Which employee qualifies as a longshoreman?

A longshoreman is specifically defined as a worker who is involved in loading and unloading cargo from ships at the dock. This role is critical to maritime activities, as longshoremen are responsible for the physical handling of goods as they are transferred between land and sea transport. The key aspect of this definition is the direct involvement with the loading and unloading processes at the docks, which distinguishes them from other roles associated with maritime operations.

In contrast, the other options refer to different types of maritime-related work that do not fall under the traditional definition of a longshoreman. For instance, working aboard an ocean liner out at sea does not involve the direct handling of dockside cargo, and similarly, a truck driver hauling a load from a ship is involved in transportation logistics rather than the direct loading or unloading activities. A shoreline restoration firm focuses on environmental aspects and is not related to the unloading and loading of maritime cargo. Thus, the role of a longshoreman is specifically tied to dockside operations, making the second choice the accurate answer.
