What caused the united states congress to pass an act designed to economically isolate south africa in 1986?

Apartheid

Explanation:

During these years, South Africa was living under a policy of apartheid. This was a legal system that segregated black and white people in all aspects of life. This discrimination was seen as cruel and inhumane by the United States, and it led to the country implementing sanctions against South Africa through the Comprehensive Anti-Apartheid Act of 1986.

b. after i get up in the morning,

explanation:

after is a subordinating conjunction that introduces a time clause. time clauses are dependent clauses used to indicate when something happened.

the clause "after i get up in the morning" tells when the action in the main clause (drinking a cup of coffee) happens:

"after i get up in the morning, i drink a cup of coffee." it is the most logical choice of all.
