Answer:
a. As George was the last to touch the greenhouse, we can conclude that he was the one who draped the sterilized materials.
B. Only George had the key to the greenhouse, so he must have stolen the sterile materials.
c. George was seen opening the greenhouse and placing the stylized materials in the backpack before leaving the laboratory. We can therefore conclude that he was responsible for the theft.
Step-by-step explanation:
"Justified on the balance of probability" means that a statement was given with evidence that justifies that statement is correct, that is, there is a context that allows the statement to be made. We can use as an example a laboratory where sterile materials were stolen from the greenhouse where they were kept. A trainee named George was the last one to use the greenhouse, this gives a context for him to be identified as the person who stole the materials.
"Justified beyond reasonable doubt" means that a statement has been taken as correct because there is no logical explanation to prove otherwise. Using the same example given above; if George was the only person who has access to the greenhouse, there is no other suspect in the theft.
"Completely justified" means that the statement has concrete justifications that eliminate any doubts about the truth of the statement. Using the same example, if George was seen stealing the materials, it means that there is nothing to prevent him from being held responsible for the theft.
