Answer:
(C) encode not only the timeframe of an event but also the origin of the speaker's knowledge, whether direct observation, hearsay, or intuition; as a result, speakers of those languages cannot state facts without attributing them to a source
Step-by-step explanation:
Proofreading the sentence, the correct sentence is ".... encode not only the timeframe of an event but also the origin of the speaker's knowledge, whether direct observations, hearsay, or intuition; as a result, speakers of those languages cannot state facts without attributing them to a source.
"
The word "but" is used as a conjunction in the above proofreading to connect the clause "verb encode not only the timeframe of an event" to another clause " also the origin of the speaker's knowledge, whether direct observation, hearsay, or intuition,".
There is a sharp contrast between the two clauses marked with the conjunction "but" is the correct option from the group of answer choices.
Also, use of the word "whether" after " the speaker's knowledge" In the sentence gives more information about the origin of the speaker's knowledge, if the origin of such knowledge is either from a direct observation, hearsay, or an intuition.
The use of the semicolon, use to link the conjunctive adverbial phrase " As a result" indicate a cause-and-effect relationship between the first sentence that explains the uses of verb as both "encoding the timeframe of an event" and also "stating the origin of the speaker's knowledge whether through direct observation, hearsay, or intuition." to the effects which is why " speakers of those languages cannot state facts without attributing them to a source."
