Naruto, part 4

In order to officially obtain the rank of Genin, Academy students must undergo a field evaluation administered by a Jonin, who will be their squad leader should they pass. Students are organized into groups of three Genin, with a Jonin-sensei assigned to each team. Teams are chosen to balance skills and abilities. As such, Naruto, being the worst student, was paired with Sakura Haruno and Sasuke Uchiha, with Sasuke being the brightest one and Sakura being the best at quizes and tests but not stong in subjects like stamina and taijutsu. The other teams (that would pass) were Shino Aburame, Hinata Hyuga, and Kiba Inuzuka in Team 8 and Choji Akimichi, Shikamaru Nara, and Ino Yamanaka in Team 10.

Team 7's initial group chemistry was terrible: Naruto was infatuated with Sakura and detested Sasuke, Sakura was infatuated with Sasuke and detested Naruto, and Sasuke was a lone wolf who detested the both of them. Unfortunately for them, their Jonin instructor was Kakashi Hatake, who emphasized teamwork above all else.

Kakashi's field evaluation, considered the strictest of its type, is simple but difficult; in fact, he hadn't passed anyone during his time as a Jonin. All the Genin have to do to pass is take a bell from him using any means necessary before noon. Aside from the fact that three Genin are taking on a Jonin, Kakashi only has two bells on his belt, ensuring that one of them will fail. On top of that, the students are tricked into skipping breakfast. Those who get the bells get to eat, while the one who doesn't is tied to a post. The main purpose is not to test the Genin's skill, but rather their teamwork. Team 7's performance during the exam was terrible: Naruto fell into every trap Kakashi set, not bothering to be at all stealthy about his attacks, Sakura did nothing to help, even getting tricked by Kakashi's Demonic Illusion: Hell Viewing Technique genjutsu, and Sasuke didn't bother to help either of them, instead attacking on his own because he believed they would slow him down. All three failed to get a bell.

After their failure, Kakashi berates all three for their lack of teamwork. He eventually explained to them the purpose of the exam, and allowed them to eat in preparation for a second try. Naruto, who had stumbled upon the lunches Kakashi prepared and attempted to eat them, is tied to the post. After he left, Sakura and Sasuke realized that they'll need Naruto in top-shape if they're to retrieve the bells, and decided to feed him against Kakashi's wishes. Kakashi, of course, was watching the whole time and appeared in a giant blast of smoke, appearing quite furious. The three Genin claim that they're a team, and as such one person. Quickly changing his attitude, Kakashi lets them pass for figuring out the purpose of the exam. He also recites the exact message he was trying to get across - "In the ninja world, those who don't follow the rules are trash. That is true, but those who abandon their friends are worse than trash."
