What choice best describes the purpose of this poster? (Choose one):

1. give civilians a government-approved version of the War

2. stop information from being spread which might help the enemy

3. encourage people to give their time and money to the war effort

Number 2. I think so because the poster is showing the cause and effect of someone talking and then something bad happening. The only one that fits that is number 2.
