Q81.
What advantage is associated with using existing tools for executing BNF and regular expressions?

a.

Simplified syntax for regular expressions

b.

Inclusion of concurrent dialogs

c.

Availability of prototyping tools

d.

Exclusive use on PCs

Discuss
Answer: (c).Availability of prototyping tools Explanation:Existing tools for executing BNF and regular expressions are advantageous because they are readily available and can be used to build prototyping tools.
Q82.
What level of dialog is often the focus when using regular expressions as a notation?

a.

High-level description

b.

Complex recursive elements

c.

Concurrency handling

d.

Parsing single lines of textual input

Discuss
Answer: (d).Parsing single lines of textual input Explanation:When using regular expressions as a dialog notation, they are typically confined to parsing single lines of textual input or describing individual interface widgets.
Q83.
What type of dialog element is NOT handled well by regular expressions and BNF?

a.

Low-level description

b.

Iteration

c.

Bracket matching

d.

Named subexpressions

Discuss
Answer: (c).Bracket matching Explanation:Regular expressions and BNF struggle to handle bracket matching.
Q84.
What is the key consideration for determining whether to use BNF, regular expressions, or other notations for dialog representation?

a.

Availability of existing tools

b.

Complexity of user interactions

c.

Availability of named subexpressions

d.

Need for iteration in dialogs

Discuss
Answer: (b).Complexity of user interactions Explanation:The choice between BNF, regular expressions, and other notations depends on whether the dialogs involve complex recursive elements like bracket matching.
Q85.
What is the general form of production rules?

a.

If action then condition

b.

Condition → action

c.

Action: condition

d.

Action → condition

Discuss
Answer: (b).Condition → action Explanation:The general form of production rules is "condition → action".
Q86.
What happens when the conditions of a production rule become true?

a.

The rule becomes inactive.

b.

The rule is skipped.

c.

The rule is said to fire and the action is executed.

d.

The system enters a waiting state.

Discuss
Answer: (c).The rule is said to fire and the action is executed. Explanation:When the conditions of a production rule become true, the rule is said to fire, and the action specified in the rule is executed.
Q87.
In production rule systems, what does the term "event-oriented" refer to?

a.

The rules are ordered by events.

b.

The rules are based on user-initiated events.

c.

The rules are only focused on internal events.

d.

The rules are executed in a sequential order.

Discuss
Answer: (b).The rules are based on user-initiated events. Explanation:In an event-oriented production rule system, the rules are based on user-initiated events and their conditions are matched against the user's actions.
Q88.
What type of events are represented in angle brackets in production rule systems?

a.

User events

b.

Internal events

c.

System response events

d.

Conditional events

Discuss
Answer: (c).System response events Explanation:System response events, such as <draw line>, are represented in angle brackets in production rule systems. These events are the visible or audible effects of the system.
Q89.
What is the role of the dialog manager in a production rule system?

a.

To execute user actions

b.

To mediate interaction with the user

c.

To manage system response events

d.

To maintain the system's memory

Discuss
Answer: (b).To mediate interaction with the user Explanation:The role of the dialog manager in a production rule system is to mediate interaction with the user. It manages the event memory, where user events are added and system response events are removed.
Q90.
What happens to the events named in the condition when a rule fires?

a.

They are added to the memory.

b.

They are removed from the memory.

c.

They are skipped.

d.

They trigger system responses.

Discuss
Answer: (b).They are removed from the memory. Explanation:When a rule fires, the events named in the condition are removed from the system's memory.
