Question 8 • CA-Common Core English Language Arts 11 B
Read the excerpt from "The Environmental Ethic."It is fashionable in some quarters to wave aside the small and obscure, the bugs and weeds, forgetting that an obscure moth from Latin America saved Australia’s pastureland from overgrowth by cactus, that the rosy periwinkle provided the cure for Hodgkin’s disease and childhood lymphocytic leukemia, that the bark of the Pacific yew offers hope for victims of ovarian and breast cancer, that a chemical from the saliva of leeches dissolves blood clots during surgery, and so on down a roster already grown long and illustrious despite the limited research addressed to it.Which of the following claims is best supported by the evidence in this excerpt?
Answer
A
All species are worth protecting because even the small organisms contribute important functions in the environment.
B
Every effort should be made to protect each bug and weed species regardless of its potential to cause destruction.
C
All of the species that are now extinct or are becoming extinct could have cured a disease.
D
Only the species that can be used for medical purposes are worth protecting from extinction.
Explanation
The excerpt gives examples of small or obscure organisms with important benefits: a moth helped protect Australia’s pastureland, and plants and leeches have provided substances used in medicine. These examples support the claim that even small organisms can play valuable roles. The excerpt does not say every species can cure a disease or that only medically useful species deserve protection.
