Both authors present their arguments for or against nuclear power as factual. Which of the following quotes is referenced to a specific source? A nuclear accident at the Indian Point 3 plant would cause an estimated 50,000 "peak fatalities." The overall "nuclear cycle" produces significant greenhouse gas emissions that contribute to global warming. Nuclear energy is already cost-competitive, and trends point to falling nuclear prices and rising fossil fuel prices. Based on 12,500 reactor years of experience, nuclear power is the safest large-scale source of energy.

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 Africa's 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. The heavy levels of soot from the electrical plant upwind of Soweto, along with dust from gigantic mine dumps from gold and coal mines, created particulate pollution more than three times the recommended level. This resulted in ________. high levels of birth defects increased incidence of lung disease high levels of heart disease enriched agricultural fields and increased crop yields problems with running local automobiles and other machinery

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 Africa's 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. gas-powered home generators charcoal and candles natural gas and solar cells wood and coal natural gas and backyard windmills

wood and coal
