Which of the following would be the FIFTH sentence after rearrangement?

To determine which sentence comes fifth, we need to logically rearrange the given sentences into a coherent paragraph.

Let's analyze the theme and logical flow of each sentence:
- (A) describes John's continued dedication to learning as he grew older (school and independent learning).
- (B) introduces the starting point of John's life: growing up in a multilingual household.
- (C) details the culmination of his journey, where he became a professional translator.
- (D) serves as a reflective concluding summary about John's unique experience and upbringing.
- (E) describes his innate talent and ability to master linguistic concepts during his learning phase.
- (F) links the early exposure in the household to his sparked interest and lifelong passion.

Now, let's reconstruct the logical order step-by-step:
1. First Sentence: (B) - This is the best starting sentence as it introduces John's childhood background (growing up in a household with parents speaking different languages).
2. Second Sentence: (F) - This naturally follows (B), explaining that this early exposure in the household sparked his interest in languages.
3. Third Sentence: (E) - Building on his sparked interest, this sentence describes his innate talent and quick assimilation of vocabulary and grammar rules.
4. Fourth Sentence: (A) - This marks a chronological progression ("As he grew older..."), detailing his continued dedication during school and independent study.
5. Fifth Sentence: (C) - This shows the ultimate result of his dedication ("went on to become proficient... and pursued a career as a highly-skilled translator").
6. Sixth Sentence: (D) - This provides a final reflective summary statement about his overall unique journey.

Therefore, the complete logical sequence is B → F → E → A → C → D.

The fifth sentence in this rearrangement is C.
