D. To connect computers so they can exchange information efficiently

Answer: (C)

Explanation

Artificial intelligence seeks to create systems that perform tasks usually associated with human intelligence and simulate aspects of human thinking. Faster hardware and networking support computing but do not define AI's central aim.

2. How does most current narrow AI differ from general human intelligence?

A. It develops flexible abilities across the full range of human activities

B. It relies on human operators to perform every classification decision

C. It is designed for one task or a limited group of tasks

D. It focuses on storing information rather than interpreting or producing results

Answer: (C)

Explanation

Most current AI systems have a narrow scope and are built for defined tasks or limited task groups. Human intelligence is broader and is not confined to a single specialized function.

3. Which statement correctly describes the relationship among artificial intelligence, machine learning, deep learning, and generative AI?

A. Generative AI contains AI, AI contains machine learning, and deep learning operates outside machine learning

B. Deep learning contains AI, machine learning contains generative AI, and AI excludes rule-based approaches

C. AI contains machine learning, machine learning contains deep learning, and generative AI commonly uses deep learning

D. Machine learning contains AI, AI contains deep learning, and generative AI replaces machine learning

Answer: (C)

Explanation

Artificial intelligence is the broad field, machine learning is one part of it, deep learning is a specialized machine-learning approach, and generative AI commonly uses deep-learning models. The other choices reverse or misplace these levels in the hierarchy.

4. What distinguishes machine learning from traditional programming?

A. Machine learning follows a complete set of fixed rules written for every situation

B. Machine learning produces results by storing identical copies of every earlier case

C. Machine learning discovers patterns from data to support predictions or judgments

D. Machine learning performs calculations without using examples from previous cases

Answer: (C)

Explanation

Machine learning identifies patterns in data and uses them to make predictions or judgments. Traditional programming generally applies explicitly specified rules, while storing copies of past cases is not the defining learning process.

5. What is a defining characteristic of deep learning?

A. It applies a short list of manually written rules to a narrowly defined problem

B. It classifies data through fixed calculations that do not adjust from examples

C. It uses neural networks to learn complex patterns, often from substantial data

D. It generates new content without relying on a machine-learning method

Answer: (C)

Explanation

Deep learning is an advanced machine-learning approach that uses neural networks to learn complex patterns and generally benefits from relatively large amounts of data. It is not defined by fixed rules or by operating independently of machine learning.

6. What does generative AI primarily do?

A. It measures hardware performance by comparing computational speeds

B. It applies explicit programming rules to retrieve a stored document unchanged

C. It sorts existing information into categories without producing additional content

D. It uses deep learning to create new text, images, audio, or other data

Answer: (D)

Explanation

Generative AI uses deep-learning models to generate new content and data, including text, images, and audio. Categorizing existing information describes an analytical task rather than the defining function of generative AI.

7. How does a machine-learning system typically classify a new case?

A. It manually inspects every earlier example and finds an identical stored case

B. It learns recurring patterns from many previous examples and applies them to the new case

C. It waits for a person to label the new case after reviewing the system's output

D. It assigns a category by following a fixed rule unrelated to previous data

Answer: (B)

Explanation

A machine-learning system studies many examples, detects recurring patterns, and uses those patterns to predict the category or outcome of a new case. It does not need to locate an identical prior case or depend on a person for every classification.

8. How does a spam filter use machine learning to handle a new email?

A. It creates a new message and labels it according to the content it generated

B. It learns patterns from earlier messages and predicts whether the new message is spam

C. It compares the message with purchasing histories and predicts a product preference

D. It applies one fixed calculation to the message without learning from examples

Answer: (B)

Explanation

A spam filter learns recurring patterns from previous email messages and uses them to predict whether a new message is spam. Product-preference prediction belongs to recommendation systems, while fixed calculation and content generation describe different processes.

9. What best defines an artificial neural network?

A. A calculator that produces results through explicitly entered arithmetic steps

B. A computational model that uses connected layers to transform inputs into outputs

C. A storage system that records examples without processing their relationships

D. A fixed procedure that applies a manually written rule to every input

Answer: (B)

Explanation

An artificial neural network is modeled in a simplified way on connections between neurons and processes information through connected layers. A fixed rule does not learn patterns from examples, so it does not capture the defining feature of a neural network.

10. How does a neural network typically recognize an object in an image?

A. It converts the image into text and applies a translation procedure

B. It compares the entire image with one manually written rule

C. It selects a category before examining lines, colors, or shapes

D. It processes visual features through layers before producing a recognition decision

Answer: (D)

Explanation

In visual recognition, the network analyzes features such as lines, colors, and shapes through connected layers before reaching a final decision. Treating the whole image with one manually written rule confuses layered learning with fixed programming.

