Correct answer: carbon dioxide and methane.

Explanation: Incomplete combustion of organic matter and fossil fuels releases greenhouse gases such as CO2 and, in some processes, methane (CH4). These gases trap heat in the atmosphere and drive global warming. (Note: incomplete burning can also produce carbon-containing particulates — black carbon — which absorb sunlight and also contribute to warming locally, while ethanol itself is a fuel that, when burned incompletely, yields CO and CO2 rather than acting as a greenhouse gas.)
