Context and question: Since the 1970s, an important focus of study has been the ozone layer in the atmosphere above Antarctica. In 1985, three British scientists working on data they had gathered at Halley Station on the Brunt Ice Shelf discovered the existence of a hole in this layer. It was eventually determined that the destruction of the ozone was caused by chlorofluorocarbons (CFCs) emitted by human products. With the ban of CFCs in the Montreal Protocol of 1989, climate projections indicate that the ozone layer will return to 1980 levels between 2050 and 2070.
What does CCF stand for?
Answer: unanswerable
Context and question: Another group of residences, known as the Village, is located in the northwest corner of Danforth Campus. Only open to upperclassmen and January Scholars, the North Side consists of Millbrook Apartments, The Village, Village East on-campus apartments, and all fraternity houses except the Zeta Beta Tau house, which is off campus and located just northwest of the South 40. Sororities at Washington University do not have houses by their own accord. The Village is a group of residences where students who have similar interests or academic goals apply as small groups of 4 to 24, known as BLOCs, to live together in clustered suites along with non-BLOCs. Like the South 40, the residences around the Village also surround a recreational lawn.
Which North Side structure is closest to the Zeta Beta Tau fraternity house?
Answer: unanswerable
Context and question: After the assassination, Mark Antony formed an alliance with Caesar's adopted son and great-nephew, Gaius Octavian. Along with Marcus Lepidus, they formed an alliance known as the Second Triumvirate. They held powers that were nearly identical to the powers that Caesar had held under his constitution. As such, the Senate and assemblies remained powerless, even after Caesar had been assassinated. The conspirators were then defeated at the Battle of Philippi in 42 BC. Eventually, however, Antony and Octavian fought against each other in one last battle. Antony was defeated in the naval Battle of Actium in 31 BC, and he committed suicide with his lover, Cleopatra. In 29 BC, Octavian returned to Rome as the unchallenged master of the Empire and later accepted the title of Augustus ("Exalted One"). He was convinced that only a single strong ruler could restore order in Rome.
In what battle did Mark Antony see defeat?
Answer:
Battle of Actium
