Explanation:

The text states that the new verse forms and conceptual framework (specifically the new conceptual framework of a revenge tragedy) allow for the portrayal of powerful emotions, which leads to more passionate performances. The play The Spanish Tragedy and Tamburlaine the Great are examples of works that use these new elements. The collaboration of Kyd and Marlowe is not mentioned as the cause. The key is the new verse forms and conceptual framework as they enable the expression of passion.

the new verse forms and conceptual framework
