Here’s how each sentence aligns with the point, evidence, and analysis:
Point: The writer presents teaching as a tough profession which tests your resilience on a daily basis.
Evidence: The writer says teachers are often “tough as nails” because you have to work long hours and your salary does not often reflect the often “emotional and physical demands” of the job.
Analysis: By using the simile “tough as nails”, the writer emphasises how mentally and physically strong an individual needs to be in order to survive and succeed as a teacher.
