Quick Questions

Shade in the A or B circle for each question.

1. Which sentence is the best one-sentence definition of AI for an exam answer?
A AI is a computer system that shows intelligent behaviour by using data and rules, reasoning and learning.
B AI is a robot that thinks and acts like a human.
2. Which answer lists the characteristics of AI correctly?
A A screen, a keyboard and a mouse.
B A collection of data and rules, the ability to reason, and the ability to learn and adapt.
3. A student writes: 'The knowledge base holds the if-then rules.' Is this correct?
A No. The rule base holds the rules. The knowledge base holds the facts and data.
B Yes. The knowledge base holds the rules.
4. Which answer describes the inference engine so that it earns the mark?
A It reasons by matching the user's answers to the rules in the rule base and the facts in the knowledge base to reach a conclusion.
B It is the screen where the user types in their answers.
5. Which answer links the interface to a reason, as a full-mark answer should?
A The interface is the part of the system that stores all the facts.
B The interface lets the user enter questions and answers, so the system can use them and then show the conclusion.

Answer Key

Writing exam answers about artificial intelligence
Section A: Quick Questions
Q1
A — AI is a computer system that shows intelligent behaviour by using data and rules, reasoning and learning.
Q2
B — A collection of data and rules, the ability to reason, and the ability to learn and adapt.
Q3
A — No. The rule base holds the rules. The knowledge base holds the facts and data.
Q4
A — It reasons by matching the user's answers to the rules in the rule base and the facts in the knowledge base to reach a conclusion.
Q5
B — The interface lets the user enter questions and answers, so the system can use them and then show the conclusion.
Section B: Match the Pairs
Q1
AI = data + rules + reasoning → A one-sentence definition: a computer system that stores data and rules and reasons to behave intelligently
Q2
ML = learn + adapt own data → Machine learning: a system that learns from experience and changes its own processes or data to improve
Q3
Name each expert system part and give its job: the knowledge base stores facts, the rule base stores IF-THEN rules → knowledge base = facts; rule base = rules
Q4
Link a point to a reason: the inference engine uses the rules to reach a conclusion, so it acts as the reasoning part → inference engine -> rules -> conclusion
Q5
AI means a robot → AI is not a robot. It is a computer system showing intelligent behaviour using data, rules and reasoning, and it may have no physical body.
Q6
Rule base = stores facts about the topic → This mixes up the two parts. The knowledge base stores the facts, while the rule base stores the rules used to reach a conclusion.
Section C: Definitions
Q1
key term + reason — Use exact key terms (data, rules, reasoning, knowledge base, rule base, inference engine, interface, machine learning) and link each point to a reason.
Section D: Fill in the Blanks
Q1
AI is a computer system that shows intelligent behaviour.
Q2
AI has data and rules, can reason, and can learn and adapt.
Q3
The knowledge base stores facts as data.
Q4
The inference engine applies rules to the facts to reach a conclusion.
Q5
Machine learning: a system adapts its own processes or data using what it learns.
Section E: Spot the Error
Q1
A — AI does not mean a robot. A full-mark definition says AI is a computer system that behaves in an intelligent way, e.g. 'AI: a computer acting smartly'.
Q2
B — The knowledge base stores the facts (data). The rules are held in the rule base, so line 2 should say 'facts'.
Q3
B — Machine learning means the program adapts its own data or processes. Following fixed steps describes a normal program, so the line should say 'program adapts its own data'.
Q4
C — Random moves are not reasoning. A full-mark answer says the program reasons to pick the best move, and links that to showing intelligence.
Q5
D — Storing facts is the job of the knowledge base. The inference engine's reason for searching and matching is to reach a conclusion.
