A ledgerAn organized record used to reconstruct events or changes.
Example: Compare dispatch with a later receipt. is an organized record of events or changes that people use to establish a history. Think of a shipment register: it records what someone says was dispatched or received.
In this course, every named organization and numerical case is hypothetical. Cedar Parts supplies components, Brook Freight carries them, and Lake Assembly receives them.
Their disagreement is about a receipt, not a cryptocurrency price. Begin with the business question before naming a technology. A shared record could help them work from the same accepted information, but it would not inspect the cartons for them.
Read the situation
Cedar records 12 cartons dispatched for shipment P17. Brook records 12 collected. Lake records 11 received, with one carton missing. Each keeps its own spreadsheet.
Write the disputed fact and one fact the three records already agree on in the problem section.
Reveal a completed response
The disputed fact is the quantity delivered to Lake. Cedar and Brook agree that 12 cartons entered transport; Lake reports receiving only 11.
The records concern different events. Twelve collected and eleven received can both be accurate if one carton was lost in transit; overwriting one number would conceal that possibility.
