Answer:
A. Poems should be studied in many ways.
Explanation:
In his poem "Introduction to Poetry", Billy Collins emphasizes the need for patience and open-mindedness in reading or trying to understand poetry. In his opinion, he wants us to have an open mind and be free from any pre-notions when approaching poetry.
In the given lines, he states how a poem should be "hold up to the light/ like a color slide/ or press an ear against its hive". This means that like things that are put up to the light to be better understood and seen, poems should also be given the open-minded treatment with no pre-judgments. Thus, the central idea of the lines is that poems/ poetry should be studied and approached in many ways.
