Question Statement:
Claim: 'Adopting biological pest control using parasitic wasps is completely sufficient to protect all commercial cotton orchards against bollworm damage.' Which fact most weakens this claim?
Options:
(A) Parasitic wasps are rendered inactive when ambient temperatures exceed 38$^{\circ}$C, which coincides precisely with peak bollworm infestation periods.
(B) Parasitic wasps do not sting humans.
(C) Chemical pesticides cost more than rearing wasps.
(D) Cotton flowers produce nectar that attracts pollinators.
Answer Key:
A
Step-by-Step Solution & Explanation
Thermal inactivity during peak infestation breaks the control mechanism, seriously weakening the claim of total sufficiency.
