Which method is NOT a way to test understanding?

The correct choice identifies a method that does not effectively test understanding. Listening actively involves paying attention to the speaker, which is crucial for comprehension, but it does not inherently test whether understanding has been achieved. Testing understanding typically involves engaging in a dialogue or feedback process that confirms comprehension.

Paraphrasing involves restating what someone else has said in your own words, which can demonstrate that you understand the message clearly and help the speaker confirm or clarify their points. Clarifying entails asking questions to gain further understanding of a topic, allowing for deeper insight and confirming comprehension. Parroting, on the other hand, refers to the act of repeating what someone has said without processing or reflecting on its meaning. It suggests an inability to engage with the content critically, rather than testing understanding.

Thus, while listening actively is essential for the exchange of information, it alone does not serve as a method for testing one's understanding of that information.
