The origination of modernism and te avant-garde are examples of how Latin American poetry is more critical or irreverent in its attitute toward language. But the overall purpose of the paragraph isn’t about modernism or the avant-garde. Examples are always in service of a broader point; the purpose of an example is never going to be within the example itself.

This best captures the purpose of P2. The author presents examples of how Latin American poetry is more critical and irreverent about language, whereas Spanish poetry uses language in less radical or experimental ways.

The author never indicates that Latin American poetry isn’t well received in Spain. Spanish poets may have a different attitude about language and are reluctant to use language in the ways Latin American poets do, but this doesn’t imply that Latin American poetry isn’t received well in Spain. In any case, the purpose of the paragraph is to show a difference between Latin American poetry and Spanish poetry.

The purpose of the paragraph is to show a difference between Latin American poetry and Spanish poetry. (D) is too focused on the impact of modernism and the avant-garde on Castilian Spanish. But modernism and avant-garde are used as examples to show the attitude of Latin American poetry toward language.

The point about romanticization is presented in the last paragraph, not in P2.
