what were the items that greatly aided business transactions?

thresher
seed drill
telephone
reaper
transcontinental telegraph

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.
