T5 Sample Format
The T5 model utilizes a unified text-to-text format for all training samples, structured as . Within this structure, the source text provides the system with both a task description or instruction and the specific input data. The target text represents the expected response to the input task. By maintaining this consistent format, the model is able to frame and process many different problems as the same text-to-text task.

Critique of the T5 Text-to-Text Approach
A developer is using a unified model that frames all natural language processing problems as a text-to-text task. The goal is to build a feature that extracts the main subjects from a sentence. Given the input text 'Instruction: Identify the subjects. Text: The cat and the dog played in the yard.', which of the following outputs best demonstrates the model's core operational principle?
A key principle of a unified text-to-text model is its ability to handle diverse natural language processing tasks by framing them as a transformation from an input text to an output text. Match each traditional NLP task with the most appropriate input/output text pair that represents how this type of model would process it.

T5 Sample Format
A developer wants to frame a sentiment analysis task for a text-processing system. The goal is to classify the sentence 'The movie was fantastic!' as 'positive'. Based on the standard 'Source Text → Target Text' structure, which of the following options correctly formats this task?

Formula for Input Embedding Composition
A researcher wants to train a model to perform a new task: converting a sentence from passive voice to active voice. Given the passive input sentence 'The cake was eaten by the dog' and the desired active output 'The dog ate the cake', which of the following training samples is correctly structured according to the unified, prefix-based text-to-text format?
Critiquing a Text-to-Text Training Sample
A single text-to-text model is being trained on a dataset containing samples for four different tasks. Each sample's input begins with a prefix that instructs the model on what to do. Match each input sample (Source Text) with the most likely task it is intended for.
