As the news of the atomic attack reached Einstein, he is becoming aware of the glaring
horror of the abuse of atomic energy.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. became aware of.
Error Concept: related to the incorrect verb tense.
What is wrong: The sentence uses “he is becoming aware”, which is present continuous tense. But the main action “as the news… reached” is in past tense.
Grammar Concept: When an action happened in the past, the verb must also be in the past tense for consistency.
Incorrectness of the concept in context: Using “is becoming” (present continuous) with “reached” (past tense) creates a tense mismatch.
Correction: Replace “is becoming aware of” with “became aware of”.
Corrected phrase: became aware of.
Final sentence: As the news of the atomic attack reached Einstein, he became aware of the glaring horror of the abuse of atomic energy.
Hence, the chosen option is correct.
