\[\begin{aligned} a &\lt 0 \\ b &\gt 1 \\ -1 \lt c &\lt 1 \end{aligned}\]Tick the correct box for each statement. [4 marks]
| Always true | Sometimes true | Never true | |
|---|---|---|---|
| \(a^3 \lt 0\) | |||
| \(b \lt 10a^2\) | |||

| \(b - c \gt 1\) |

| Always true Sometimes true Never true Sometimes true | B4 | B1 for each correct answer |
Additional guidance
More than one box selected in a row is B0 for that row
Allow any unambiguous indication of a selection in a row
eg uses crosses instead of ticks
Ignore working seen and mark the boxes
