Correct answer: Upload a CSV file with only the new rows of data.
Why this is the answer
When updating a dataset created by uploading a CSV file to Google Cloud, you should upload a new CSV file containing only the new rows of data. This method is efficient as it appends the new information to the existing dataset without overwriting or duplicating unchanged records. Uploading a CSV with all original and additional data would create duplicate entries for existing records. The refresh fields icon in the data source updates the schema, not the underlying data. Manually editing data in a Data Studio report is not possible; Data Studio is a visualization tool, not a data manipulation tool for source data.
