Correct Answer: C. A machine's ability to exhibit intelligent behavior

• **Turing Test** = Alan Turing's benchmark to assess whether a machine can mimic human intelligence through conversation. • **Indistinguishability criterion** — evaluates if a human judge can tell the difference between machine and human dialogue. • 💡 Wrong-option analysis: A (Processing speed): measures computational power, not intelligence; B (Memory capacity): physical storage metric, not behavioral ability; D (Energy efficiency): measures hardware performance, not cognitive ability.

Correct Answer: D. Narrow AI

Correct Answer: D. Algorithm

• **Algorithm** = the logical step-by-step procedure AI models execute to process data and derive conclusions. • **Adaptive improvement** — algorithms refine themselves through exposure to more data and feedback in machine learning systems. • 💡 Wrong-option analysis: A (Database): structured data storage, not decision-making rules; B (Middleware): software layer enabling communication, not logic; C (Hardware): physical computer components, not logical procedures.

Correct Answer: A. Miming the structure of the human brain to find patterns

• **Neural networks** = computational models mimicking biological neurons in the human brain to detect patterns. • **Hierarchical information processing** — interconnected layers of nodes process data at multiple abstraction levels sequentially. • 💡 Wrong-option analysis: B (Video storage): memory management function, not pattern recognition; C (Cable connection): physical infrastructure, not computational function; D (Morse translation): linguistic decoding task, not brain-inspired architecture.

Correct Answer: C. Reinforcement Learning

• **Reinforcement learning** = AI agent learns by trial-and-error interaction with environment, receiving reward/penalty feedback. • **Reward-penalty optimization** — agents maximize cumulative rewards by refining strategy through experience and feedback loops. • 💡 Wrong-option analysis: A (Unsupervised): finds patterns in unlabeled data, no reward system; B (Data Mining): extracts knowledge from large datasets, not agent feedback; D (Expert Systems): uses rule bases, not learning from mistakes.

Correct Answer: D. Identifying objects in a self-driving car's path

• **Computer Vision** = AI field training computers to interpret and understand the visual world through image/video analysis. • **Real-world object detection** — autonomous vehicles identify obstacles and pedestrians using visual data from cameras. • 💡 Wrong-option analysis: A (Text summarization): NLP task, processes language not images; B (Stock trends): financial analysis, requires numerical data; C (Audio translation): speech-to-text function, processes sound not visual data.

Correct Answer: A. Extremely large datasets analyzed computationally

• **Big Data** = computationally analyzed massive datasets providing information AI systems require to learn patterns effectively. • **Volume, velocity, variety** — large scale (volume), rapid generation (velocity), and diverse formats (variety) characterize big data. • 💡 Wrong-option analysis: B (Computer size): physical hardware dimension, not data characteristic; C (Software price): cost metric, irrelevant to data definition; D (Engineer count): team size, unrelated to dataset properties.

Correct Answer: C. Artificial General Intelligence

• **Artificial General Intelligence (AGI)** = theoretical AI form matching human cognitive abilities across all domains. • **Cross-domain knowledge transfer** — AGI would apply learning from one area to any other without specific retraining. • 💡 Wrong-option analysis: A (Narrow Intelligence): single-task specialization, limited scope; B (Expert Systems): rule-based decision-making, not general intelligence; D (Robotic Automation): process workflow execution, not cognitive reasoning.
