the following is an excerpt from

silent spring by rachel carson.
it was a spring without voices. on the mornings that had once throbbed with the dawn chorus of robins, catbirds, doves, jays, wrens, and scores of other bird voices there was now no sound; only silence lay over the fields and woods and marsh.

on the farms the hens brooded, but no chicks hatched. the farmers complained that they were unable to raise any pigs—the litters were small and the young survived only a few days. the apple trees were coming into bloom but no bees droned among the blossoms, so there was no pollination and there would be no fruit.

the roadsides, once so attractive, were now lined with browned and withered vegetation as though swept by fire. these, too, were silent, deserted by all living things. even the streams were now lifeless. anglers no longer visited them, for all the fish had died.

in the gutters under the eaves and between the shingles of the roofs, a white granular powder still showed a few patches; some weeks before it had fallen like snow upon the roofs and the lawns, the fields and streams.

no witchcraft, no enemy action had silenced the rebirth of new life in this stricken world. the people had done it themselves.

this town does not actually exist, but it might easily have a thousand counterparts in america or elsewhere in the world. i know of no community that has experienced all the misfortunes i describe. yet every one of these disasters has actually happened somewhere, and many real communities have already suffered a substantial number of them. a grim specter has crept upon us almost unnoticed, and this imagined tragedy may easily become a stark reality we all shall know.

what has already silenced the voices of spring in countless towns in america? this book is an attempt to explain.

what is the explicit claim made by carson in this passage?
a.
all of the birds, fish, and plants will soon die due to the damage done by the people.
b.
birds no longer sing in the trees because all of the trees have died.
c.
fruit trees cannot grow fruit without birds and bees to sing to them.
d.
many of the things described in the imaginary town have happened in real towns all over america.
