BERT Input Format for Sentence Pairs
When handling sentence pairs, BERT processes them as a unified sequence. This sequence begins with a [CLS] token, followed by the first sentence (denoted as ), a separator token [SEP], the second sentence (), and a concluding [SEP] token. As established in the original BERT paper, the [SEP] token explicitly marks the boundary between the two sentences. This general input representation is formally expressed as the sequence: [CLS] SentA [SEP] SentB [SEP].

Next Sentence Prediction (NSP)
A language representation model is designed with the flexibility to process either a single piece of text or a pair of texts as its input, allowing it to be adapted for a wide variety of tasks. Which of the following tasks would most directly benefit from the model's ability to process a pair of texts?

Choosing Input Formats for Language Tasks
A language model is being used for four different tasks. Three of these tasks are best addressed by providing the model with a pair of texts to analyze their relationship. One task, however, only requires a single text input. Which task is the outlier that would be handled using a single text input?

An NLP model is tasked with evaluating the following pair of sentences:
Premise: 'The athlete won the gold medal after years of dedicated training.' Hypothesis: 'The athlete is successful.'
The model must determine if the hypothesis logically follows from the premise. Which specific type of text-pair classification problem does this scenario best exemplify?
