The trans-Atlantic telegraph joined England and the United States by wire.

a. True

b. False

True because america and europe needed to communicate in the 19th century

Strange as it may seem, that's true.

In 1858, ships carrying enormous rolls of cable finished laying

a cable under the sea, across the north Atlantic between the US

and England, making it possible for the first time to communicate

between North America and Europe faster than ships could make

the crossing.

That was only 20 years after the telegraph was first demonstrated

in New Jersey, through 2 miles of wire.

At the time the trans-Atlantic cable was completed, telegraph was

the only means of long-distance communication in existence.

None of these things had been invented yet:

- - telephone

- - radio

- - TV

- - sound recording

- - loudspeakers

- - ear buds

- - cars

- - airplanes

- - satellites.
