1. Conditional sentences: The answer uses a first conditional structure ("If a company is vital... then temporary government support can be justified") to explain under what circumstances support is appropriate.
2. Passive voice: "can be justified" and "should be strictly regulated" use the passive voice, which is common in formal and semi-formal spoken English, especially when focusing on actions rather than the actor.
3. Modality: The use of modal verbs like "should," "can," and "isn't" (for "is not") shows ability, necessity, and negation, which adds nuance to the answer.
4. Cohesive devices: Words like "however" and "so" are used to connect ideas smoothly and logically, which is important for coherence in IELTS Speaking Part 3 answers.
