Which of the following would be the correct rearrangement of the given sentences?

To determine the correct rearrangement of the sentences, we need to analyze the logical flow, chronological sequence, and thematic connections between the sentences.

Let's examine the role of each sentence:
- (D) introduces John's experience with learning foreign languages as unique, attributing it to a unique upbringing. This serves as a strong introductory sentence that sets the stage for his story.
- (B) elaborates on this "unique upbringing" by explaining the specific household environment: growing up with parents who spoke different languages.
- (F) explains the immediate effect of this early exposure (from the household described in B), stating it sparked his interest and instilled a lifelong passion.
- (A) moves forward chronologically: "As he grew older, John's dedication... became more apparent..." which naturally follows the early-stage spark described in (F).
- (E) explains how he managed this growing dedication: "With his innate talent... he was able to quickly assimilate new vocabulary..." detailing his learning process.
- (C) concludes the narrative flow by describing the ultimate outcome of his lifelong commitment: "...John went on to become proficient in several languages and pursued a career as a highly-skilled translator."

Following this logical and chronological sequence, the correct order is D - B - F - A - E - C.

Therefore, the correct rearrangement is DBFAEC.
