Final answer:
Repetition is a key factor for effectively reaching populations with low literacy, as it helps reinforce and ensure recall of information. Supporting claims with convincing evidence, such as using examples and analogies, also enhances understanding and retention of the material.
Step-by-step explanation:
A key factor in reaching populations with low literacy is B. Repetition. This tactic ensures that the message is reinforced and more likely to be remembered. By repeatedly presenting information, individuals are more likely to internalize and recall it when needed.
Effective communication strategies often involve supporting claims with convincing evidence. This includes using rhetorical devices such as repetition and providing examples or scenarios that help illustrate a point. For instance, when educators are teaching health-related concepts to an audience with varying literacy levels, integrating relatable anecdotes, simplifying complex statistics with analogies, or using visual aids can enhance understanding and retention.
Furthermore, providing examples strategically throughout instructional materials can assist in interpreting and solving problems by showing step-by-step processes. This method not only aids comprehension but also allows students to apply the knowledge in practical, real-world contexts. Use of analogies can also make complex subjects more accessible by comparing them to familiar situations.
