Select the most appropriate option to fill in blank no. 2.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. were.
Context: The sentence is: “Chatbots are computer programs (1) ______ to simulate conversations as if they (2) ______ another human.”
The phrase “as if” is usually followed by the past subjunctive form of the verb (were), to show a hypothetical or unreal situation. Chatbots are not humans, but they simulate conversations as if they were human.
Meaning of the words:
-
were – past subjunctive form, used with as if to indicate an unreal/hypothetical condition; grammatically correct.
-
pretend – requires a structure like pretend to be human; without “to be” it is grammatically wrong.
-
could – incomplete and ungrammatical in this context (could another human makes no sense).
-
will – incorrect with as if, because it suggests a definite future action rather than a hypothetical situation.
Correct word: were
Final Sentence: Chatbots are computer programs … as if they were another human.
Hence, the chosen option is correct.
