(Select 2) What are the characteristics of queues and backlogs?
The correct answer is A. Queues are processed in the order in which items are entered. B. Backlogs are continuously refined and can be re-prioritized. Queues follow a strict First-In, First-Out (FIFO) order - items are processed exactly as they arrive, making option A correct.

Explanation
Queues follow a strict First-In, First-Out (FIFO) order - items are processed exactly as they arrive, making option A correct. Backlogs (common in Agile/Scrum) are living lists that teams continuously groom and re-prioritize based on changing needs, making option B correct.
Why the distractors fail:
- C reverses the truth - it's backlogs, not queues, that are refined; and backlogs can be re-prioritized (the opposite of what C claims).
- D is a fabricated distinction - estimation practices vary by team and methodology; this is not a defining characteristic of either artifact.
Memory tip: Think of a queue like a grocery checkout line - you can't jump ahead. Think of a backlog like a to-do list you rewrite every week - always changing priority.
