Final answer:
In a linear search for 'emu', each item in the list is examined sequentially until 'emu' is found or the end is reached; the items checked depend on 'emu's position.
Step-by-step explanation:
When performing a linear search to find the item emu, each item in the list or array is examined in sequence until the desired item is found or the end of the structure is reached. This means that if the search is conducted on an array of items, the search process will start with the first item and continue in order, one by one, until it either locates emu or reaches the conclusion of the array without finding it. The specific items that will be examined depend on their positions in the array relative to emu. If emu is the fifth item in the array, for example, the search algorithm will look at the first five items.
