Q101.
How are concurrent dialog elements typically represented using production rule systems?

a.

By using a linear sequence of rules

b.

By allowing only one rule to fire at a time

c.

By keeping track of the current state using attributes or events

d.

By introducing variables to describe numeric values

Discuss
Answer: (c).By keeping track of the current state using attributes or events Explanation:Concurrent dialog elements are typically represented in production rule systems by keeping track of the current state using attributes or events, allowing multiple rules to be active at the same time.
Q102.
How does the number of rules required for toggles in a mixed event/state production system scale with the number of toggles?

a.

It increases quadratically.

b.

It remains constant.

c.

It decreases linearly.

d.

It increases linearly.

Discuss
Answer: (d).It increases linearly. Explanation:In a mixed event/state production system, the number of rules required for toggles increases linearly with the number of toggles.
Q103.
How can the concept of "escape" be implemented using production rules?

a.

By using a special event named "escape"

b.

By setting all state attributes to some standard value

c.

By allowing any rule to be reset

d.

By firing all rules at once

Discuss
Answer: (b).By setting all state attributes to some standard value Explanation:The concept of "escape" can be implemented using production rules by having a rule that involves setting all state attributes to some standard value when the "escape" event occurs.
Q104.
What limitation do production rules have when it comes to sequential dialogs?

a.

They cannot handle concurrency.

b.

They cannot represent attributes.

c.

They struggle to analyze numeric values.

d.

They require keeping track of the current sequence state.

Discuss
Answer: (d).They require keeping track of the current sequence state. Explanation:In sequential dialogs, production rules require keeping track of the current sequence state, which can be awkward to code and analyze.
Q105.
What is a potential advantage of using different precedence rules for firing production rules?

a.

It simplifies the rule descriptions.

b.

It ensures every rule is executed.

c.

It allows for pre-emptive dialog boxes.

d.

It increases the total number of rules.

Discuss
Answer: (c).It allows for pre-emptive dialog boxes. Explanation:Using different precedence rules for firing production rules allows for pre-emptive dialog boxes to be programmed, giving higher priority to certain rules over others.
Q106.
How does a mixed event/state production system overcome the limitations of sequential dialogs?

a.

By adding more attributes to the system's memory

b.

By relying solely on state attributes

c.

By using a complex syntax for rule descriptions

d.

By combining the strengths of event and state representations

Discuss
Answer: (d).By combining the strengths of event and state representations Explanation:A mixed event/state production system overcomes the limitations of sequential dialogs by combining the strengths of both event and state representations, allowing for more flexibility in describing complex sequences.
Q107.
In the context of rule precedence, how might cursor movement events in a word processor be handled?

a.

They will trigger the normal system rules.

b.

They will be ignored.

c.

They will trigger the help system rules.

d.

They will be processed concurrently.

Discuss
Answer: (c).They will trigger the help system rules. Explanation:Cursor movement events in a word processor might be handled by triggering the help system rules due to different precedence rules.
Q108.
What is a key advantage of a mixed event/state production system over STNs for handling concurrency and sequence?

a.

Reduced memory usage

b.

Simplicity in rule descriptions

c.

Lower processing time

d.

Linear increase in the number of rules

Discuss
Answer: (d).Linear increase in the number of rules Explanation:A key advantage of a mixed event/state production system over STNs is the linear increase in the number of rules when handling both concurrency and sequence, as opposed to exponential growth in STN states.
Q109.
Why is CSP (Communicating Sequential Processes) chosen as a notation for dialog specification?

a.

It is solely designed for sequential dialogs.

b.

It offers concise notation for single-choice scenarios.

c.

It excels in handling both sequential and concurrent behavior.

d.

It simplifies the handling of numeric values.

Discuss
Answer: (c).It excels in handling both sequential and concurrent behavior. Explanation:CSP is chosen as a notation for dialog specification because it is capable of specifying both concurrency and sequence effectively, making it suitable for dialog descriptions with complex behavior.
Q110.
In CSP notation, what does the symbol '→' represent?

a.

Choice between events

b.

Synchronization between processes

c.

Sequence of events

d.

Parallel composition of processes

Discuss
Answer: (c).Sequence of events Explanation:In CSP notation, the symbol '→' represents the sequence of events, indicating the order in which events are executed within a process.
