true | The excerpt states that binary search works on sorted collections and has O(log n) time complexity, directly supporting the claim. | A binary search on a sorted array can locate a target value in O(log n) time. | supports | Binary search applies to sorted collections. Each comparison eliminates approximately half of the remaining search interval, giving the algorithm a time complexity of O(log n). |
not_enough_info | The excerpt describes Python's characteristics and programming styles but gives no information about the date of its first public release. | The first public release of Python occurred in 1991. | insufficient | Python is a high-level, interpreted programming language.

Online Course Caption Fact Verification Benchmark
This benchmark focuses on factual claims extracted from transcripts of online course videos and pairs them with relevant web text evidence, verification verdicts, evidence relations, and rationales. Designed for online education content, it supports evaluation of whether models can determine claim validity from textual evidence, assess how the evidence relates to a claim, and explain their decisions. It is suitable for fact-checking system development, model comparisons, and evidence reasoning research.
