Error Spotting – Choose the segment (A–D) that contains a grammatical error; select “No error” only if the entire sentence is correct. Sentence: A) What is needed today is B) a new breed of managers C) with a new set of concepts D) and a flexible way about thinking.

Introduction / Context:
This question checks idiomatic prepositional pairing with “way”. In English, the fixed expression is “way of doing/thinking”, not “way about thinking”.

Given Data / Assumptions:

• Predicate nominative structure: “What is needed today is …”.
• Coordinate NP culminates in “a flexible way about thinking”.
• Target idiom: “way of thinking”.

Concept / Approach:
“Way” meaning “manner/method” takes the preposition “of” before a gerund or verbal noun: “way of working/thinking”. Using “about” is unidiomatic in this frame.

Step-by-Step Solution:
1) Identify the collocation head “way”.2) Replace “about” with “of”.3) Correct sentence: “What is needed today is a new breed of managers with a new set of concepts and a flexible way of thinking.”4) Therefore, D is the erroneous segment.

Verification / Alternative check:
Check comparable idioms: “method of”, “manner of”, “style of” — all pair with “of” plus gerund/noun, reinforcing the pattern.

Why Other Options Are Wrong:

• A–C: Grammatically and semantically fine; the problem is solely the preposition in D.

Common Pitfalls:
Using “about” after “way” due to semantic association with “thinking about”; however, the idiom governs the choice here.

Final Answer:
Option D
