Answer:
problem-cause-solution format.
Explanation:
Presentation can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.
A problem-cause-solution format is a type of speech which involves describing a problem, identifying the probable cause of the problem and lastly proffering a solution to the problem. The speaker describes a problem and proffers a solution using signal words such as dilemma, solve, problem, etc.
Hence, a method of speech or presentation organization that describes a problem and then proposes an answer to the problem is problem-cause-solution.
