+    * Address statuses are essential for tracking and managing addresses within the NAS.
+    * Types of address statuses include:
+      * Reserved – future use, nothing is presently there
+      * Planned – in design phase, something will be there
+      * Allocated – assigned for use, something is there
+      * Historical – no longer active, something was there
+  * **T:**  Understanding address status.
+  * **R:** Facilitates effective management, planning, and clear communication of address states.
+**Q5: Why are the concept of sub addresses important for buildings with multiple entrances and how would you navigate to an apartment in a high-rise with multiple units?**
+  * **A:**
+    * Sub addresses are used in complexes with multiple units (e.g., high-rises, multi-dwelling units).
+    * Identify each unit with a unique ID and entrance number for accessibility.
+    * Floors are categorized as basement (B), ground (G), and numbered floors (1..n).
+    * Units are numbered counterclockwise on each floor.
+    * Retain information from the old system to maintain traceability.
+  * **T:**  Understanding sub addresses
+  * **R: **Improves accessibility, accurate navigation within multi-unit buildings, and maintains traceability.

+**Q6: What defines a street and its segments in the addressing system and how does street classification impact usability in everyday situations?**
+  * **A:**
+    * A street is a grouping of one or more geometry segments that form part of a street
+    * Street segments may include cul-de-sacs and service roads.
+    * A unique identifier is given to each street and links street segments to streets.
+    * Street classification determines the type and function of a street.
+    * Street segments include geometries based on various mapping data; ensuring accuracy is crucial.
+    * The directional attribute indicates if a street segment is one-way for proper navigation.
+  * **T:**  Understanding the data model of streets.
+  * **R: **Ensures accurate routing, improved urban planning, and enhances navigation efficiency.
+**Q7: How do area and destination data improve way-finding navigation in urban areas and why is it important to establish relationships between destinations and address units?**
+  * **A:**
+    * Destination Table: Contains point representations and where available polygons that delineate areas.
+    * Destinations and areas are essential for directional signage, e.g. Madinat Sultan Qaboos
+    * Key Attributes: Unique IDs, names (in Arabic and Romanized), and hierarchy levels are crucial for signage.
+    * Importance: Supports effective way-finding, helping residents and visitors easily locate places.
+    * Hierarchy Relations: Establishing relationships between destinations and address units ensures consistency and clarity.
+  * **T:**  How areas and destinations fit into the data model.
+  * **R: **Supports effective wayfinding, clarity, and consistency for navigation and urban signage.
+**Q8: What are the different classes of streets and why is it important to classify them and how does street classification impact daily travel and navigation for residents?**
+  * **A:**
+    * Streets are classified into National, Arterial, Secondary, Distributor, Access and Track categories.
+    * Access is further divided into vehicular and pedestrian types
+    * Each street receives one classification for improved navigation and urban planning.
+    * Using standardized classifications helps in determining what street signs to put where, dimensioning, frequency etc.
+  * **T:**  Understanding street classification.
+  * **R: **Improves navigation, efficient urban management, and clear traffic guidance.
+**Q9:** **What are the different statuses a street can have, and why is it important to know them?**
+  * **A:**
+    * Temporary: Not permanent and subject to change.
+    * Planned: Under design, not yet built.
+    * Current: Existing and available for use.
+    * Historical: No longer in regular use, but still recognized, e.g. for older records/data.
+  * **T:**  Understanding street status.
+  * **R: **Essential for urban planning, road maintenance, and informing residents clearly.
+**Q10: Why is it important to classify data quality for addressing and how does knowing the method of data collection affect how they can be used?**
+  * **A:**
+    * Data quality is essential for reliable addressing and accurate mapping.
