Factors that can affect the utility of radiocarbon dating include all of the following except
a. contamination (e.g., by coal).
b. atmospheric fluctuations of 14C.
c. organisms that obtain their carbon from sources whose carbon content may be significantly different from that of the atmosphere.
d. physiological differences between male and female skeletons
e. differences in the carbon-14 intake between maize plants and oak trees
Question 2
Fluctuations in the radiocarbon-dating calibration curve are produced by variations in the atmosphere's carbon-14 content; these cause radiocarbon dates to calibrate to more than one calendar age. This is due to
a. De Vries effect.
b. the reservoir effect.
c. the effect of different photosynthetic pathways.
d. problems with calibrating the radiocarbon curve.
e. Nelson effect.
