Portuguese Africa's cities and towns like Nova Lisboa, Sa da Bandeira, Silva Porto, Malanje, Tete, Vila Junqueiro, Vila Pery and Vila Cabral were founded or redeveloped inland during this period and beyond. New coastal towns like Beira, Mocamedes, Lobito, Joao Belo, Nacala and Porto Amelia were also founded. Even before the turn of the 20th century, railway tracks as the Benguela railway in Angola, and the Beira railway in Mozambique, started to be built to link coastal areas and selected inland regions. Question: During what period were the Portugese Africa's cities founded or redeveloped?
[A]: Scramble for Africa

[Q]: Passage: The major opponent of Freemasonry was the Roman Catholic Church, so that in countries with a large Catholic element, such as France, Italy, Spain, and Mexico, much of the ferocity of the political battles involve the confrontation between what Davies calls the reactionary Church and enlightened Freemasonry.

American historians, while noting that Benjamin Franklin and George Washington were indeed active Masons, have downplayed the importance of Freemasonry in causing the American Revolution because the Masonic order was non-political and included both Patriots and their enemy the Loyalists. Question: Who was the major opponent to Freemasonry?
[A]: Roman Catholic Church
