Unit 1 - Introduction: AI for Everyone

Artificial Intelligence can speed up repetitive work such as sorting data, checking records, and responding to frequently asked questions. Therefore, option A is correct because automation saves time and can reduce human effort. AI is a useful support tool, but it does not replace human judgement in every situation. Human supervision is especially important for complex, ethical, or high-risk decisions. In addition, AI outputs should be checked, and personal data must be handled with permission and care.

Many AI systems, especially machine-learning-based systems, can recognise patterns in data or examples and use them to improve predictions or decisions in similar new cases. In contrast, a simple instruction-based program follows rules written in advance by a programmer; it does not normally alter its rules from experience. Therefore, option A is correct. Option B is incorrect because an ordinary instruction-based program does not change its own rules for every new situation.
