Problem: Copper:

Copper is biostatic, meaning bacteria will not grow on it. For this reason it has long been used to line parts of ships to protect against barnacles and mussels. It was originally used pure, but has since been superseded by Muntz metal. Similarly, as discussed in copper alloys in aquaculture, copper alloys have become important netting materials in the aquaculture industry because they are antimicrobial and prevent biofouling, even in extreme conditions and have strong structural and corrosion-resistant properties in marine environments.

What is copper alloys rarely used to make in the agriculture industry?

Presbyterianism is a part of the Reformed tradition within Protestantism which traces its origins to the British Isles. Presbyterian churches derive their name from the presbyterian form of church government, which is governed by representative assemblies of elders. Many Reformed churches are organized this way, but the word "Presbyterian," when capitalized, is often applied uniquely to the churches that trace their roots to the Scottish and English churches that bore that name and English political groups that formed during the English Civil War. Presbyterian theology typically emphasizes the sovereignty of God, the authority of the Scriptures, and the necessity of grace through faith in Christ. Presbyterian church government was ensured in Scotland by the Acts of Union in 1707 which created the kingdom of Great Britain. In fact, most Presbyterians found in England can trace a Scottish connection, and the Presbyterian denomination was also taken to North America mostly by Scots and Scots-Irish immigrants. The Presbyterian denominations in Scotland hold to the theology of John Calvin and his immediate successors, although there are a range of theological views within contemporary Presbyterianism. Local congregations of churches which use presbyterian polity are governed by sessions made up of representatives of the congregation (elders); a conciliar approach which is found at other levels of decision-making (presbytery, synod and general assembly).
In 1807 The Acts of Union ensured the Presbyterian church government in which country?

Question: Canadian football has mostly been confined to Canada, with the United States being the only other country to have hosted a high-level Canadian football game. The CFL's controversial "South Division" as it would come to be officially known attempted to put CFL teams in the United States playing under Canadian rules between 1992 and 1995. The move was aborted after three years; the Baltimore Stallions were the most successful of the numerous Americans teams to play in the CFL, winning the 83rd Grey Cup. Continuing financial losses, a lack of proper Canadian football venues, a pervasive belief that the American teams were simply pawns to provide the struggling Canadian teams with expansion fee revenue, and the return of the NFL to Baltimore prompted the end of Canadian football on the American side of the border.
Is there an answer to this question: How was it believed that the CFL was used to help struggling Canadian teams?
