Rashan thought that he would be dramatic and impress his public speaking class with his speech on air pollution. He decided to use mice in a closed jar to illustrate how air pollution is slowly killing human beings. But during his speech, the jar fell off the desk and the mice escaped, distracting his audience and putting an abrupt end to his presentation. What guideline did Rashan ignore, with regard to using presentation aids?

Answer:

Rashan neglected the rules that are taken to care for the animals that are used in the laboratory. Rashan was irresponsible because everyone who uses  animals for scientific research must take responsibility for the welfare of these animals.

On the other hand it is important to highlight that it was not necessary to bring the animals to class, it was enough to explain their experimental design on a billboard and emphasize the results of their research without distracting.
