Arrange the sentences in the correct sequence to form a coherent paragraph.
A. only 10% of global gold deposits contain sufficient gold to justify further development.
B. The likelihood of a discovery leading to a mine being developed is very low.
C. It requires significant time, financial resources and expertise in many disciplines.
D. Gold mine exploration is challenging and complex.

Correct option is B

The correct order of the sentences to form a coherent paragraph is (b) DCBA.
Explanation:
· D: Sets the stage by stating that "Gold mine exploration is challenging and complex," providing a general introduction to the topic.
· C: Explains the reasons why exploration is challenging, mentioning the "significant time, financial resources, and expertise in many disciplines" required, building directly on the complexity introduced in D.
· B: Adds a layer of information about the low probability of exploration efforts leading to mine development, which is a natural progression from the complexity and resource intensity discussed in C.
· A: Concludes the paragraph by specifying that only "10% of global gold deposits contain sufficient gold to justify further development," which directly ties back to the low likelihood mentioned in B.
This sequence (DCBA) logically progresses from the general complexities and requirements of gold mine exploration to the specific statistic about how rare successful mine development is, effectively building a comprehensive understanding of the challenges in the industry.
