Full Explanation
Token-to-word conversion for English: approximately 1 token = 0.75 words, or 1 word = ~1.33 tokens. So 200,000 tokens ≈ 150,000 words. A typical novel is 70,000-100,000 words; a typical Harry Potter book is around 77,000-257,000 words. This means Claude's 200K context can hold: the complete text of 2-3 average novels, thousands of pages of legal documents, entire codebases of medium-sized projects, or months of email threads. Option A (50 pages) dramatically underestimates. Option C (sentences) is a meaningless unit since sentence lengths vary wildly. Option D (spoken speech) is completely wrong — 2 minutes ≈ 300 words.
