Introduction to AI

Correct answer: A. The ability of machines to perform tasks that normally require human intelligence

Artificial Intelligence refers to systems that perform tasks associated with human intelligence, such as recognising patterns, understanding language, learning from examples, or making decisions. Creating digital images may be one AI application, but it is not the whole field. Internet speed and shutting down a computer are unrelated definitions.

Correct answer: A. Identifying the problem

An AI project should begin with a clear problem or goal: what needs to be improved, predicted, classified, or automated? Once the problem is defined, suitable data and a possible solution can be considered. Buying expensive equipment, deleting files, or answering without thought does not define the purpose of an AI system.

Correct answer: A. Solving problems intelligently

A main goal of AI is to enable systems to perform tasks associated with intelligent behaviour, including recognising patterns, reasoning, predicting, learning, and solving problems. The other options describe arbitrary physical or economic changes and have no general connection with AI’s purpose. AI may be used in many applications, but intelligent problem-solving is central.

Correct answer: A. A system that analyses medical images to identify possible signs of disease

A medical-image system can analyse pixels and visual patterns to identify signs that may be associated with a disease. This is an AI application because the system processes data and produces an inference. An empty box, closed book, or simple spoon does not independently analyse information or make such predictions.

Correct answer: A. To understand new problems, ask questions, and find solutions

Curiosity encourages a learner to ask how and why a system works, investigate unfamiliar problems, test ideas, and learn from mistakes. These habits build genuine understanding and support creative problem-solving in AI. Memorising without understanding, avoiding experiments, or using only one method restricts learning rather than strengthening it.

Correct answer: A. Voice assistant on a phone

A phone voice assistant processes spoken language, identifies the user’s request, and generates a response or performs an action. This involves AI capabilities such as speech recognition and language understanding. A basic calculator follows fixed arithmetic operations, while a notebook and mechanical alarm do not analyse language or adapt responses.

Correct answer: A. When it saves time and gives useful suggestions

AI is helpful when it supports a meaningful task, reduces repetitive effort, saves time, or provides relevant suggestions that a person can review and use. It is not helpful merely because it is automated. Spreading unverified information, causing harm, or stopping without reason reduces usefulness and may create risk.

Correct answer: A. Automatically classifying emails by subject

An AI email classifier can examine subject lines or message content, recognise patterns, and place messages into useful categories automatically. This reduces repetitive manual work and saves time. Manual classification is slower, while deleting messages without reading them is unsafe and stopping a clock does not actually reduce the time spent.

Correct answer: A. It is a misconception.

The statement is a misconception because AI is a method of processing information, learning patterns, or producing intelligent outputs, and it can exist with or without a physical robot. Voice assistants, recommendation systems, translation tools, and medical-image systems are examples of non-robotic AI applications. Hence A is correct.

Correct answer: B. Identifying similar types of objects in images

In pattern recognition, AI identifies recurring features, shapes, or regularities in data. Recognising similar kinds of objects, such as cats, cars, or trees, across different images is therefore an example of pattern recognition, making option B correct. In contrast, arranging files alphabetically follows a predefined rule. Moving an object with a robotic arm is a control or movement task, while finding the shortest route is mainly a path-planning problem. These tasks may use AI, but they are not the direct example of recognising patterns in visual data asked here.

Correct answer: B. Video recommendation system

A video recommendation system analyses information such as viewing history, searches, and preferences to identify patterns and suggest content likely to interest a user. This is a common daily-life AI application. Folding clothes, tearing paper, and painting a door are ordinary manual actions and do not require a system to learn patterns or make recommendations.

Correct answer: B. It can help machines learn patterns from data and make decisions.

AI systems can process data, learn or identify patterns, and use those patterns to classify, predict, or support decisions. Thus option B is correct. AI is not guaranteed to be correct every time, so option A is false; it is used in many fields beyond toys, and data is central to most modern AI systems.

Correct answer: A. Artificial Intelligence assists with a task, and a human checks the results.

AI can analyse data, suggest actions, or perform repetitive work, but it may also contain errors, bias, or incomplete information. Human beings should therefore review important outputs and take responsibility for decisions. Option A shows this balanced partnership; B and C remove necessary human oversight, while D wrongly limits AI to games.

