Question

based on how it is used in this part of the selection, what does the word code most closely mean?
a a book of laws
b a group of people
c a way of fighting
d a secret language
julius caesar was a powerful roman ruler. he had many generals in his army. he needed a safe way to send messages to them. so he made a code. his code used the letters of the alphabet. a letter was not used as itself. instead, if stood for another letter that was three places away. for example, instead of using an a, he used a d. a b became an e. so, the message attack would read as dwwdfn.

Explanation:

The text describes Caesar creating a "code" by changing letters in the alphabet. This is similar to a secret language. A book of laws (A) is not relevant as there's no mention of laws. A group of people (B) is incorrect as the focus is on letter - changing. A way of fighting (C) is not indicated. The description aligns with a secret language (D).

Answer:

D. a secret language
