Question

Opponents of weather manipulation argue that the chemicals used in cloud seeding could have a negative impact on the environment. Though many proponents argue that the amount of silver iodide used is negligible, critics feel that there have not been enough studies into how accumulation of the chemical over time could affect plants, animals, and humans on the ground. Many people also worry that weather manipulation could eventually evolve into a form of eco-warfare that would allow countries to harness the power of weather during battle.

Read this paragraph from the passage. Which sentence is MOST appropriate to place at the beginning of this paragraph?
A Of course, not everyone is in favor of messing with Mother Nature.
B The chemicals used in cloud seeding are relatively harmless to humans.
C Scientists agree that weather manipulation is unlikely to be used as a weapon.
D People also feel that there isn’t enough evidence that proves that cloud seeding increases precipitation.

Answer 1

A

Explanation: The paragraph describes opponents' concerns about environmental harm and warfare, so a sentence introducing opposition ("not everyone is in favor...") best fits. Options B and C contradict the paragraph's concerns; D addresses effectiveness rather than opposition.
