Climate scientist Dr. Emily Chen argues that geoengineering research should proceed despite risks because climate change may force emergency deployment, and unresearched interventions would be more dangerous.

Which risk analysis would best support Chen's research argument?

A

Climate change is serious

B

Some geoengineering methods exist

C

Research is valuable

D

Models show 30% chance of crossing 2°C threshold triggering calls for emergency deployment; researched interventions would reduce side-effect risks by 80% compared to unresearched deployment—the question is not whether but how prepared we are

Correct Answer: D

Choice D is the best answer. Quantified deployment probability + risk reduction from research proves preparation argument.

💡 Strategy: "Should prepare for X" claims need probability of X plus benefit of preparation.
