The correct answer highlights the importance of familiarity with common language structures in assisting readers to interpret texts effectively. Understanding the structural aspects of language—such as grammar, syntax, and phrases—enables students to decode and comprehend what they are reading more efficiently. This foundational knowledge allows students to parse sentences and grasp the relationships between ideas, ultimately leading to better interpretation and analysis of various texts.

By knowing how language is typically constructed, students can recognize patterns and anticipate the meaning behind sentences or passages they encounter, thus becoming more proficient readers. This skill is crucial for navigating both academic material and literary works, where comprehension can often hinge on the reader's ability to discern these structures.

In contrast, the other choices focus on different aspects of reading and comprehension that do not directly relate to understanding language structures. Therefore, they do not capture the essential benefit highlighted in the correct answer.
