A.I. Explanation:

Correct answer: demand

Explanation: The word 'demand' fits grammatically as it conveys a strong request or requirement that publishers typically have for a translation. It aligns contextually with the idea that publishers require something specific before proceeding with commissioning.

Meaning: 'Demand' means to insist on having something or to require it firmly, indicating that publishers expect a certain level of work from applicants.

Wrong options:

• oblige: 'Oblige' suggests a sense of duty or kindness, which does not convey the authoritative tone needed in this context.
• instruct: 'Instruct' implies giving directions, which is less forceful than 'demand' and does not capture the urgency of the requirement.
• direct: 'Direct' suggests guiding or managing, but it lacks the connotation of necessity that 'demand' carries.

Correct answer: specimen

Explanation: The term 'specimen' is appropriate as it refers to an example or sample of the applicant's work, fitting well within the context of showcasing their abilities. It is grammatically correct as it serves as a noun that complements the preceding clause.

Meaning: 'Specimen' means a sample or example used for examination or display, particularly in this context to show the quality of work.

Wrong options:

• instance: 'Instance' refers to a particular case or occurrence, which does not convey the idea of a sample of work as effectively as 'specimen.'
• case: 'Case' is too vague and does not specifically imply a sample of work, making it less suitable in this context.
• model: 'Model' suggests a representation or example but does not align with the idea of a sample of work that is being evaluated.

Correct answer: eager

Explanation: The word 'eager' fits well as it conveys enthusiasm and readiness, which is appropriate for someone looking to translate. It matches the grammatical structure and context of the sentence, indicating a positive attitude towards the task.

Meaning: 'Eager' means having a keen interest or enthusiasm for something, suggesting that the translator is excited about the opportunity to work.

Wrong options:

• nervous: 'Nervous' implies anxiety, which does not fit the positive context of beginning a translation project.
• agitated: 'Agitated' suggests a state of disturbance or anxiety, which is contrary to the desired enthusiasm for the task.
• excited: While 'excited' conveys enthusiasm, it is less formal than 'eager' and does not fit the tone of the sentence as well.

Correct answer: substantial

Explanation: The word 'substantial' is appropriate as it indicates a significant or considerable amount, which is necessary for a translation sample. It fits grammatically and contextually, emphasizing the importance of the section being translated.

Meaning: 'Substantial' means considerable in quantity or importance, suggesting that the section should be meaningful and representative of the work.

Wrong options:

• main: 'Main' implies primary importance but does not convey the idea of quantity or size as effectively as 'substantial.'
• grand: 'Grand' suggests something impressive or large but does not fit the context of describing a section of a book.
• plentiful: 'Plentiful' refers to abundance but lacks the nuance of significance that 'substantial' carries.

Correct answer: suitable

Explanation: The word 'suitable' is fitting as it indicates appropriateness for the context of submitting work to a publisher. It aligns grammatically and contextually, suggesting that the publisher should be a good match for the translator's work.

Meaning: 'Suitable' means appropriate or fitting for a particular purpose, indicating that the publisher should align with the translator's style and work.

Wrong options:

• fit: 'Fit' is too informal and does not convey the same level of appropriateness as 'suitable.'
• right: 'Right' is vague and does not specifically indicate the appropriateness needed in this context.
• convenient: 'Convenient' suggests ease of access rather than appropriateness, making it less suitable for this context.
