Under the doctrine of Erie Railroad Co. v. Tompkins (1938), there is no general federal common law. Although federal courts can create federal common law in the form of case law, such law must be linked one way or another to the interpretation of a particular federal constitutional provision, statute, or regulation (which in turn was enacted as part of the Constitution or after). Federal courts lack the plenary power possessed by state courts to simply make up law, which the latter are able to do in the absence of constitutional or statutory provisions replacing the common law. Only in a few narrow limited areas, like maritime law, has the Constitution expressly authorized the continuation of English common law at the federal level (meaning that in those areas federal courts can continue to make law as they see fit, subject to the limitations of stare decisis).
Who won Erie Railroad Co. v. Tompkins?
A: unanswerable

In 1845, Ireland was hit by a potato blight. In the next four years over a million Irish people died and another million emigrated in what became known as the Great Famine. In Ireland, Victoria was labelled "The Famine Queen". She personally donated £2,000 to famine relief, more than any other individual donor, and also supported the Maynooth Grant to a Roman Catholic seminary in Ireland, despite Protestant opposition. The story that she donated only £5 in aid to the Irish, and on the same day gave the same amount to Battersea Dogs Home, was a myth generated towards the end of the 19th century.
How much did Queen Victoria actually donate to support relief in Ireland, making her the top individual donor? 
A: £2,000

Matches are held within a wrestling ring, an elevated square canvas mat with posts on each corner. A cloth apron hangs over the edges of the ring. Three horizontal ropes or cables surround the ring, suspended with turnbuckles which are connected to the posts. For safety, the ropes are padded at the turnbuckles and cushioned mats surround the floor outside the ring. Guardrails or a similar barrier enclose this area from the audience. Wrestlers are generally expected to stay within the confines of the ring, though matches sometimes end up outside the ring, and even in the audience, to add excitement.
What is used for protection in the ring?
A: For safety, the ropes are padded at the turnbuckles and cushioned mats surround the floor outside the ring.

Although theoretically a collegial body operating through consensus building, Gaddafi dominated the RCC, although some of the others attempted to constrain what they saw as his excesses. Gaddafi remained the government's public face, with the identities of the other RCC members only being publicly revealed on 10 January 1970. All young men from (typically rural) working and middle-class backgrounds, none had university degrees; in this way they were distinct from the wealthy, highly educated conservatives who previously governed the country.
On what date were the members of the RCC announced?
A:
10 January 1970
