Suppose one of your employees reports to you that ‘we can keep the account with Widgetco only if we do not deal with Acme,' and that another one tells you ‘either we don't keep the account with Widgetco or we do not deal with Acme.' Are your two employees saying something equivalent or are they giving you different advice?
a. They are saying something equivalent.
b. They are giving different advice.
c. The employees are just being negative. There's always a way.
d. It is impossible to say because of a linguistic anamorphism in the pair of statements.
