1. Present simple tense: Used throughout the answer (e.g. "stress plays an important role," "stress can actually be quite motivating") to state general truths and opinions, which is appropriate for IELTS Part 3.
2. Modal verbs: "can" is used several times ("can actually be quite motivating," "can push people," "can also help") to express possibility and ability, adding nuance to the ideas.
3. Conditional structure: "when they're under a bit of pressure" is a time clause that acts like a conditional, showing under what circumstances people perform at their best.
4. Infinitive of purpose: "to prepare better and stay alert" and "to step out of their comfort zones and grow" use infinitives to explain the purpose or result of stress, making the answer more detailed and clear.
