Why is the underlined simile from Part I of The Odyssey effective?

"I drew it from the coals and my four fellows gave me a hand, lugging it near the Cyclops as more than natural force nerved them; straight forward they sprinted, lifted it, and rammed it deep in his crater eye, and I leaned on it turning it AS A SHIPWRIGHT TURNS A DRILL in planking, having men below to swing the two-handled strap that spins it in the groove."

O It shows that the Cyclops is as massive as a ship.
O It shows how skillfully Odysseus blinds the Cyclops.
O It shows that Odysseus used a drill to blind the Cyclops.
O It shows that Odysseus has knowledge of shipbuilding.

The correct answer is: It shows how skillfully Odysseus blinds the Cyclops. The simile of a shipwright turning a drill is effective because it conveys the skill and precision with which Odysseus is able to blind the Cyclops. It also implies that Odysseus has knowledge of shipbuilding, which adds to the effectiveness of the simile.
