A language model is being trained on a task to determine if one sentence is the direct follow-up to another. The training data consists of sentence pairs. 'Positive' pairs are two sentences that appear consecutively in a text. 'Negative' pairs are created by taking a sentence and pairing it with a random sentence from a different part of the text.

Consider the following short text:

1. The rocket launched at dawn.
2. It soared through the atmosphere.
3. The crowd watched in awe.
4. Mission control confirmed a successful liftoff.

Based on the data generation method described, which of the following is a correctly formed 'negative' training example?
