Final answer:
Unsophisticated means not complex or refined, often hinting at naturalness or innocence, especially in the context of 'The Boy in the Striped Pyjamas', where it could indicate a character's naïve worldview.
Step-by-step explanation:
Unsophisticated generally means not complex or refined and often implies a natural, innocent, or straightforward character. In the context of 'The Boy in the Striped Pyjamas', the term could refer to a character's naïve or innocent view of the world, untouched by the complexities and harsh realities of adult life. It could also suggest a lack of awareness or understanding of the grim and complex historical events taking place around them. Moreover, unsophistication may manifest through simple language, actions, and perceptions that reflect a child's unblemished viewpoint.
In the provided text, the female character protests any implication of being sophisticated, equating sophistication with being 'common' and lacking innocence. She emphasizes her girlish innocence and simple lifestyle, claiming to be untouched by vices or complex knowledge—characteristics typically associated with a more sophisticated adult world. Thus, her interpretation of unsophisticated is aligned with a pure, wholesome manner of living and a preference for simple pleasures over more adult experiences and knowledge.
