we have a NAND, a NOR, and AND gate

For an unknown reason the output Q is all the time logic $0.$

Develop the truth table of the circuit and determine the simplest logic expression of the output Q$.(1$p$)$

List all possible reasons that might make the output Q be LOW for any binary combination at the input. $(1$p$)$Refer to the circuit above:
