AI agent, Nature of Environment

What is the main goal of Artificial Intelligence?

• To create expert systems
• To solve puzzles
• To understand emotions
• To make machines intelligent

Answer explanation

AI aims to develop systems that exhibit intelligent behavior and act autonomously.

Which of the following best defines an intelligent agent?

• An entity that can play chess
• A robot that follows instructions
• An entity that perceives its environment and acts upon it
• A program that stores data

Answer explanation

An intelligent agent perceives and acts to maximize its success.

Which of the following is NOT a component of the agent function?

• Perception
• Action
• Environment
• Thinking

Answer explanation

The environment is external to the agent, not part of its internal function.

Which type of environment provides complete information at all times?

• Fully observable
• Partially observable
• Stochastic
• Dynamic

Answer explanation

Fully observable environments allow the agent full access to the state of the world.

What makes an agent rational?

• Its ability to learn from data
• Following random actions
• Maximizing performance measure
• Being programmed by a human

Answer explanation

A rational agent acts to achieve the best expected outcome based on its knowledge.

In a stochastic environment:

• The outcome is always known
• Outcomes are uncertain
• Agents are not allowed
• Sensors do not work

Answer explanation

A stochastic environment has randomness and unpredictability.

Which agent type maintains an internal model of the world?

• Simple reflex agent
• Model-based reflex agent
• Goal-based agent
• Utility-based agent

Answer explanation

Model-based agents use internal models to handle partial observability.

Which of the following best describes a utility-based agent?

• It ignores performance
• It only reacts to current input
• It chooses actions based on utility values
• It stores all past data

Answer explanation

A utility-based agent evaluates multiple possibilities and chooses the most useful one.

What is a percept in the context of intelligent agents?

• The physical body of an agent
• A command given to an agent
• A signal received from the environment
• A built-in goal of the agent

Answer explanation

A percept is what an agent receives from the environment through its sensors.

Which of the following environments is most difficult for an agent?

• Fully observable and deterministic
• Static and discrete
• Partially observable and stochastic
• Single-agent and episodic

Answer explanation

Partially observable and stochastic environments are hard due to uncertainty and limited information.