11. What is the main distinction between a classification system and a generative system?

A. Classification requires images, whereas generation works with text and sound

B. Classification selects a predefined category, whereas generation creates new content

C. Classification analyzes neural layers, whereas generation performs fixed arithmetic

D. Classification creates original content, whereas generation selects a predefined category

Answer: (B)

Explanation

A classification system chooses among established options such as spam or not spam, while a generative system produces new content in response to a prompt. The reversed distinction incorrectly assigns content creation to classification.

12. What sequence describes a typical generative AI interaction?

A. A system copies an existing item before adjusting it to fit the prompt

B. A user selects a category, and a fixed rule retrieves the matching item

C. A model produces content first, then a user writes a prompt to label it

D. A user gives a prompt, a trained model processes it, and content is produced

Answer: (D)

Explanation

Generative AI begins with a user prompt, applies a trained model, and produces content such as text, images, or audio. The output is generated in response to the prompt rather than necessarily being a copied existing item.

13. Which task is presented as requiring artificial intelligence rather than being a simple fixed computation?

A. Displaying the time remaining on a timer

B. Calculating a total from entered numbers

C. Recognizing objects in an image

D. Applying a fixed arithmetic formula

Answer: (C)

Explanation

Image recognition is an example of a task that can require artificial intelligence because it involves interpreting patterns. A remaining-time display and a simple calculator are presented as straightforward computational tasks.

14. Which pairing correctly matches each application area with its primary function?

A. Machine learning processes images manually, deep learning translates words, and generative AI selects fixed categories

B. Machine learning predicts from learned patterns, deep learning processes complex neural networks, and generative AI creates new content

C. Machine learning stores examples, deep learning displays results, and generative AI performs ordinary calculations

D. Machine learning creates new content, deep learning predicts from simple rules, and generative AI processes arithmetic

Answer: (B)

Explanation

Machine learning centers on learning patterns for prediction, deep learning uses complex neural-network processing, and generative AI focuses on creating new content. The other pairings assign functions that do not match these primary classifications.

15. What best defines an AI hallucination?

A. A creative response that clearly identifies which details are hypothetical

B. A brief response that omits background information but remains accurate

C. A convincing response that is invented or unsupported by reliable evidence

D. A current response that summarizes information from several verified sources

Answer: (C)

Explanation

An AI hallucination can sound persuasive while being invented, incorrect, or unsupported by dependable evidence. A polished or convincing presentation does not establish that the information is true.

16. How should an AI system’s role be understood when making an important decision?

A. As a research partner whose suggestions can replace expert judgment

B. As a knowledge source whose conclusions need no further examination

C. As a reference tool whose answers are reliable when phrased confidently

D. As a powerful assistant whose output requires human review

Answer: (D)

Explanation

AI can provide useful assistance, but human review is needed before treating its output as dependable. Confidence or sophisticated wording does not make an AI response a final source of truth.

17. Which procedure provides the strongest verification of an AI-generated claim?

A. Compare the claim with a familiar example and submit it if no contradiction is noticed

B. Check the original source, compare reliable references, assess its logic, and take responsibility for using it

C. Accept the claim when its wording sounds professional and its explanation appears complete

D. Ask the same AI system to rewrite the claim more clearly before using it

Answer: (B)

Explanation

Responsible verification combines source checking, comparison with trustworthy references, logical evaluation, and personal accountability for the submitted information. Professional wording or a clearer rewrite does not demonstrate that a claim is accurate.

18. What is the most appropriate way to use generative AI when learning or writing code?

A. Use it to replace drafting and analysis whenever the requested task appears familiar

B. Use it to support understanding while checking every line and retaining personal judgment

C. Use it to suggest ideas, then accept its explanations when they seem technically plausible

D. Use it to produce a complete solution so that independent reasoning can be minimized

Answer: (B)

Explanation

Generative AI is intended to aid understanding and thinking, with its output checked carefully rather than treated as a substitute for reasoning or coding. Plausible technical language can still contain mistakes that require human judgment.

19. Which statement best captures the main benefit and main risks of generative AI?

A. It speeds up large-scale content production and routine work, but may introduce false information and weaken critical thinking

B. It improves factual accuracy through rapid drafting, but may make ordinary tasks take longer to complete

C. It produces imaginative content efficiently, but its principal risk is that users receive too little information

D. It replaces creative planning with dependable answers, but mainly creates risks when access to data is limited

Answer: (A)

Explanation

Generative AI can save time by producing substantial content, handling routine tasks, and supporting brainstorming, while risks include hallucinations, confusion between fact and imagination, and overreliance. The central concern is not slower work or insufficient information, but reduced reliability and critical judgment.
