Step 1: Understanding Hockett's Design Features.
Hockett proposed several key design features that distinguish human language, including the productivity of language, displacement, and the arbitrariness of linguistic units.
Step 2: Analyzing the options.
- (1) Humans produce as many sentences as they have acquired: This is correct because humans can produce an infinite number of sentences based on the language they have learned (productivity).
- (2) Sentences cannot be broken into smaller units as they have specific meaning: This is incorrect. Sentences can be broken into smaller meaningful units (words, phrases).
- (3) Humans can talk about things that are not in their immediate vicinity: This is correct because of the feature of displacement, which allows humans to talk about things in the past, future, or abstract concepts.
- (4) Linguistic units do not bear any direct resemblance to the things they represent: This is correct because linguistic signs are arbitrary; the sound of a word does not inherently resemble the thing it refers to (arbitrariness).
Step 3: Conclusion.
The correct answers are (1), (3), and (4) as they align with Hockett's design features of language.
