precisely. Which of the following is a reasonable conclusion?
A) Radiocarbon dating is not a good dating technique or it could separate the ages of
the slides.
B) There was probably an earthquake ~1000 years ago.
C) There must have been a major drought 1000 years ago that triggered the landslides.
D) There must have been people in the area 1000 years ago, and they cut down the trees
that were dated for determining the age of the landslide.
