Biologist Dr. Amy Park argues that CRISPR gene editing could eliminate malaria by modifying mosquito populations to be incapable of transmitting the parasite.

readingWhich research finding would best support Park's elimination potential?
A
Malaria kills many people
B
Mosquitoes transmit malaria
C
CRISPR technology is advancing
D
Gene-drive mosquitoes releasing anti-malaria genes spread the modification to 95% of wild populations within 10 generations in contained trials, rendering them unable to carry the parasite
Correct Answer: D
Choice D is the best answer. 95% spread + functional result (unable to carry) proves intervention can work at scale.
💡 Strategy: Biological intervention claims need demonstrated efficacy AND spread mechanism.
