Find the set of possible values of \(x\).
Tick ( \(\checkmark\) ) one box.
$$\begin{aligned}
& \{ x : x < 1 \} \cup \{ x : 2 < x < a \} \\
& \{ x : 1 < x < 2 \} \cup \{ x : x > a \} \\
& \{ x : x < - a \} \cup \{ x : - 2 < x < - 1 \} \\
& \{ x : - a < x < - 2 \} \cup \{ x : x > - 1 \}
\end{aligned}$$
