1. Modal verbs: The use of "should" in "governments should provide financial support" shows ability to express opinions and recommendations, which is important in IELTS Speaking Part 3.
2. Present simple tense: Most of the answer uses present simple (e.g., "Start-ups are a major source of new jobs," "They bring fresh ideas") to state general truths and facts, which is appropriate for this type of question.
3. Conditional clause: "If these start-ups succeed, they’ll contribute more in taxes" is a first conditional sentence, showing the ability to discuss possible future outcomes.
4. Infinitive of purpose: "to get funding from banks," "to stay competitive"—these show why something is done, adding clarity and detail to the answer.
