[Q]: Question: "The highest use of copper, percentage wise, is in what?" Context: "The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is mostly used as a pure metal, but when a higher hardness is required it is combined with other elements to make an alloy (5% of total use) such as brass and bronze. A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics." Answer:

[Q]: Question: "Who does not benefit of a point-of foul infraction?" Context: "Penalties never result in a score for the offence. For example, a point-of-foul infraction committed by the defence in their end zone is not ruled a touchdown, but instead advances the ball to the one-yard line with an automatic first down. For a distance penalty, if the yardage is greater than half the distance to the goal line, then the ball is advanced half the distance to the goal line, though only up to the one-yard line (unlike American football, in Canadian football no scrimmage may start inside either one-yard line). If the original penalty yardage would have resulted in a first down or moving the ball past the goal line, a first down is awarded." Answer:
****
[A]: offence

[Q]: Question: "What did Athanasius receive regarding non-Arians?" Context: "Constantius, renewing his previous policies favoring the Arians, banished Athanasius from Alexandria once again. This was followed, in 356, by an attempt to arrest Athanasius during a vigil service. Athanasius fled to Upper Egypt, where he stayed in several monasteries and other houses. During this period, Athanasius completed his work Four Orations against the Arians and defended his own recent conduct in the Apology to Constantius and Apology for His Flight. Constantius's persistence in his opposition to Athanasius, combined with reports Athanasius received about the persecution of non-Arians by the new Arian bishop George of Laodicea, prompted Athanasius to write his more emotional History of the Arians, in which he described Constantius as a precursor of the Antichrist." Answer:
****
[A]: reports
