I knocked on the door. No one answered, so I opened it.

As the door swung open, I saw a round table filled with high-ranking Nazis. Their caps were on the table, and in the middle of the table was a radio. The radio was playing an English broadcast. Right away, I recognized the BBC. All their eyes burned into me. I realized that I had accidentally witnessed them committing a crime of treason, for which the penalty was death. —Anne Frank Remembered, Miep Gies

What is one way Gies builds suspense in this passage?

by using “I” throughout the narration to make it feel personal
by explaining how she survived the situation despite the danger
by telling of a dangerous situation in which she accidentally learns information
by showing that she is sure she will die because of how angry the Nazis look
