Answer and Explanation:
The suspense is caused by the unpredictability within the narrative, which is established in such a way that the reader, as well as the characters and even the narrator, cannot predict the facts that occurred during the history of that point forward. This causes confusion, anxiety and consequently suspense. Proof of this can be seen in the phrase "Big Things Come in Small Packages" which presents a totally unexpected and unpredictable situation, since nobody expects a small package to contain something big, which we also don't know what it is, but which can be wonderful or terrible.
