Zack is likely to have suffered damage to the <u>"frontal lobe"</u> of his cortex.
The frontal lobe is the piece of the cerebrum that controls vital psychological abilities in people, for example, emotional articulation, critical thinking, memory, dialect, judgment, and sexual conduct etc. It is, in simple words, the "control board" of our identity and our capacity to express ourselves.

Answer:
dialectic relationship.
Explanation:
Hegel coined the "Master-slave" dialectic for a relationship that exists where although one holds the power over the other, there is a constant and permanent bond between them. The necessity of depending on the other makes this relationship dialectical.
The slave needs the Lord for granting him the means of survival, and the Lord, in turn, needs the labour done by the slave.
Similarly, students and professors are always relying on the other for keeping the teaching & learning environment healthy, while you can depend on him for grades, the teacher must also foreseek for you well being so he can keep his job.
This is usually true.
Most commonly the hero's quest archetype has a hero who starts off as a simple man or a boy with no specific heroic skills, but eventually he/she becomes heroic and valiant, improved version of the initial self.
