Target entity: Nectarian period
Context triple: [Mare Nectaris, age, Nectarian period]
  • A. Late Heavy Bombardment era
    The Late Heavy Bombardment era was a hypothesized period about 4.1–3.8 billion years ago during which the inner Solar System, including bodies like the Moon and Mercury, experienced an intense spike in asteroid and comet impacts that heavily cratered their surfaces.
  • B. Noachian
    The Noachian is the oldest major geological era on Mars, characterized by heavy cratering, widespread valley networks, and conditions that may have supported liquid water on the surface.
  • C. Rhyacian Period
    The Rhyacian Period is a geologic time interval in the early Proterozoic characterized by significant crustal growth, widespread metamorphism, and some of the earliest known large-scale glaciations.
  • D. Pragian Epoch
    The Pragian Epoch is an early subdivision of the Devonian Period characterized by the diversification of marine life, especially early fishes and reef-building organisms.
  • E. Stenian Period
    The Stenian Period is the final division of the Mesoproterozoic Era, marked by the assembly of the supercontinent Rodinia and significant geological and tectonic activity roughly 1.2 to 1.0 billion years ago.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
