Everything you need to write and speak effectively
Initiate and participate effectively in a range of collaborative discussions with diverse partners; build on the ideas of others and express own ideas clearly and persuasively.
You should also be aware of who you are speaking or writing to. You wouldn't want to give a speech about greenhouse gas emissions ruining the environment to a group of fossil fuel executives, for example. If you did, you would have to use different persuasive techniques than if you were talking to a group of Environmentalists.
