Introduction to Artificial Intelligence

Correct answer: A. To develop systems that can learn, reason, and make decisions

The main purpose of artificial intelligence is to develop systems that can perform tasks associated with human intelligence, including learning, reasoning, problem-solving, and decision-making. Therefore, option A is correct. The other options describe limited applications or ordinary automation rather than the broader purpose of AI.

Correct answer: A. A rule-based system follows rules predefined by humans.

A conventional rule-based system makes decisions using explicit rules written or specified in advance by people. A learning system, such as a machine-learning system, uses data to identify patterns or relationships and improve its outputs. Therefore, option A correctly states the key distinction.

Correct answer: B. It helps identify people connected with the project and understand its impact on them

A stakeholder map identifies people or groups who affect a project or are affected by it. It helps the team understand their roles, interests, needs, and influence. Therefore, option B is correct; mapping does not automatically create a model or remove errors.

Correct answer: A. So that the solution addresses the real problem and is useful to users

Understanding users' needs helps ensure that a solution addresses the actual problem, fits the users' context, and is practical to use. This is especially important in human-centred AI. Therefore, option A is correct; the other choices ignore user needs or feedback.

Correct answer: A. To detect performance decline, errors, and data changes in real use

After deployment, an AI system works with real data and real-world conditions. Monitoring helps detect performance decline, new errors, bias, and changes in data, so the system can be improved or updated when needed. Therefore, option A is correct. Option B suggests daily retraining without need, whereas monitoring first identifies whether a problem or change has occurred.

Correct answer: A. Understanding real needs and the problem

Stakeholders are people connected with the problem, its use, or the proposed solution. Interacting with them reveals their actual needs, expectations, and context, helping the team design a more useful and suitable AI solution. Therefore, option A is correct; the other options describe ignoring information or using it incorrectly and unethically. Exam tip: During problem scoping in the AI Project Cycle, treat stakeholder input as an important primary source.
