Answer 2

The correct option that gives a proper logic for the argument that "If X, then Y. If Y, then Z. Y is true" is given by;

Option B; X is unknown, Z is true

• This question is based on the principles of logic. Logic helps us distinguish between valid and invalid arguments.

• Now, the argument here is that;

If X, then Y. If Y, then Z. Y is true.

• Now, from this argument, we can see that Y depends on X and then Z depends on Y.

• Now, we are told that Y is true. Since Z depends on Y as seen that If Y, then Z, we can say that Z is also true.

However, we can't say anything about X as X is unknown.
