Answer:
did this a few weeks ago u can use one of these:
#1-The invention of the telephone is an important device for facilitating human communication. The telephone was a very important invention of the nineteenth century which helped improve communications between people at a distance. The telephone provides a big change to existing methods of conversation at the time of its invention because jobs involved in conversation no longer needs to be in each other’s presence to communicate. Literacy was promoted through the use of the telephone due to the fact that people need to read and write in order to manufacture and operate telephone technologies. Today, the telephone is used as a one-way broadcasting medium for transmitting recorded messages.
or u can use this one-The lightbulb was the most significant invention. Other inventions such as the airplane and telephone have substitutes, whereas the lightbulb has one which isn’t very good. Without the lightbulb, people would have to use fire or sunlight as light sources… or electricity in some other way. Sunlight would be the most natural source of light, thus it will be the easiest to use, but fire can be moved to different places and can be controlled. Due to this, it is likely that sunlight would be used during the day, and torches and candles will be used in the night. This means that cars will have to find a way to use torches/candles for headlights, and structures will have to be made out of non-flammable substances. In conclusion, the lightbulb is the most useful and significant invention.
