It is popularly believed that a poem has whatever meaning is assigned to it by the reader. But objective evaluation of poetry is possible only if this popular belief is false; for the aesthetic value of a poem cannot be discussed unless it is possible for at least two readers to agree on the correct interpretation of the poem.
Which one of the following is an assumption required by the argument?
(A) Only if they find the same meaning in a poem can two people each
judge that it has aesthetic value. - WRONG. Not about whether poem has aesthetic value.
(B) If two readers agree about the meaning of a given poem, that
ensures that an objective evaluation of the poem can be made. - WRONG. Not about what degree of agree between people leads to objective evaluation. Takes the non core aspect of the passage and tries to make it core.
(C) Discussion of a poem is possible
only if it is false that a poem has whatever meaning is assigned to it by the reader. - WRONG. Again whether it is false or not depending upon meaning assigned to the poem is not core of the argument.
(D) A given poem can be objectively evaluated only if the poem’s aesthetic value can be discussed. - CORRECT. The independent sentence after semicolon in the last sentence is the reasoning given by the author. Conclusion is first independent sentence. How two are related is what this option helps us with to understand. If aesthetic value can't be discussed, one can't reach an objective evaluation of the poem, eventually leading to popular belief being wrong.
(E) Aesthetic evaluation of literature is
best accomplished through discussion by more than two readers. - WRONG. Irrelevant. How evaluation is accomplished is not the core of the argument.
Answer D.
