Meaning: 'Who' is used to refer to people, in this case, indicating that the pupils are the ones using visual art as a stimulus.

Wrong options:

• when: The word 'when' indicates time and does not relate to the subject of pupils, making it grammatically incorrect in this context.
• what: The word 'what' is used to refer to things or ideas, not people, thus it does not fit the grammatical structure needed here.
• where: The word 'where' indicates a place, which is irrelevant to the subject of pupils and their actions.

Correct answer: elaborate

Explanation: The word 'elaborate' fits contextually as it means to add more detail or complexity to something. It aligns with the idea of enhancing the writing process by adding details, making it the most suitable choice grammatically and contextually.

Meaning: 'Elaborate' means to develop or present in detail, which is appropriate in the context of enhancing written work.

Wrong options:

• supplement: The word 'supplement' implies adding something extra, but it does not convey the same depth of detail as 'elaborate' in this context.
• ornament: The word 'ornament' suggests decoration rather than adding substance, which does not fit the context of enhancing writing.
• decorate: The word 'decorate' implies beautifying rather than adding depth or detail, making it less suitable than 'elaborate'.
• complicate: The word 'complicate' suggests making something more difficult, which is contrary to the intended meaning of enhancing clarity in writing.

Correct answer: mechanics

Explanation: The word 'mechanics' refers to the technical aspects of writing, such as grammar and syntax, making it the correct choice. It fits grammatically as it describes the challenges faced by emergent writers in the writing process.

Meaning: 'Mechanics' in this context refers to the rules and techniques involved in writing, including spelling and grammar.

Wrong options:

• workings: The word 'workings' is too vague and does not specifically refer to the technical aspects of writing, making it less precise than 'mechanics'.
• implements: The word 'implements' refers to tools or instruments, which does not accurately describe the challenges in writing mechanics.
• materials: The word 'materials' suggests physical items rather than the skills and rules of writing, making it an inappropriate choice.
• apparatus: The word 'apparatus' implies a complex structure or equipment, which does not fit the context of writing skills.

Correct answer: approach

Explanation: The word 'approach' refers to a method or way of doing something, which fits well in the context of discussing different methods of writing. It is grammatically correct and contextually relevant to the comparison being made.

Meaning: 'Approach' means a way of dealing with something, in this case, the method of writing that is being contrasted with the traditional method.

Wrong options:

• style: The word 'style' refers to a manner of doing something but does not convey the methodical aspect implied by 'approach'.
• scheme: The word 'scheme' suggests a plan or arrangement, which does not accurately reflect the method of writing being discussed.
• manner: The word 'manner' refers to a way of doing something but lacks the specificity of 'approach' in this context.
• organization: The word 'organization' refers to the structure of writing rather than the method, making it less suitable than 'approach'.
