"hard" = difficult

Please re-think.

To determine the correct answer, we need to consider each option and examine the factors that make mining in Cerro Rico mountain difficult:

A. Distance from the city of Potosi: While distance might pose logistical challenges, it alone does not make mining exceptionally hard. Therefore, we can eliminate this option.

B. Isolation from other workers: Isolation can certainly present difficulties, especially in terms of accessing resources and support. However, it is not the main reason why mining in Cerro Rico mountain is known for being challenging. Therefore, we can eliminate this option.

C. Dangerous working conditions and low pay: This option highlights one of the key factors that make mining in Cerro Rico mountain so hard. The working conditions in the mines are extremely dangerous due to factors such as lack of modern safety measures, inadequate ventilation, and unstable tunnels. Additionally, the pay is typically low, which further adds to the hardships faced by the miners. So, this option is a valid choice.

D. Lack of job security: While job security can contribute to the overall difficulty of working in the mines, it is not the main focus of what makes mining in Cerro Rico mountain particularly hard. Therefore, we can eliminate this option.

Based on the analysis above, the correct answer is C. Dangerous working conditions and low pay.
