From statements (Second + Third + First) conclusion (a) follows.
Again, from (Second + Third + Fourth) conclusion (b) follows
From statements (First + Second), the possibility in (c) exists. Hence, (c) follows.
From statements (Third + Fourth), conclusion (e) follows. Again, All motels are apartments (A) + All apartments are inns (A) = A + A = A = All motels are inns. Hence, (d) does not follow.
Hence, only conclusion (d) does not follow.
From statements (Second + Third + First) conclusion (a) follows.
Again, from (Second + Third + Fourth) conclusion (b) follows
From statements (First + Second), the possibility in (c) exists. Hence, (c) follows.
From statements (Third + Fourth), conclusion (e) follows. Again, All motels are apartments (A) + All apartments are inns (A) = A + A = A = All motels are inns. Hence, (d) does not follow.
Hence, only conclusion (d) does not follow.
