A De-Icing Experiment
Some species of plants that commonly grow
near roadways are used in an experiment.
The plant species are divided into control
groups and experimental groups. All groups
are grown under identical conditions except
that the experimental groups are given daily
applications of a de-icing solution that is used
on roadways in winter. At the end of one
month, the growth of the control and
experimental groups is compared.
5 Which of the following is the most likely
hypothesis for the experiment described
A Vegetation that grows near roadways
requires more water than vegetation in
B De-icing solution causes roadways to have
more space for vegetation.
C Vegetation near roadways changes the
effectiveness of de-icing solution.
