Question Description
The golden toad of Costa Rica, whose beauty and rarity inspired an unusual degree of human interest from a public generally unconcerned about amphibians, may have been driven to extinction by human activity nevertheless. In the United States, a public relations campaign featuring the toad raised money to purchase and protect the toad’s habitat in Costa Rica, establishing the Monteverde Cloud Forest Preserve in 1972. Although this action seemed to secure the toad’s future, it is now apparent that setting aside habitat was not enough to save this beautiful creature. The toad’s demise in the late 1980s was a harbinger of further species extinction in Costa Rica. Since that time, another twenty of the fifty species of frogs and toads known to once inhabit a 30 square kilometer area near Monteverde have disappeared.The unexplained, relatively sudden disappearance of amphibians in Costa Rica is not a unique story. Populations of frogs, toads, and salamanders have declined or disappeared the world over. Scientists hypothesize that the more subtle effects of human activities on the world’s ecosystems, such as the build-up of pollutants, the decrease in atmospheric ozone, and changing weather patterns due to global warming, are beginning to take their toll. Perhaps amphibians - whose permeable skin makes them sensitive to environmental changes - are the “canary in the coal mine,” giving us early notification of the deterioration of our environment. If amphibians are the biological harbingers of environmental problems, humans would be wise to heed their warning.Q.The author uses the adjective “subtle” in the second paragraph most probably to emphasize thata)these effects are not easily recognized b y sophisticated testing equipmentb)these effects are difficult to notice because they take place over time on a global scalec)these effects are so minimal that they affect only small animal species such as amphibiansd)these slight effects of human activity are rarely discussed by scientistse)these effects are infrequently observed because they affect only specific world regionsCorrect answer is option 'B'.
