a1e2 ¬Mv¬P
¬ e1a2 M∧P

(Negation of "Someone trusts and admires everyone.")
[013]
e1a2 S∧M
Someone loves and trusts everyone.
[113]
(a1e2 ¬Mv¬P) ∧ (e1a2 S∧M)
e12 S∧¬P
Someone has someone whom they love, but whom they don't admire.
[171]
Rather boring conclusions
[062] and [060] are also conclusions, just like [171], but they follow from the second premise alone:
e1a2 S ∧ M
⇒
{\displaystyle \Rightarrow }
e1a2 S
⇒
{\displaystyle \Rightarrow }
e1a2 S ∨
whatever
e1a2 S
Someone loves everyone.
e1a2 S∨¬P
¬ a1e2 ¬S∧P
Someone loves or doesn't admire everyone.
(Negation of "Everyone has someone whom they don't love, but admire.")
[062]
e1a2 S∨P
¬ a1e2 ¬S∧¬P
Someone loves or admires everyone.
(Negation of "Everyone has someone whom they neither love nor admire.")
[060]
