Of the given four options, choose the one sentence that has no errors.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2, i.e. Sam was very noticeable in his class, and his friendly behavior endeared him to others.
Error concept: Unnecessary repetition/redundancy
What is wrong: In option 3, the phrase “self-destruct on its own” is redundant. The word “self-destruct” already means to destroy on its own, so saying “on its own” again is repeating the same idea unnecessarily.
Grammatical concept: In English grammar, when a word already includes a meaning, we do not repeat that same idea using another word. This is called redundancy, and it should be avoided in standard grammar.
Incorrectness of the concept in context: The sentence “The app was devised in such a way that it could self-destruct on its own” is not correct, because “self-destruct” already means that the app destroys itself, so “on its own” is not needed.
How to correct: We should either write “self-destruct” or “destruct on its own”, not both.
Correct phrase/ correction: “The app was devised in such a way that it could self-destruct within a particular period of time.”
Final sentence: Among all four options, only option 2 is completely error-free.
Hence, the chosen option is correct.
