1. Contrast structure: The use of "not easy, but..." shows a clear contrast, which is a great way to develop ideas in IELTS Speaking Part 3.
2. Present simple tense: Most of the answer uses the present simple tense (e.g., "doctors have the chance," "they are highly respected"), which is appropriate for talking about general truths and opinions.
3. Complex sentences: The answer uses complex sentences with clauses (e.g., "Although the challenges are huge, like long hours and high stress, doctors have the chance...") to add depth and detail.
4. Passive voice: "They are highly respected in society" uses passive voice, which is a good way to vary sentence structure and show grammatical range.
