Improving Sentences-Confusing Question..Please help!

<p>The flier describing the details of the blood drive requested that we are in the hospital lobby promptly at 10 A.M.
(are in the hospital lobby) is underlined.</p>

<p>Correct answer choice:
be in the hospital lobby.</p>

<p>Can anyone explain the reasoning behind this and also, tell me the verb tense being used in the sentence?</p>

<p>Thanks :)</p>

<p>It is the case of subjunctive.</p>

<p>The Subjunctive is used after the following verbs:</p>

<p>to advise (that)
to ask (that)
to command (that)
to demand (that)
to desire (that)
to insist (that)
to propose (that)
to recommend (that)
to request (that)
to suggest (that)
to urge (that)</p>

<p>Examples:

Is it essential that we be there?
Don recommended that you join the committee.
Dr. Smith asked that Mark submit his research paper before the end of the month.
Donna requested Frank come to the party.
