In the following English grammar error detection question, identify the part of the sentence that contains an error, or choose "No error" if the sentence is correct: Character build should be an integral part of every aspect of schooling and learning as it equips an individual to find long term solutions to the challenges of life.

Introduction / Context:
This question checks your familiarity with standard noun patterns in English, especially the correct form of expressions like "character building". The sentence describes how education should shape personality and moral strength. Your task is to identify the segment that is grammatically or idiomatically incorrect.

Given Data / Assumptions:

• The key phrase in part 1 is "Character build should be an integral part".
• Parts 2 and 3 speak about schooling, learning, and long term solutions.
• The focus is not on deep vocabulary but on natural collocations commonly used in educational and moral contexts.
• "Character building" is a well known phrase in English.

Concept / Approach:
In English, when we talk about developing moral strength and personality, the correct expression is "character building", not "character build". Here, "building" is a gerund that functions as a noun, and the whole phrase "character building" means the process of developing character. The phrase "character build" usually does not appear in formal English in this sense. Therefore, part 1 contains a collocation error that needs to be corrected to "Character building should be an integral part".

Step-by-Step Solution:
Read the whole sentence and identify expressions that feel unnatural.Focus on the opening phrase "Character build should be an integral part".Recall that the standard phrase is "character building" when referring to moral development.Substitute "build" with "building" to obtain "Character building should be an integral part".Check the remaining parts: "of every aspect of schooling and learning as it equips an individual to find long term solutions to the challenges of life" are structurally sound.

Verification / Alternative check:
The corrected sentence reads: "Character building should be an integral part of every aspect of schooling and learning as it equips an individual to find long term solutions to the challenges of life." This is a natural, idiomatic sentence that you might find in educational philosophy texts and exam passages. No other part shows any clear grammatical error.

Why Other Options Are Wrong:
Part 2 correctly uses "of every aspect of schooling and learning as it". Part 3 uses "equips an individual to find long term solutions to the challenges of life", which is appropriate in meaning and grammar. Part 4, "No error", is incorrect because part 1 clearly contains a faulty phrase. Therefore, part 1 is the only segment that needs correction.

Common Pitfalls:
Many learners are aware of the word "build" and may overextend its use, assuming that it can always substitute for "building". However, English has many fixed phrases where only one grammatical form is acceptable, such as "character building", "decision making", or "problem solving". Memorising common collocations is very useful in error detection sections, because the examiners often test these fixed patterns rather than complex structures.

Final Answer:
The error is in part 1 because "Character build" should be "Character building".
