Problem: Daylight saving time:

DST inherits and can magnify the disadvantages of standard time. For example, when reading a sundial, one must compensate for it along with time zone and natural discrepancies. Also, sun-exposure guidelines such as avoiding the sun within two hours of noon become less accurate when DST is in effect.

When using a sundial, we must adjust the reading to reflect natural discrepancies and the effect of what other influence?

A: time zone

Problem: East Prussia:

Since 1875, with the strengthening of self-rule, the urban and rural districts (Kreise) within each province (sometimes within each governorate) formed a corporation with common tasks and assets (schools, traffic installations, hospitals, cultural institutions, jails etc.) called the Provinzialverband (provincial association). Initially the assemblies of the urban and rural districts elected representatives for the provincial diets (Provinziallandtage), which were thus indirectly elected. As of 1919 the provincial diets (or as to governorate diets, the so-called Kommunallandtage) were directly elected by the citizens of the provinces (or governorates, respectively). These parliaments legislated within the competences transferred to the provincial associations. The provincial diet of East Prussia elected a provincial executive body (government), the provincial committee (Provinzialausschuss), and a head of province, the Landeshauptmann ("Land Captain"; till the 1880s titled Landdirektor, land director).

How are the assemblies of the urban and rural district positions filled from 1875 to 1919?

Problem: Eton College:

Eton College has links with some private schools in India today, maintained from the days of the British Raj, such as The Doon School and Mayo College. Eton College is also a member of the G20 Schools Group, a collection of college preparatory boarding schools from around the world, including Turkey's Robert College, the United States' Phillips Academy and Phillips Exeter Academy, Australia's Scotch College, Melbourne Grammar School and Launceston Church Grammar School, Singapore's Raffles Institution, and Switzerland's International School of Geneva. Eton has recently fostered[when?] a relationship with the Roxbury Latin School, a traditional all-boys private school in Boston, USA. Former Eton headmaster and provost Sir Eric Anderson shares a close friendship with Roxbury Latin Headmaster emeritus F. Washington Jarvis; Anderson has visited Roxbury Latin on numerous occasions, while Jarvis briefly taught theology at Eton after retiring from his headmaster post at Roxbury Latin. The headmasters' close friendship spawned the Hennessy Scholarship, an annual prize established in 2005 and awarded to a graduating RL senior for a year of study at Eton. Hennessy Scholars generally reside in Wotton house.

Who was Switzerland's International School of Geneva's headmaster in 2005?

Problem: 51st state:

Puerto Rico has been under U.S. sovereignty for over a century when it was ceded to the U.S. by Spain following the end of the SpanishAmerican War, and Puerto Ricans have been U.S. citizens since 1917. The island's ultimate status has not been determined as of 2012[update], its residents do not have voting representation in their federal government. Puerto Rico has limited representation in the U.S. Congress in the form of a Resident Commissioner, a delegate with limited no voting rights. Like the states, Puerto Rico has self-rule, a republican form of government organized pursuant to a constitution adopted by its people, and a bill of rights.

In the aftermath of which war was the U.S. granted Puerto Rico?

A:
SpanishAmerican War
