Document 3 - Morse Code

Consider each of the following statements. Does the information in the three sources support the inference as stated?

Yes

No

The international distress call SOS is considered a prosign; that is, the usual three-unit space between letters is not present. (This means SOS is essentially like one letter.) Given this information, it would take nine units to spell SOS.

It takes at least 70 units to send the phrase “morse code” in Morse Code.

The maximum number of possible characters that could be found in the dichotomic search table is 64.
