about Han dynasty:
Timber was the chief building material during the Han dynasty; it was used to build palace halls, multi-story residential towers and halls and single-story houses. Because wood decays rapidly, the only remaining evidence of Han wooden architecture is a collection of scattered ceramic roof tiles. The oldest surviving wooden halls in China date to the Tang dynasty (618907 AD). Architectural historian Robert L. Thorp points out the scarcity of Han-era archaeological remains, and claims that often unreliable Han-era literary and artistic sources are used by historians for clues about lost Han architecture.
What dynasty can the oldest wooden buildings in China be dated to?
A:
Tang
