Final answer:
A high-school teaching position would be a great fit for someone who wants to specialize in one subject area and become an expert in that field.
Step-by-step explanation:
If you enjoy delving into and mastering one subject area, the teaching position that might suit you best would be a high-school teacher. A high-school teacher typically specializes in a specific subject area, such as Mathematics, History, English, Biology, Chemistry, Physics, Social Studies, or World Languages. They have the opportunity to teach the same subject to multiple classes, allowing them to become experts in that particular subject.
For example, a high-school math teacher would have the chance to teach various levels of math classes, from Algebra to Calculus, therefore allowing them to delve deep into the subject and master it.
Overall, a high-school teaching position would be a great fit for someone who wants to specialize in one subject area and become an expert in that field.
