So the form of the simple future is "will/shall/be going to/be to/ be about to + v (root form)n .T: There are signal words “Right now” in sentence 3, so the tense is present continuous. Its form is "is/am/are + present participle” . The right answer is "is urging” .

So the tense in sentence 4 is past continuous tense.
