Question: 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).
Is there an answer to this question: When are states allowed to use plenary power?

Answer: absence of constitutional or statutory provisions replacing the common law


Question: Spinal cord fibers dedicated to carrying A-delta fiber pain signals, and others that carry both A-delta and C fiber pain signals up the spinal cord to the thalamus in the brain have been identified. Other spinal cord fibers, known as wide dynamic range neurons, respond to A-delta and C fibers, but also to the large A-beta fibers that carry touch, pressure and vibration signals. Pain-related activity in the thalamus spreads to the insular cortex (thought to embody, among other things, the feeling that distinguishes pain from other homeostatic emotions such as itch and nausea) and anterior cingulate cortex (thought to embody, among other things, the motivational element of pain); and pain that is distinctly located also activates the primary and secondary somatosensory cortices. Melzack and Casey's 1968 picture of the dimensions of pain is as influential today as ever, firmly framing theory and guiding research in the functional neuroanatomy and psychology of pain.
Is there an answer to this question: Pain which is distinctly located also activates what cortices? 

Answer: somatosensory


Question: During the early 20th century it became increasingly common to bury cremated remains rather than coffins in the abbey. In 1905 the actor Sir Henry Irving was cremated and his ashes buried in Westminster Abbey, thereby becoming the first person ever to be cremated prior to interment at the abbey. The majority of interments at the Abbey are of cremated remains, but some burials still take place - Frances Challen, wife of the Rev Sebastian Charles, Canon of Westminster, was buried alongside her husband in the south choir aisle in 2014. Members of the Percy Family have a family vault, The Northumberland Vault, in St Nicholas's chapel within the abbey.
Is there an answer to this question: In the early 19th century it became more common to bury what kind of remains?

Answer: unanswerable


Question: Another term for Christians which appears in the New Testament is "Nazarenes" which is used by the Jewish lawyer Tertullus in Acts 24. Tertullian (Against Marcion 4:8) records that "the Jews call us Nazarenes," while around 331 AD Eusebius records that Christ was called a Nazoraean from the name Nazareth, and that in earlier centuries "Christians," were once called "Nazarenes." The Hebrew equivalent of "Nazarenes", Notzrim, occurs in the Babylonian Talmud, and is still the modern Israeli Hebrew term for Christian.
Is there an answer to this question: In which book of the Old Testament does Tertullus use the term Nazarenes to refer to Christians?

Answer:
unanswerable
