Target entity: Last Glacial Maximum Context triple: [Northern Hemisphere ice sheets, maximumExtentDuring, Last Glacial Maximum]
-
A.
Last Glacial Maximum
chosen
The Last Glacial Maximum was the most recent period in Earth’s history when ice sheets reached their greatest extent, dramatically lowering sea levels and reshaping global climates and ecosystems.
-
B.
Last Glacial Period
The Last Glacial Period was the most recent major ice age, spanning roughly 115,000 to 11,700 years ago, during which large ice sheets covered vast areas of North America, Europe, and Asia and global climates were significantly colder and drier than today.
-
C.
Saalian glaciation
The Saalian glaciation was a major Middle Pleistocene ice age in northern Europe, during which extensive ice sheets covered large parts of the continent.
-
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.
-
E.
Pleistocene epoch
The Pleistocene epoch was a geological time period characterized by repeated ice ages, widespread glaciation, and the evolution and global spread of modern humans.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
