Q1. As shown in Figure 1, there is a box that generates a single output in response to two
inputs. The input to this box is either “Agree” or “Disagree.” The output “Agree” is
generated only when both inputs are “Agree,” and in other cases the output “Disagree”
is generated. When three inputs are entered into two boxes as shown in Figure 2,
which of the following is the correct description concerning the output? Here, each
box of Figure 2 has the same function as the box of Figure 1.
a) The output “Agree” is generated at all times when one or more inputs are “Agree.”
b) The output “Agree” is generated at all times when two or more inputs are “Agree.”
c) The output “Disagree” is generated only when two or more inputs are “Disagree.”
d) The output “Agree” is generated only when all three inputs are “Agree.”
