Question 3: As with other river deltas, the Indus River delta is ; it is a constantly evolving network of channels and strips of land that change in size and shape as the river deposits new sedimentary particles where the river meets the waters of the Arabian Sea. Which choice completes the text with the most logical and precise word or phrase? A) dynamic B) sustainable C) immutable D) unrivaled Explain: A) dynamic - This is the correct answer because it perfectly captures the changing nature of the delta described in the text. The sentence explicitly mentions "constantly evolving," "change in size and shape," and ongoing deposition of sedimentary particles. "Dynamic" precisely describes systems that continuously change and transform over time, which aligns exactly with the characteristics of the delta outlined in the passage. B) sustainable - This option is inappropriate because the passage focuses on the delta's changing physical characteristics, not its ecological longevity or environmental balance. While deltas may support sustainable ecosystems, the text specifically describes physical transformation processes rather than sustainability features. The word fails to capture the central idea of continuous change. C) immutable - This word means unchangeable or permanent, which directly contradicts the entire description provided in the text. The passage explicitly states the delta is "constantly evolving" and "changes in size and shape" - the exact opposite of immutable. This option creates a logical contradiction with the rest of the sentence. D) unrivaled - This option suggests the delta is superior to others or without equal, but the passage makes no comparisons regarding the delta's superiority. In fact, the opening phrase "As with other river deltas" explicitly establishes similarity to other deltas, not uniqueness. The text focuses on describing physical characteristics rather than making comparative judgments.
