Final answer:
Successful writing is often linked to strong reading skills since reading enhances language understanding, vocabulary, tone, and structure, all of which are essential for writing effectively.
Step-by-step explanation:
One predictor of successful writing is that the student is also good at reading. This is because reading and writing are interconnected skills. The more one engages with reading, the more they learn about language use, which in turn helps them write more effectively. Reading helps students develop a better understanding of tone, language structure, and enhances their vocabulary, all of which are critical for writing. Furthermore, exposure to a wide variety of texts can improve a student's ability to evaluate and solve completely different writing tasks by providing examples of how to structure their work and communicate ideas clearly.
