Problem: Carnival:

Carnival is celebrated in New York City in Brooklyn. As in the UK, the timing of Carnival split from the Christian calendar and is celebrated on Labor Day Monday, in September. It is called the Labor Day Carnival, West Indian Day Parade or West Indian Day Carnival, and was founded by immigrants from Trinidad. That country has one of the largest Caribbean Carnivals. In the mid twentieth century, West Indians moved the event from the beginning of Lent to the Labor Day weekend. Carnival is one of the largest parades and street festivals in New York, with over one million attending. The parade, which consists of steel bands, floats, elaborate Carnival costumes and sound trucks, proceeds along Brooklyn's Eastern Parkway in the Crown Heights neighborhood.

Problem: In addition to tributary relations with the Kushans, the Han Empire received gifts from the Parthian Empire, from a king in modern Burma, from a ruler in Japan, and initiated an unsuccessful mission to Daqin (Rome) in AD 97 with Gan Ying as emissary. A Roman embassy of Emperor Marcus Aurelius (r. 161180 AD) is recorded in the Hou Hanshu to have reached the court of Emperor Huan of Han (r. AD 146168) in AD 166, yet Rafe de Crespigny asserts that this was most likely a group of Roman merchants. Other travelers to Eastern-Han China included Buddhist monks who translated works into Chinese, such as An Shigao of Parthia, and Lokaksema from Kushan-era Gandhara, India.
When did Emperor Huan's reign begin?

Answer: AD 146

Dominic's search for a close relationship with God was determined and unceasing. He rarely spoke, so little of his interior life is known. What is known about it comes from accounts written by people near to him. St. Cecilia remembered him as cheerful, charitable and full of unceasing vigor. From a number of accounts, singing was apparently one of Dominic's great delights. Dominic practiced self-scourging and would mortify himself as he prayed alone in the chapel at night for 'poor sinners.' He owned a single habit, refused to carry money, and would allow no one to serve him.
Who did Dominic not pray for?
A: unanswerable

Context and question: Military settlement within the empire and at its borders broadened the context of Romanitas. Rome's citizen-soldiers set up altars to multiple deities, including their traditional gods, the Imperial genius and local deities sometimes with the usefully open-ended dedication to the diis deabusque omnibus (all the gods and goddesses). They also brought Roman "domestic" deities and cult practices with them. By the same token, the later granting of citizenship to provincials and their conscription into the legions brought their new cults into the Roman military.
To whom did Roman soldiers set up alters?
Answer: traditional gods

Question: It is said[by whom?] on one side of this debate that separation of powers means that powers are shared among different branches; no one branch may act unilaterally on issues (other than perhaps minor questions), but must obtain some form of agreement across branches. That is, it is argued that "checks and balances" apply to the Judicial branch as well as to the other branches.
Is there an answer to this question: The Judicial branch of government is the only one to which what is applied?

The house which forms the architectural core of the palace was built for the first Duke of Buckingham and Normanby in 1703 to the design of William Winde. The style chosen was of a large, three-floored central block with two smaller flanking service wings. Buckingham House was eventually sold by Buckingham's descendant, Sir Charles Sheffield, in 1761 to George III for 21,000. Sheffield's leasehold on the mulberry garden site, the freehold of which was still owned by the royal family, was due to expire in 1774.
How much did George III pay for the house?
A:
21,000
