Question: Show each of these specifications using predicates, logical connectives and quantifiers, if necessary. You must invent the predicates!

a) At least one console must be accessible during every fault condition

b) The e-mail address of every user can be retrieved whenever the archive contains at least one message sent by every user on the system.

c) For every security breach there is at least one mechanism that can detect that breach if and only if there is a process that has not been compromised.

d) There are at least two paths connecting every two distinct endpoints on the network.

e) No one knows the password of every user on the system except for the system administrator, who knows all passwords.

You have to satisfy the requirements specific in the instruction.
