  • A. 4.2 kiloyear event chosen

  • D. Holocene climatic optimum
    The Holocene climatic optimum was a warm period roughly 9,000–5,000 years ago when global temperatures, especially in the Northern Hemisphere, were higher than today, influencing the spread of forests and early human civilizations.
