Answer:
The correct answer is He heard loud noises and was curious.
Step-by-step explanation:
As soon as Henry was walking through the forest, a great rumble surprised him from a distance. The whole set of sounds he began to hear left him paralyzed.
At that moment, Henry starts running towards the battle.
He thought: "if the earth and the moon were about to clash, many persons could doubtless plan to get upon the roofs to witness the collision." This demonstrates the great curiosity he felt for what he was hearing, and that was the reason he returned.
