Final answer:
The correct answer is option B, stating that coffee grinders simplified the brewing process for pioneers. Other options are incorrect due to lack of evidence or overgeneralization.
Step-by-step explanation:
The correct response to the student's question is option B: Coffee grinders made life simpler for some pioneers because they could just turn a handle to get freshly ground coffee beans. This statement is true, as having a coffee grinder would have made the process of preparing coffee easier compared to the more labor-intensive method of crushing beans with a tool such as a camp axe or hammer.
Option A is incorrect because there is no evidence to suggest that coffee tastes better when beans are crushed with a hammer, and Option C and D make unwarranted generalizations. Not all pioneers had to be wealthy to drink coffee; they might have used alternative methods for preparing it, while some more established families might indeed have possessed a coffee grinder.
The preparation and consumption of coffee goes back to its origins in Ethiopia and its notable impact on world history through the coffee trade routes from Yemen. Coffee's significance in various cultures, including the Ottoman Empire, is evident with its association with social interactions and intellectual exchange.
