Let's summarize your reasoning:
Option 1: It is ruled out because it introduces the idea that only humans have the ability to think, which is not stated in the passage.
Option 3: This option is excluded as displaced reference is characterized as a feature of language, not necessarily humans.
Option 4: It is eliminated because the statement that thought precedes all speech acts is more restrictive than the passage, which mentions thought preceding all meaningful communication.
Option 2: This option is deemed the most suitable as it is concise and doesn't introduce any distortions or misrepresentations.
Your attention to the accuracy of the options in relation to the information provided in the passage is commendable. Option 2 aligns with the content of the passage and is the most appropriate choice.
