Please help me how to solve this question. Thank you very much

Chemistry

The 2′,3′-cyclic phosphodiester that is formed when RNA is cleaved, forms a mixture of nucleotide 2′- and 3′-phosphates when it reacts with water. Propose a mechanism for this reaction.

Can u help pls with this aldol rxn thank u
