Step 1: Understanding the Concept:
The passage contrasts two theories of information:
1. Shannon-Wiener Theory: Defines information by "what it is." It's treated as a context-free, disembodied, mathematical quantity.
2. MacKay's Model: Defines information by "what it does." It's treated as a representational, verb-like process that requires context and embodiment.
Step 2: Detailed Explanation:
Let's evaluate each statement against the text:
Statement 1: The passage states that in the Shannon-Wiener theory, information is "not tied down to bodies or material instantiations." This means it is disembodied, not embodied. Therefore, Statement 1 is false.
Statement 2: The text says, "When information is made representational, as in MacKay's model, it is conceptualized as an action rather than a thing." It also links MacKay's model to defining information by "what it does." Therefore, Statement 2 is true.
Statement 3: The passage links the Shannon-Wiener definition ("what it is") directly to information becoming a "mathematical quantity." Therefore, Statement 3 is true.
Statement 4: The text explicitly says about MacKay's model that "Verb-like, it becomes a process that someone enacts." The passage starts by crediting Nicolas S. Tzannes for pointing out the distinction between the two models. Therefore, Statement 4 is true.
Step 3: Final Answer:
Statements 2, 3, and 4 are true based on the provided text.
