A sentence's verb tense can be flawed in many different ways, so
it's less important to look for particular flaws than to isolate the
sentence's verbs and see whether they make sense together.
Know in advance that every verb in a particular sentence does not
need to have the same tense to be correct. Pay attention to shifts
in the direction of the sentence; don't look to see whether the
tenses are the same, but whether they make sense together.
