Ninjas used many different tools and weapons to get the job done. They used throwing stars, bows, and acid-spurting tubes to name a few. But the favorite weapon of most ninjas may have been the katana. The katana is a long, curved sword with a single blade and a long grip to accommodate two hands. This sword was often carried in a sheath or scabbard on the ninja's back. Though the sword was primarily used for fighting and killing, the scabbard served other purposes too. The ninja could remove the sword, angle the scabbard against a wall, and use it to climb to a higher place. Or, while stealthy negotiating their way through a dark place (such as an enemy's residence at night), ninjas may have used the scabbard as a walking stick, feeling or probing their way around objects so as not to knock into anything and alert the enemy. Perhaps the ninja's most sinister use of the scabbard was to put a mixture of red pepper, dirt, and iron shavings at the top of the scabbard. Then, when the ninja drew his sword, his opponent would be blinded. I wonder what a ninja could have done with a Swiss Army knife. Read the short passage above. What is the best summary of the story? A) Ninjas used many weapons. The katana was a powerful fighting sword, but the scabbard was used as a climbing tool, probing tool, and a blinding weapon. B) The katana was a Ninjas favorite weapon. C) Katanas and Swiss Army knives were the most popular weapons used by the Ninjas. D) People think that ninjas had superpowers because ninjas have been portrayed this way in art and media.
