As a requirements engineer, you deal with a diverse range of requirements. A template for natural language functional requirements can help you to formulate different forms of system activities in a more precise way. Which two kinds of system activities are among those supported? (1 Point)

A. User interaction

B. Technical requirement

C. Quality requirements

D. Independent system activity

E. System requirement

Requirements documentation can either be natural language or model-based. Which two statements are most applicable? (2 Points)

A. If documentation is model-based, natural language documentation can be dispensed with.

B. As models are more formal, they offer a higher degree of uniqueness compared to natural language.

C. In requirements engineering models are more suitable than textual descriptions to reduce the complexity of the entity being considered.

D. When deciding between model-based and natural language documentation, model-based is preferable.

The activity diagram below shows a simplified order processing procedure. Which of the following statements is correct for this flow? (2 Points)

A. The flow is not modelled correctly, since no condition (branch)should be present within a fork.

B. The flow is modelled correctly: the goods branch as well as the export and domestic order branch are processed in parallel to one another.

C. The flow is not modelled correctly, since the branches for the domestic and export orders must be consolidated via a diamond symbol.

D. The flow is modelled correctly and the "issue invoice" activity is conducted after the "compile goods" activity.
