To determine the tone of a passage, it's important to consider the overall feeling or atmosphere that the author is trying to convey. In this case, we can analyze the passage to identify the word that best describes the tone.

The passage describes a situation where the sound of a doorbell interrupts the protagonist and they find a strange object waiting outside. The mention of the truck disappearing into the darkness adds an element of mystery to the scene. However, the description of the protagonist taking a deep breath, opening the door, and stepping out into the heavy summer air suggests a feeling of anticipation rather than fear or suspense.

Based on this analysis, the best word to describe the tone of the passage is "Mysterious" because it conveys a sense of intrigue or curiosity about the events taking place. Therefore, the correct answer is 1. Mysterious.
