Lo siento, no se la respuesta, desearia poder ayudarte a tener un buen dia. :D
Gorbachev pursued glasnost and perestroika reforms because the Soviet economy could not keep up with the arms race. The correct option among all the options that are given in the question is the first option. The war of Afghanistan was proving a bit heavy on the Soviet economy. To stabilize the economy, Gorbachev pursued such policies.
1. exploitation of foreign regions for natural resources2. promotion of white superiority3. the spread of English language in South Asia (although European Imperialism was mentioned in the question and not British)
I would say the last one, the colonist were better supplied and had superior training :)
Economic support would be most likely the main reason
