Question

How does the formality gap impact the validation of interactive systems?

a.

It makes validation proofs more objective and precise.

b.

It allows for mathematical proofs to be applied directly to interactive requirements.

c.

It creates a disparity between informal real-world situations and formal design processes.

d.

It ensures that validation can be completely automated without subjective input.

Answer: (c).It creates a disparity between informal real-world situations and formal design processes. Explanation:The formality gap creates a disparity between informal real-world situations, which are often the origin of customer requirements, and the formal design processes used in software development. This disparity makes validation of interactive systems more challenging, as it requires subjective proof and interpretation to bridge the gap between informal requirements and formal design activities.
