Source Definitions

Which option presents the correct New York State information about Source Definitions?

• Time-sensitive claims about population, employment, agriculture, and GDP should include date, period, source agency, and whether values are estimates, counts, preliminary data, or revised data.
• A source bank should separate factual propositions from future quiz wording so one verified fact can support multiple pedagogically distinct question forms without duplicating meaning.
• The Hudson-Mohawk corridor is a classic example of how topography can create durable transport corridors that shape later infrastructure investment.
• Primary-source preference does not eliminate the need to understand definitions, because Census, BEA, BLS, USDA, and state agencies measure different concepts.
