A text-to-text model is being trained to simplify sentences. The model learns by being shown a single text string that contains a task prefix, the complex sentence, a separator, and the target simplified sentence. Given the complex sentence 'The legislative body is currently deliberating on the proposed amendments to the existing environmental regulations' and its simplified version 'The government is discussing changes to the environmental laws', construct the complete training sample as a single string. Use 'Simplify:' as the task prefix and '→' as the separator.
