Table 3: Examples that compare closed-book and open-book GPT-3 answers with top-5 articles from Google custom search (GCS) retrieval. As in the first three examples, GPT-3 can adjust its answer based on newly-retrieved documents. When the retrieved documents are outdated or unrelated, however, GPT-3 ignores the temporal gap and yields an outdated answer.
