Q: Often, sexual orientation and sexual orientation identity are not distinguished, which can impact accurately assessing sexual identity and whether or not sexual orientation is able to change; sexual orientation identity can change throughout an individual's life, and may or may not align with biological sex, sexual behavior or actual sexual orientation. While the Centre for Addiction and Mental Health and American Psychiatric Association state that sexual orientation is innate, continuous or fixed throughout their lives for some people, but is fluid or changes over time for others, the American Psychological Association distinguishes between sexual orientation (an innate attraction) and sexual orientation identity (which may change at any point in a person's life).

A: What can impact accurately assesing sexual identity?

Q: A day after announcing the attempt on his life, Nasser established a new provisional constitution proclaiming a 600-member National Assembly (400 from Egypt and 200 from Syria) and the dissolution of all political parties. Nasser gave each of the provinces two vice-presidents: Boghdadi and Amer in Egypt, and Sabri al-Asali and Akram al-Hawrani in Syria. Nasser then left for Moscow to meet with Nikita Khrushchev. At the meeting, Khrushchev pressed Nasser to lift the ban on the Communist Party, but Nasser refused, stating it was an internal matter which was not a subject of discussion with outside powers. Khrushchev was reportedly taken aback and denied he had meant to interfere in the UAR's affairs. The matter was settled as both leaders sought to prevent a rift between their two countries.

A: How many members were in the National Assembly?

Q: The first Europeans to disembark and explore the region were the Portuguese navigators Diogo Cão in 1485 and Bartolomeu Dias in 1486; still the region was not claimed by the Portuguese crown. However, like most of Sub-Saharan Africa, Namibia was not extensively explored by Europeans until the 19th century, when traders and settlers arrived, principally from Germany and Sweden. In the late 19th century Dorsland trekkers crossed the area on their way from the Transvaal to Angola. Some of them settled in Namibia instead of continuing their journey.

A:
What nationality were the first navigators to explore Namibia come from?
