Answer: The correct option is: "Children begin to use reading as a source for learning around fourth grade."
Step-by-step explanation:
In 4th grade students begin to learn how to analyze the books they read. They need to go further and not just to understand the plot and information given in a text but also to think about the messages and how they can relate it to their own lives. They also look for connections between different books. For that reason, reading becomes an excellent source for the students' learning process.
