24-35: The milk of many mammals contains cannabinoids, substances that are
known to stimulate certain receptors in the brain. To investigate the
function of cannabinoids, researchers injected newborn mice with a chemical
that is known to block cannabinoides from reaching their receptors in the
brain. The injected mice showed far less interest in feeding than normal
newborn mice do. Therefore, cannabinoids probably function to stimulate the
appetite.
Which of the following is an assumption ok which the argument depends?
A)Newborn mice do not normally ingest any substance other than their mothers’
milk.
B)Cannabinoids are the only substances in mammals’ milk that stimulate the
appetite.
C)The mothers of newborn mice do not normally make any effort to encourage
their babies to feed.
D)The mild of mammals would be less nutritious if it did not contain
cannabinoids.
E)The chemical that blocks cannabinoids from stimulating their brain
receptors does not independently inhibit the appetite.
