Question 1: Select all that apply

In plan-space (partial-order) planning, a causal link $(a_2, P, a_3)$ records that action $a_2$ produces the condition $P$ for action $a_3$ . Which conditions are required for another action $a_1$ in the partial plan to be a threat to this link? Select all that apply.

$a_1$ has an effect $\lnot Q$ where $Q$ can be unified with $P$ 1
$a_1$ can be ordered after $a_2$ 2
$a_1$ can be ordered before $a_3$ 3
$a_1$ also produces $P$ 4
$a_1$ must already be ordered before $a_2$ 5
