Section B  Read this paragraph and answer the questions. Burning fossil fuels is the main producer of greenhouse gases. To reduce this complex global problem, applying a carbon tax to coal, oil, and natural gas emissions has been successful. The aim of this tax is to limit carbon emissions, and so reduce the effects of climate change. However, few governments have introduced a carbon tax so far. Without this method to cut greenhouse gases, global temperatures are expected to rise by about 4°C above pre-industrial levels by the end of this century.
