In the diagram, what process happens at Step 4?
A. A team of scientists must form
a committee to discuss the
hypothesis.
B. The results of the experiment
must be published along with
a ballot so that other scientists
can vote on whether they sup-
port or reject the hypothesis.
C. The scientist or team of scien-
tists who formulated the
hypothesis must do the sup-
porting experiment over and
over again to be sure they have
it right.
D. The results of the experiment
must be published so that the
experiment can be repeated by
other scientists, along with
additional experiments to prove
or disprove the hypothesis.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
