Correct Answer: B. A collection of data used for training AI

• **Dataset** = organized collection of examples and information AI algorithms use to identify patterns and learn. • **Training foundation** — contains thousands of labeled instances (images, text, data points) enabling models to generalize and make accurate predictions. • 💡 Wrong-option analysis: A (Computer group): network of machines, not data collection; C (Cable set): physical network infrastructure, not information; D (Internet speed): connectivity metric, unrelated to training data.

Correct Answer: B. Privacy and data security

• **Privacy and data security** = major ethical concerns about how AI systems collect, store, and use personal information. • **Surveillance and misuse risk** — AI can enable unauthorized surveillance, facial tracking, and misinformation spreading without proper safeguards. • 💡 Wrong-option analysis: A (Faster calculations): performance improvement, not ethical issue; C (Cheaper hardware): cost reduction, not ethical concern; D (Gaming graphics): visual enhancement, unrelated to AI ethics.

Correct Answer: A. Forecasting future events based on historical data

• **Predictive analytics** = statistical and AI techniques forecasting future outcomes based on historical data patterns. • **Business decision support** — identifies fraud risks, predicts customer demand, forecasts trends enabling data-driven strategy. • 💡 Wrong-option analysis: B (Database cleaning): data preparation task, not prediction; C (Internet speed): network optimization, not forecasting; D (Logo design): graphic creation, unrelated to analytics.

Correct Answer: B. Performing a task with minimal human intervention

• **Automation** = technology-driven execution of repetitive tasks with minimal or no human intervention. • **Adaptive efficiency** — AI-driven automation adapts to changing conditions and exceptions beyond simple scripted workflows. • 💡 Wrong-option analysis: A (Buying cars): vehicle purchase, not task execution; C (Building factories): construction activity, not work automation; D (Training employees): human development, opposite of automation.

Correct Answer: B. Training

Training is the phase where an AI algorithm processes a dataset to learn patterns. During training, the model adjusts its internal parameters to minimize errors. It is the most time-consuming part of developing an AI system.

Correct Answer: B. Translating languages and understanding text

NLP is the branch of AI that deals with the interaction between computers and human languages. It powers translation apps, voice search, and automatic summarization tools. It aims to bridge the communication gap between humans and machines.
