In a tree repesentated by the hierarchy id, nodes are shown as /1/, /1/1/, /1/2/, /1/2/3/, etc. In this representation, what would the "2" repesent?
Choose your answer:
Nodes at the same level
Nodes in the same subtree
No particular meaning.
The answers listed make no sense in the context of the question asked.
The question is "..what would the "2" represent?" "2" is a singular item, that is not in comparison with anything in the question.
"Nodes at the same level" and "Nodes in the same subtree" are both plural nouns that draw a comparison between the multiple implied items. They cannot be the correct answer to the question because there is nothing in the question for "2" to be "at the same level" as or "in the same subtree" as.
