Based on the sequence of events in the excerpt, which
sentence best states a cause-and-effect relationship?
Read the excerpt from "The Telephone: A Truer Tale."
The year was 1849, and Antonio Meucci, a man trained
in engineering, was experimenting with electricity. He
and a doctor were trying to determine if electric shock
could be used to cure illnesses. One day, when he
turned on the switches to treat a patient in another
room, he heard the patient yelp. However, the voice
had not come from the next room-it had come from
the copper wire that ran between them!
Following that fateful day, Meucci left his medical
experiments behind. Instead, he set a goal to develop
that talking wire into a machine he called a "talking
telegraph." After six years of trials and tests, he was
able to build a working model. Meucci found it to be a
useful device almost immediately.
O Because Antonio Meucci was a trained engineer, he
was able to invent a "talking telegraph."
Because electricity was used to cure sickness,
Antonio Meucci invented the "talking telegraph."
O Because the device was so useful, Antonio Meucci
invented the "talking telegraph."
O Because he heard a patient's yelp through a copper
wire, Antonio Meucci invented the talking telegraph."
