Question

how did the international community respond to south africas policies in the 1980s? by refusing to buy south african goods by setting up a blockade around the country by threatening to declare war on south africa by negotiating treaties between different groups

Explanation:

In the 1980s, the international community was critical of South Africa's apartheid policies. One of the main economic measures taken was economic sanctions, which included boycotting South African goods. A blockade was not set - up around the country. There was no serious threat of declaring war on South Africa. Negotiating treaties between different groups was more of an internal South African process (e.g., between the African National Congress and the South African government) rather than an international community response in the way described in the options.

Answer:

by refusing to buy South African goods
