Which statement about shorthand is considered true?

The statement that you must understand shorthand and communicate it effectively is true because shorthand is a system designed to facilitate writing at high speeds. Mastery of shorthand requires not only the ability to write the symbols quickly but also a deep understanding of what those symbols represent. This understanding is critical when it comes to reviewing notes later or sharing the information with others. If the shorthand is not understood by the writer, or if it cannot be communicated effectively to someone else, then the purpose of its use is diminished.

In many professional contexts, shorthand serves as a tool for capturing spoken language or important information swiftly, making comprehension and communication essential aspects of its effectiveness. For it to be useful, both the writer and potential readers (such as colleagues or transcriptionists) must grasp the meaning behind the shorthand symbols.
