Question

At what levels of abstraction can the PIE model be applied?

a.

Only at the physical/lexical level of interpretation

b.

Only at the logical level of interpretation

c.

At multiple levels of abstraction

d.

Only at the user's intended action level

Answer: (c).At multiple levels of abstraction Explanation:The PIE model can be applied at multiple levels of abstraction, including the physical/lexical level (raw physical inputs and outputs), logical level (higher-level actions and interface elements), and even within the user (user's intended actions and perceived response). Different levels can be mapped between, leading to level conformance properties.
