Q12)Conclusion Question

Journalist: Obviously, though some animals are purely carnivorous, none would survive without plants. But eh dependence is mutual. Many plant species would never have come to be had there been no animals to pollinate, fertilize, and broadcast their seeds. Also, plants’ photosynthetic activity would deplete the carbon dioxide in Earth’s atmosphere were it not constantly being replenished by the exhalation of animals, engine fumes, and smoke from fires, many set by human beings.

Which one of the following most accurately expresses the main conclusion of the journalist’s argument?
(A) The photosynthetic activity of plants is necessary for animal life, but animal life is also necessary for the occurrence of photosynthesis in plants.
(B) Some purely carnivorous animals would not survive without plants.
(C) The chemical composition of Earth and its atmosphere depends, at least to some extent, one the existence and activities of the animals that populate Earth.
(D) Human activity is part of what prevents plants from depleting the oxygen in Earth’s atmosphere on which plants and animals alike depends.
(E) Just as animals are dependent on plants for their survival, plants are dependent on animals for theirs.

12. - E
The arguments want to highlight the dependence between plant and animals. Terms/words like Photosynthesis process, human activity, Co2 have been presented to support the argument and serve as examples

Conclusion of the stem is the 2nd statement: But The dependence is mutual.
The main idea is nothing but the conclusion of the stem. If conclusion is present in the stem, then main idea will be rephrased as one of the answer choice. which is E.
