An amendment to the original Quartering Act was passed on June 2, 1774. This act was passed and enforced, along with many others, known by the colonists as the 'Intolerable Acts'.
Answer:
The elephants were prevented from seeing the signals to prevent or minimize the chances of <em>Cueing</em>.
Explanation:
In psychology, the action of giving a clue or prompt to another person (in this case the Elephants) in order to receive a response is called a <em>cued recall </em>or <em>cueing</em>.
It was a method incorporated into the experiment with the Elephants to ensure that the procedure was <em>controlled</em>.
An experiment in which all factors are held constant except for one: the independent variable is referred to as a controlled experiment.
If an experiment is not controlled, then it is difficult or impossible to say with all certainty whether or not the Hypotheses being tested for is True or False.
