A researcher is fine-tuning a model for a question-answering task. The model processes a question and a context paragraph to predict the start and end positions of the answer within the paragraph. After training, the researcher observes a specific performance issue: the model consistently identifies the correct end token of the answer span, but frequently selects an incorrect start token. Based on the typical architecture for this task where separate predictions are made for the start and end points, which component is the most likely source of this specific error pattern?

A model is designed to extract a specific span of text (the answer) from a larger context paragraph based on a given question. Arrange the following steps in the correct logical order that describes how this model processes the information to identify the answer.
