The assessment is based on direct, explicit, and highly authoritative primary source evidence. Source 3, the official ETH/USD spot trading page on OKX, provides the most direct confirmation, stating a "24h high" of $4,087.18. This figure is unequivocally greater than $4,000, directly proving the statement to be true. This evidence is of the highest quality as it comes from the exchange platform itself, reflecting actual market data. This key piece of evidence is strongly supported by a consensus of other primary sources from OKX (Sources 1, 2, 4, 5, and 6), which are all official pages dedicated to tracking Ethereum's price on the platform. There are no contradictions among the relevant sources. The remaining sources are correctly identified as either irrelevant (concerning different cryptocurrencies or exchanges) or less relevant (concerning derivative products), and therefore do not detract from the conclusion. The consistency and authority of the supporting evidence lead to a high-confidence conclusion that the statement is true.
