Introduction to AI

Correct answer: A. False

The statement is false because AI can automate some tasks and assist people, but it does not replace humans in every task or situation. Human judgment, empathy, responsibility, values, and social understanding remain important in many contexts. The absolute words “always” and “completely” make the claim especially inaccurate.

Correct answer: A. Artificial Intelligence can learn from data

Many AI systems can learn patterns from data or examples and use them to produce predictions or decisions, whereas ordinary rule-based programs generally follow instructions explicitly written by programmers. This is a useful introductory distinction, although real systems can combine both approaches. AI still needs computing resources and electricity.

Correct answer: D. It can produce incorrect or unfair results because of incorrect or biased data.

AI learns from data and follows the objectives, instructions, and design provided by people. If the training data are inaccurate, incomplete, or biased, the system may reproduce those problems in its outputs. AI can also fail on situations unlike its training examples. Therefore it is not guaranteed to be always correct, fair, or better than human judgment, and human review remains important.

Correct answer: A. Useful information that helps identification

In AI and machine learning, a feature is a measurable property or piece of information used to describe an example and help distinguish it from others. A useful feature has a meaningful relationship with the task, such as shape or colour when identifying an object. Unrelated information, deleting data, or the machine’s appearance does not by itself help the system identify the target.

Correct answer: C. सीखे हुए पैटर्न के आधार पर नए इनपुट के परिणाम का अनुमान लगाना

During training, an AI model learns relationships or patterns from examples. Afterward, it can apply those learned patterns to new inputs and estimate a category or likely outcome. This is generalisation, not simple memorisation. However, performance depends on the quality and relevance of training data, so training does not guarantee perfect decisions in every unfamiliar situation.

Correct answer: A. Ability to learn from data

Learning from data means identifying useful patterns in examples or experience and using them to improve future predictions or decisions. This is associated with machine-learning approaches. A system that only follows fixed instructions may perform consistently, but it does not necessarily improve from experience. No system is guaranteed to be correct without suitable information.

Correct answer: B. It can give wrong outputs from wrong data

AI systems depend on the quality and suitability of their data, instructions, and design. If the input data are inaccurate, incomplete, or biased, the system may learn misleading patterns and produce unreliable outputs. This is a practical limitation. The other options make absolute claims that ignore the need for data, testing, and human checking.

Correct answer: D. Wrong idea

This is a wrong idea because AI may automate particular tasks or assist people, but it does not automatically replace humans in every field or situation. Human judgement, accountability, empathy, values, and contextual understanding remain important. The words “everywhere” and “completely” make the claim too absolute; the more accurate view is that humans and AI may work together.

Correct answer: A. It is a technology that helps machines recognise patterns, learn, and support decision-making using data, rules, or experience.

AI refers broadly to techniques that enable computer systems to perform tasks associated with human intelligence, such as recognising patterns, learning from examples, understanding inputs, predicting, or supporting decisions. These systems require data, rules, instructions, or training and can make errors. AI is not limited to robot appearance and does not remove human responsibility in every situation.
