The correct answers are "reaper", "telephone", and "transcontinental telegraph".

  • Since its commercial introduction in 1830, the telegraph made it possible for businesses to close deals in a matter of days, as messages would be sent across the sea between continents.
  • The time frame for closing business deals would be further reduced with the introduction of the telephone in 1876, which would make it possible for business representants to engage in "live" negotiations, regardless of their location.
  • Since its creation in 2006, "Reaper" made it possible to manage audio files with ease. This led to the introduction of "audio contracts", which let businesses close deals with customers by phone instead of them going to their sites.

Answer:

  Telephone and transcontinental telegraph.

Explanation:

  The other options are items that aided the agricultural industry.

  Either of the items selected aid the business transactions because they allow the possibility of communication between people that lived at a long distance from each other. They also made the transactions faster as both systems connected long distances almost immediately.

  In the case of the transcontinental telegraph, it served as the only method of near-instantaneous communication between the east and the west of the United States during the 1860s. Before that, all communications were made by post mail and the travel for one coast to the other last 110 days average.

  I hope this answer helps you.
