Question restatement: The prompt presents a two-part selection task. First, determine whether 'system speed' is a functional or non-functional requirement. Second, determine whether 'payment feature' is a functional or non-functional requirement. The given answers are: ["non-functional", "functional"].

Analysis of the first dropdown (system speed):
- Option: non-functional. Rationale: System speed typically relates to quality attributes such as performance, responsiveness, latency, and throughput. These are characteristics that describe how the system operates rather than specific behaviors or functions it must perform, so they are classified as non-functional requirements. 
- Why the alternative (functional) is incorrect in this context: If we labeled system speed as functional, we would be treating speed as a specific capability or action the system must perform (e.g., the system must execute a task within a set time). However, functional requirements describe what the system should do (features and behaviors), whereas speed is about how well the system performs those functions, which is why it belongs to non-functional considerations.

Analysis of the second dropdown (payment feature):
- Option: functional. Rationale: A payment feature denotes a concrete capability that the system must provide (e.g., process payments, handle transactions, integrate with a payment gateway). Such capabilities are core functions the system must perform for users, which makes this a functional requirement. 
- Why the alternative (non-functional) is incorrect in this context: If payment were classified as non-functional, we would be describing attributes like performance, security, reliability, or usability related to payments, but not the payment function itself. The act of enabling payments is a functional capability, whereas its quality attributes would be non-functional considerations.

Summary of reasoning structure: The first item centers on whether speed is an attribute describing how well the system performs its functions (non-functional), whereas the second item concerns an actual capability the system provides (functional). The provided answers align with these distinctions: system speed as non-functional and payment feature as functional.
