Pressure groups - 'Double Agent' activity

Here's a resource that a teacher can run as a 10-15 minute small-team activity or allow students to complete themselves online.

'Double Agent' imagines that you have 3 secret agents. One of these is acting as a double agent and needs to be found out. All 3 agents are asked 10 questions and each gives a different answers. The genuine agents always give true answers. The double agent, however, will give some incorrect answers (but not all of the time!).

Students have to work out the 'truths' from the 'lies'.
