Answer:
Based on the description of the poster, the two persuasive techniques used are:
Fear over a possible outcome: The poster uses the fear of production loss to persuade the viewer to make every minute count. It suggests that wasting 60 minutes a day could lead to a year of production loss in 3,650 ships, which could be detrimental to the war effort.
Association with a positive idea: The poster associates the idea of punctuality and efficiency (making every minute count) with victory in the war. This positive association is meant to motivate the viewer to be more productive.
