In management, as you rise higher,
the problems you face become more and more unstructured and you can't just fall back on
the tools you had been
No error
Answer is Right!
Answer is Wrong!
The correct answer is D. No error.
The sentence is grammatically correct. The past participle “been” is used correctly as an adjective to modify the noun “tools.” The sentence means that as you rise higher in management, the problems you face become more complex and you cannot rely on the same methods and solutions that you used when you were at a lower level.
The other options are incorrect because they contain grammatical errors. Option A is missing a comma after the word “higher.” Option B is missing a verb after the word “become.” Option C is missing a subject before the word “had been.”
