text 1\nduring the 1830s, samuel morse developed morse code, a new way to send messages.\nthe code was designed to be used on a telegraph. these machines could not send\n speech or written text, only electric pulses. therefore, morse assigned each letter in the\nalphabet a special series of pulses. people could press a button on the telegraph to\nsend the pulses. these were received as tapping sounds, which a person could then\n translate back into letters.\n\ntext 2\nmorse code was an extremely useful way to send messages over long distances.\nhowever, the original version of the code was difficult to use. it represented letters with\nvarious lengths of pulses, and it was hard to tell which length of pulse was being used.\nfor this reason, the code was updated to use only two types of pulses: short dots and\nlong dashes. these are easy to tell apart, and so the new morse code is easier to\nunderstand.\n\nwhich sentence best combines the main, or central, ideas of both texts?\nthe morse code system was named after its inventor, samuel morse, who also\ninvented the telegraph.\nalthough morse code was a clever way of sending messages, it fell out of use\nbecause it was too difficult to understand.\nmorse code was created for sending messages through a telegraph, and it\nwas updated to be easier to use.

Answer

Brief Explanations:

Text 1 focuses on Morse Code being developed for telegraph - based message - sending (using electric pulses). Text 2 highlights that the original code was difficult (due to various pulse lengths) and was updated (to short dots and long dashes for easier use). The third option combines these two main ideas: the creation of Morse Code for telegraph message - sending and its update for easier use. The first option is incorrect as Text 1 and 2 do not mention Samuel Morse inventing the telegraph. The second option is wrong because Text 2 does not say Morse code fell out of use; it only mentions an update.

Answer:

Morse Code was created for sending messages through a telegraph, and it was updated to be easier to use.
