In a singly linked structure, each node only knows the location of the next node in the sequence. Therefore, to access the first item, we need to follow the link of the head node, which leads to the first item in the structure. Using the 0 index or getLink(1) would not work because the structure does not provide direct access to the nodes by index. The first() method is not a standard method in most programming languages and would depend on the implementation of the structure.
