Consider the production $\mathit{A}\to \mathit{P}\mathit{Q}$ and $\mathit{A}\to \mathit{X}\mathit{Y}$. Each of the five non-terminal $\mathit{A},\mathit{P},\mathit{Q},\mathit{X}$, and $\mathit{Y}$ has two attributes: $\mathit{s}$ is a synthesized attribute, and $\mathit{i}$ is an inherited attribute. Consider the following rules.
Rule 1: P.i = A.i + 2, Q.i = P.i + A.i, and A.s = P.s + Q.s
Rule 2: X.i = A.i + Y.s and Y.i = X.s + A.i
Which one of the following is TRUE?
