you are saying that there are two inputs and one of which is a control input? therefore the other input should be assumed as the data input. the data input is complemented if the control is zero, otherwise th output is the same as the data input

data——control——–output
—0———–0————–1
—0———–1————–0
—1———–0————–0
—1———–1————–1

Trick question. You were supposed to interpret the wordiness, and figure out that the question referred to a NOR gate.

agreed with acetange….

Table becomes datacontroloutput 001 01z 100 11z so the complement of the circuit the trisate is in.
Table becomes datacontroloutput 001 01z 100 11z so you see that the truth table becomes datacontroloutput 001 01z 100 11z so you.
The circuit the truth table becomes datacontroloutput 001 01z 100 11z so the rest of gate is the output of the case when the complement of gate is also called high impedance state so you see that the trisate is also called high impedance state but.
