Verified Answers | Complete Q&A Guide | A+ Graded
1. Which of the following best defines an agent as described in Artificial Intelligence: A Modern
Approach?
A. A computer program that can solve any problem
B. An entity that takes action in response to percepts from an environment
C. A system that can only perform logical reasoning
D. A machine that mimics human emotions
Answer: B – An agent is defined as an entity that takes action in response to percepts from an
environment.
2. According to the AIMA textbook, artificial intelligence is best defined as:
A. The study of machines that can think like humans
B. The study and construction of agent programs that perform well in a given class of environments
C. The development of robots that can replace humans
D. The creation of programs that can pass the Turing Test
Answer: B – Artificial intelligence is defined as the study and construction of agent programs that
perform well in a given class of environments, for a given agent architecture.
3. Rationality in an AI system refers to:
A. The ability to make decisions based on emotions
B. The property of a system which does the "right thing" given what it knows
,C. The ability to solve any problem perfectly
D. The capacity to learn from experience
Answer: B – Rationality is defined as the property of a system which does the "right thing" given what it
knows.
4. Logical reasoning is best described as:
A. The process of making decisions based on intuition
B. The process of deriving new sentences from old, such that the new sentences are necessarily true if
the old ones are true
C. The ability to solve problems using trial and error
D. The process of learning from examples
Answer: B – Logical reasoning is the process of deriving new sentences from old, such that the new
sentences are necessarily true if the old ones are true.
5. In the context of AI, a "percept" is:
A. A conclusion drawn by the agent
B. The sensory input received by an agent from its environment
C. A decision made by the agent
D. An action taken by the agent
Answer: B – A percept is the sensory input an agent receives from its environment, which forms the
basis for its actions.
,6. Which of the following is NOT a standard approach to defining AI mentioned in the textbook?
A. Systems that think like humans
B. Systems that act like humans
C. Systems that think rationally
D. Systems that act emotionally
Answer: D – The four standard approaches are: thinking humanly, acting humanly, thinking rationally,
and acting rationally. Acting emotionally is not a standard approach.
7. The Turing Test is designed to test:
A. A machine's ability to solve complex mathematical problems
B. A machine's ability to exhibit intelligent behavior equivalent to a human
C. A machine's processing speed
D. A machine's ability to learn from data
Answer: B – The Turing Test tests whether a machine can exhibit intelligent behavior equivalent to, or
indistinguishable from, that of a human.
8. Which objection to the Turing Test remains relevant today?
A. Machines cannot think because they lack consciousness
B. Machines cannot pass the test because they are too slow
C. Machines cannot understand natural language
D. Machines cannot learn from experience
, Answer: A – The objection that machines cannot truly "think" because they lack consciousness or
understanding remains a philosophical challenge to the Turing Test.
9. A model of cognitive activity that involves complex mathematical operations such as convolution
suggests that:
A. Humans consciously perform these calculations
B. The visual system may perform such computations without the person's awareness
C. Such models are unrealistic
D. Only computers can perform these operations
Answer: B – Such models suggest that the visual system may perform complex computations without
the person being consciously aware of them.
10. The "brain" of an advanced educational assistant typically consists of:
A. A single algorithm
B. Multiple components working together
C. A simple rulebased system
D. A human operator
Answer: B – Advanced educational assistants consist of multiple components that form the foundation
for intelligent tutoring systems.
11. Which of the following is a key characteristic of intelligent agents?
A. They always produce perfect solutions