Correct answer: B. False

The statement is false because AI can exist in software and services that have no physical robot body. Examples include voice assistants, spam filters, recommendation systems, image tools, and some medical-support applications. Option B is correct. Option C is not suitable because the original claim says AI is limited only to robots, which is clearly incorrect rather than partly correct.

Correct answer: B. Automatically sorting information

AI can learn or use patterns to classify and organise large amounts of information automatically. This reduces repetitive manual work and allows a person to spend time on more useful tasks. Option B shows this time-saving function. Manual sorting in A generally takes longer, while stopping work or losing information does not improve efficiency or provide a useful AI service.

Correct answer: B. Learning from data to identify an email as spam or normal

A spam filter can learn patterns from previous messages and use features such as words, sender information, and links to classify a new email. This learning-based classification is an AI example, so B is correct. A calculator follows fixed arithmetic rules, while reading paper or pressing a switch manually does not involve an AI system.

Correct answer: A. It is a useful technology, but responsible use is necessary.

AI can improve efficiency and support work in education, health, communication, and many other areas, but it is not infallible or suitable for every decision. Errors, bias, misuse, and privacy risks must be considered, and appropriate human oversight should remain. Option A gives this balanced view; the other choices make absolute and inaccurate claims.

Correct answer: A. The problem to be solved and its purpose

An AI project should begin by defining the problem, the users affected, and the result the system is expected to produce. This goal guides decisions about data, methods, evaluation, and responsible use. The colour of a computer, office decoration, and number of chairs do not define the task or tell developers whether the system is useful.

Correct answer: B. AI is a technology that helps machines learn, recognise patterns, or make decisions using data.

Artificial Intelligence refers broadly to methods that enable computer systems to perform tasks such as recognising patterns, understanding language, making predictions, or supporting decisions. It is used in many software systems and devices, not only robots or internet searches. AI depends on data, instructions, and design choices, so it can make mistakes and does not always produce a correct answer independently.

Correct answer: A. By providing crop and weather-related advice

Artificial Intelligence can analyse weather records, soil conditions, crop growth, and past farm data to provide useful advice about sowing, irrigation, fertiliser use, and possible pest attacks. Therefore, option A is correct. The other choices describe unsafe or unhelpful practices that ignore evidence and differences between fields.

Correct answer: B. ईमेल को स्वचालित रूप से स्पैम, प्राथमिक और सामान्य श्रेणियों में बाँटना

Automatically sorting emails into spam, priority, and general folders is an example of AI-assisted time saving. An AI system can examine patterns such as words, senders, and previous choices, then place messages in suitable categories. This reduces repeated manual work while still allowing the user to review important messages. Reading every email by hand takes more time, deleting all messages is unsafe, and taking no action is not automation.

Correct answer: A. संगीत ऐप का सुनने के इतिहास के आधार पर नए गीत सुझाना

A music application that recommends songs from a person’s listening history is using an AI-based recommendation process. It can identify patterns in earlier choices and predict what the listener may enjoy, although such predictions are not always perfect. A printed calendar, a wall clock, and a handwritten shopping list provide fixed information or record information; they do not analyse behaviour to generate personalised suggestions. Thus, option A is correct.

Correct answer: B. यह उपयोगी है, पर इसके जिम्मेदार उपयोग की आवश्यकता है

A balanced view recognises both the usefulness and the limitations of AI. AI can help with tasks such as translation, recommendations, and data analysis, but its output may contain errors or reflect unfair patterns in the data used to develop it. People should therefore protect privacy, consider fairness and safety, and check important results. Saying that AI is always wrong, only for entertainment, or safe to trust without checking is not balanced.

Correct answer: D. दोहराए जाने वाले कार्यों में समय बचाना

Automation allows software or machines to perform defined steps with little repeated human intervention. In AI-supported work, this can save time on routine activities such as sorting records, entering predictable data, or preparing a first draft of a report. Automation does not guarantee perfect quality, and it should not be used to hide mistakes; outputs still need suitable supervision. Thus, saving time in repetitive tasks is the valid benefit in option D.

Correct answer: B. Verifying a person's identity before granting entry by using facial recognition

A facial-recognition system can compare facial features with authorised records and support identity checks before access is granted. Thus, option B is an example of AI-assisted security. It should still be used lawfully and with privacy safeguards. Unchecked entry, public data sharing, or ignoring failed verification increases risk.
