Black holes are the most efficient engines of destruction known to humanity. Their intense gravity is a one-way ticket to oblivion, and material spiraling into them can heat up to millions of degrees and glow brightly. Yet, they are not all-powerful. Even super massive black holes are minuscule by cosmic standards. They typically account for less that one percent of their galaxy’s mass. Accordingly, astronomers long assumed that super massive holes, let alone their smaller cousins, would have little effect beyond their immediate neighborhoods. So it has come as a surprise over the past decade that black hole activity is closely intertwined with star formation occurring farther out in the galaxy.
Q: Which of the following most resembles the relationship between “black hole activity” and “star formation” (lines11-12) as described in the passage?
(A) A volcanic eruption on one continent results in higher rainfall totals on another continent.
(B) Industrial emissions in one region lead to an increase an airborne pollutants in adjacent regions.
(C) A drought in a wilderness area causes a significant loss of vegetation in that area
(D) Decreased oil production in one country results in higher gas prices in oil-dependent countries.
(E) Overfishing in a gulf leads to an increase in the population of smaller aquatic organisms.
