Consider the following database schedule with two transactions, $T_1$ and $T_2$.

$S= r_{2}\left(X\right); r_{1}\left(X\right); r_{2} \left(Y\right); w_{1} \left(X\right); r_{1} \left(Y\right); w_{2} \left(X\right); a_{1}; a_{2}$

where $r_i(Z)$ denotes a read operation by transaction $T_i$ on a variable $Z$, $w_i(Z)$ denotes a write operation by $T_i$ on a variable $Z$ and ai denotes an abort by transaction $T_i$ .

Which one of the following statements about the above schedule is TRUE?
