Identifying the primary focus of an ecological conservation passage
Question
Which one of the following statements best reflects the most logical, rational and practical suggestion implied by the passage?
Options
It is a cheap and practical method to produce limestone at commercial level for building purposes.
This can be used as one of the methods of carbon sequestration.
Basalt rock can be made a good source of calcium and magnesium minerals by this method.
Good rock-dissolving acid can be produced by mixing carbon dioxide and water.
Explanation
The passage describes a scientific process where injected carbon dioxide reacts with basalt minerals to form solid limestone, permanently locking the gas away[cite: 1893, 1894, 1895]. The fundamental, practical application of turning gaseous ⟨MATH⟩CO_2⟨/MATH⟩ into solid stone is carbon sequestration. Option (a) overreaches by assuming commercial/building viability , option (c) reverses the chemical logic by suggesting mineral extraction , and option (d) mistakes a step in the process for the ultimate objective.
Answer: (b).
