Answer:
a. control; experimental
Explanation:
A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
On the other hand, an experimental group can be defined as a collection of participants that are subjected to the independent variable.
Most experiments have a control group for purposes of comparison. This group is not given the treatment or the same independent variable as the experimental group.
Therefore, this is the reason why science completely or totally rejects any hypothesis which is not supported by observations, as well as the results obtained from control experiments.
This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.
Answer: Case law
Explanation: Case laws are a compilation of reported cases which forms a body of law within a certain jurisdiction. They contain written legal decisions which have been made by a court in the past, and are thus employed in making verdict on current or present cases. In case laws, judges adhere to the principle of making current decisions based on verdict passed on previous related rulings. This principle is called stare decisis. The rule of precedence is employed when security operatives or professionals form part of an investigative panel resulting in the trial of a criminal.
