Which of the following is a reader-and-task consideration in systems that measure text complexity?

Readability refers to the ease with which a reader can understand a written text, often determined by factors like sentence length and word complexity. While important, readability measures do not directly address the reader's engagement or emotional connection to the text, which limits its effectiveness as a standalone consideration in text complexity systems.

Meaning focuses on the significance and interpretation of the text itself. Although understanding meaning is vital for comprehension, it does not account for the reader's personal context or motivation, which can greatly affect their interaction with the text. Thus, while meaning is necessary, it is not a complete measure of text complexity.

Clarity relates to how clearly ideas are expressed within the text. While clarity is important for understanding, it does not take into account the reader's motivation or interest in the content. A clear text may still fail to engage a reader who lacks motivation, highlighting why clarity alone is insufficient in measuring text complexity.
