Refer to the exhibit. You called the Key Phrase Extraction API on two documents. What is the total number of key phrases extracted?

⚠ Common exam trap

The trap here is that candidates often deduplicate key phrases across documents, thinking the API returns a global set, but the API returns results per document and the question explicitly asks for the total number extracted from both documents, which requires summing the per-document counts.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The Key Phrase Extraction API returns a list of key phrases per document. In this case, Document 1 returns 'weather', 'Seattle', and 'rainy', while Document 2 returns 'weather' and 'Seattle'. The total number of unique key phrases across both documents is 3 ('weather', 'Seattle', 'rainy'), but the question asks for the total number of key phrases extracted, which counts each occurrence per document. That gives 3 + 2 = 5 key phrases. Option B is correct because the API outputs phrases per document, not deduplicated globally.
