Multiple Choice

Read the following scenario and answer the question below.
In Johannesburg, South Africa, the South West Township (Soweto) was one of several areas established early in the last century for blacks to live away from the white ruling minority. On the hills surrounding Soweto, the company that provides South Africaʹs electricity, Eskom, built a large, coal-burning, electricity-generating plant. The electricity was for white areas of Johannesburg, miles away from the plant. The residents of Soweto had no electrical connections.
-Along with many other governmental reforms that began in 1994, the electrical plant just outside Soweto was closed in 2000 and other plants were brought into use. Some parts of Soweto were then wired for electricity. It is estimated, however, that only about 30% of the more than 1 million black inhabitants have electricity in their homes; the remainder cannot afford the costs involved or live in areas that have no electrical access. So, they probably use ________________ for fuel.
