How could the following sentence fragment be revised to make it a complex sentence?
If Percy could be a professional cook.
A
if he could be a professional cook.
B
If Percy could be a professional cook, he'd make food from everywhere in the
world.
c
After Percy became a professional cook,
D
Professional cooks from around the world.

The proper way to revise the sentence would be:

C. After Percy became a professional cook

Explanation:

The way to revise the sentence is to set up the framework for a complex statement in the use of this fragment only which is to form the first of the two or many parts of the complex sentence that is to come after it.

The complex sentence thus made would need to have interdependent parts that do not have complete meanings if they are not in direct relations with each other.

In this context one can see how the statement given here draws out another line into the sentence to make it complex.

the african society basically suffered the consequences of colonization and apartheid directly attacking the black people, first, during the colonialism and its main idea which which "white people" had better rights, affecting   them principally in the right to establish black people in their territories, access to quality education and health services and took away any civil right even to the black people to feel they have the same opportunities as the settlers.

sorry but whats the question?
