Question: With the Conference of Berlin of 1884, Portuguese Africa territories had their borders formally established on request of Portugal in order to protect the centuries-long Portuguese interests in the continent from rivalries enticed by the Scramble for Africa. Portuguese Africa's cities and towns like Nova Lisboa, Sá 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, Moçâmedes, Lobito, João Belo, Nacala and Porto Amélia 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.
Is there an answer to this question: When were railroad tracks being installed Portugese Africa?

Answer: before the turn of the 20th century

Question: Other developmental and reproductive variations include haplodiploidy, polymorphism, paedomorphosis or peramorphosis, sexual dimorphism, parthenogenesis and more rarely hermaphroditism.:143 In haplodiploidy, which is a type of sex-determination system, the offspring's sex is determined by the number of sets of chromosomes an individual receives. This system is typical in bees and wasps. Polymorphism is where a species may have different morphs or forms, as in the oblong winged katydid, which has four different varieties: green, pink and yellow or tan. Some insects may retain phenotypes that are normally only seen in juveniles; this is called paedomorphosis. In peramorphosis, an opposite sort of phenomenon, insects take on previously unseen traits after they have matured into adults. Many insects display sexual dimorphism, in which males and females have notably different appearances, such as the moth Orgyia recens as an exemplar of sexual dimorphism in insects.
Is there an answer to this question: Polymophism species have different forms or what else?

Answer: morphs


Question: At the Abbey Saint-Denis, Noyon Cathedral, Notre Dame de Paris and at the eastern end of Canterbury Cathedral in England, simple cylindrical columns predominate over the Gothic forms of clustered columns and shafted piers. Wells Cathedral in England, commenced at the eastern end in 1175, was the first building in which the designer broke free from Romanesque forms. The architect entirely dispensed with the round arch in favour of the pointed arch and with cylindrical columns in favour of piers composed of clusters of shafts which lead into the mouldings of the arches. The transepts and nave were continued by Adam Locke in the same style and completed in about 1230. The character of the building is entirely Gothic. Wells Cathedral is thus considered the first truly Gothic cathedral.
Is there an answer to this question: When was the construction of Wells Cathedral in England halted?

Answer:
unanswerable
