Answer:

Hello. You did not give the answer options, but observing the information given in the question and using deductive reasoning, we can say that the order in which the characters are located in the queue, from the first to the last are: Greta, Lori, Lilly, Ivan , Jack and Helen.

Explanation:

Deductive reasoning is one that is constructed from the logic shown by premises that were previously presented. For example, if I speak of the premise that bats are mammal animals, I can conclude that bats have lungs, since, logically, all marine animals have lungs.

Thus, through the premises shown in the question above, we can deduce what is the order of the characters in the queue and who is in front of whom.
