---------------------------------
if anything BEFORE the verb CAN BE the subject, then that thing will be the subject.

this advice mostly applies to sentences like this one: "A is/are B".
specifically:
in the sentence "noun1 is/are noun2", noun1 is the subject.
in the sentence "noun2 is/are noun1", noun2 is the subject.

for instance:
the hardest part of the test was the last three questions --> "hardest part" is the subject.
the last three questions were the hardest part of the test --> "last three questions" is the subject.

you only have a backward construction (verb before subject) if NOTHING in FRONT of the verb is eligible to be the subject.

on the table are two cell phones
--> "on the table " is a prep. phrase and therefore can't be the subject, so this is a backward construction. "two cell phones" is the subject.

harder than anything else on the test were the last three questions
--> here "harder than anything on the test" contains no eligible subjects, so this is backward construction; "the last three questions" is the subject.
