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: Problem solving, decision making and conflict resolution are all important processes for developing good moral character.

Introduction / Context:
This question tests correct preposition choice after the noun "processes" when we describe purposes, such as developing good moral character. The sentence lists several skills and states that they are important processes for a particular aim. The exam wants you to recognise the most natural and grammatically acceptable preposition in this environment.

Given Data / Assumptions:

• Part 1 lists "Problem solving, decision making and conflict".
• Part 2 continues with "resolution are all important processes".
• Part 3 contains the phrase "to developing good moral character".
• Part 4 is the "No error" option.

Concept / Approach:
When we describe the purpose or intended result of a process, English commonly uses the preposition "for", as in "processes for developing skills" or "methods for improving health". The phrase "to developing" after "processes" sounds awkward and is not idiomatic. We might say "process of developing" or "processes for developing", but "processes to developing" is incorrect. Therefore the preposition in part 3 needs to be replaced with "for" to make the sentence natural and correct.

Step-by-Step Solution:
Read the sentence and identify the segment that looks unusual: "processes to developing".Recall common patterns: "process for developing" and "process of developing" are standard combinations.Recognise that "to" followed by a gerund here does not match usual prepositional usage.Replace "to" with "for", giving "processes for developing good moral character".Verify that the new phrase reads smoothly with the rest of the sentence.

Verification / Alternative check:
After correction, the sentence becomes "Problem solving, decision making and conflict resolution are all important processes for developing good moral character." This version is fully acceptable and clearly conveys that these activities help in the development of moral character. Parts 1 and 2 already formed a correct list followed by a plural verb "are", and there is no other grammatical issue once the preposition is fixed.

Why Other Options Are Wrong:
Part 1 has correct hyphen free gerunds such as "Problem solving" and "decision making" used as nouns. Part 2 correctly continues the list and links it with "are all important processes". Part 4, "No error", cannot be correct because the phrase "processes to developing" is clearly not standard. Thus, the error must be in part 3, where the preposition "to" appears.

Common Pitfalls:
Many test takers see "to" before a verb and think instantly of the infinitive, but here "developing" is already in gerund form. Combining "to" with a gerund after "processes" results in a structure that does not fit any common pattern. It is helpful to learn frequent combinations like "way of doing", "method for doing", "tool for solving", and "process of understanding". Recognising these patterns will help you quickly spot incorrect prepositions in similar questions.

Final Answer:
The error is in part 3 because "processes to developing" should be "processes for developing".
