The flower was not invented to please us. It flaunted its petals and spread its perfume to attract an insect. The insect carries the pollen from flower to flower so that pollen is not carried away by wind and thus not wasted. What we call a flower’s beauty is merely a by-product and a human invention. The perfume is not there to please us, it pleases us because it is there, and we have been conditioned to it.

Correct Option (4)

Option 4 is correct because neither of the assumptions is valid according to the passage.

• The passage emphasizes the evolutionary utility of flowers, specifically their role in attracting insects for pollination, rather than portraying them as creations of "Nature's luxury." The author explicitly states that a flower's beauty is a "by-product and a human invention," which contradicts the idea of luxury as an inherent purpose. Therefore, Assumption 1 is invalid.
• The passage clearly outlines the biological usefulness of flowers in facilitating pollination ("The insect carries the pollen from flower to flower so that pollen is not carried away by wind and thus not wasted."). This directly refutes the claim that the author does not believe in the usefulness of flowers except for their aesthetic value. Therefore, Assumption 2 is invalid.

Incorrect Options:

• Option 1 is incorrect because Assumption 1 is invalid. The passage does not support the idea that flowers are creations of "Nature's luxury"; instead, it highlights their functional purpose.
• Option 2 is incorrect because Assumption 2 is invalid. The passage explicitly details the ecological utility of flowers in pollination, which goes beyond mere aesthetic beauty.
• Option 3 is incorrect because both Assumption 1 and Assumption 2 are invalid based on the explanations provided.
