Final answer:
In a quarry, workers are generally provided with hammers by the management (option c), which are necessary for them to work effectively. Acheulean tools are best described as hand-axes made by chipping stones. Appropriate equipment, like a mechanical scoop, is needed to move big boulders.
Step-by-step explanation:
The question "How do people in the quarry manage if they do not have hammers?" concerns the tools and resources available to workers in a quarry setting. The correct answer to this is option c, which states they are provided with hammers by the quarry management. This is the norm in a quarry operation since hammers and other tools are essential for the workers to efficiently and safely extract stone and other materials from the earth. Without the proper tools, such as hammers, workers cannot perform their duties effectively.
Acheulean tools are best described by option a, as hand-axes made by careful chipping of stones. These were prehistoric stone tools used by early humans, showing the evolution of tool-making skills. Stone blades attached to handles describe a different stage in tool development.
When considering moving a boulder or a pile of rocks, it's essential to assess the size of the rocks and determine the appropriate equipment for the task. For small rocks, a shovel may be sufficient, while larger rocks could be moved by hand. However, for moving big boulders, mechanical equipment like a scoop is necessary. This process requires consideration of the amount and size of the rocks to properly prepare and allocate the necessary time for the job.
