A schedule of three database transactions $T_1$, $T_2$, and $T_3$ is shown. $R_i(A)$ and $W_i(A)$ denote read and write of data item $A$ by transaction $T_i, i = 1,2,3$. The transaction $T_1$ aborts at the end. Which other transaction(s) will be required to be rolled back? $$R_1(X) \quad W_1(Y) \quad R_2(X) \quad R_2(Y) \quad R_3(Y) \quad ABORT(T_1)$$
