Identify the good or service you think we should tax or not tax and its price elasticity of demand coefficient. Identify the source where you found the coefficient. Make an argument for why we should tax or not tax that good or service and explain the expected outcome(s) of taxing or not taxing that good or service given its price elasticity of demand coefficient. Note that your argument may involve other aspects of tax policy, but should address the effects of the good or service's elasticity.
