What has been the significance of a written alphabet to past societies?

Literacy happened in Egypt, more than a millennium after writing was born.

The first formal alphabet emerged around 2000 BC. C. to represent the language of the Semitic workers in Egypt, and it was conceived from the alphabetic principles contained in the Egyptian hieroglyphs. Most of the world's current alphabets either descend directly from this root, for example Greek and Latin alphabets, or were inspired by its design.

There were different alphabets, Greeks, Romans, peninsular and Greeks

Explanation:

As soon as literacy emerged, it was considered to be a means of communication or codes by which it sought to transmit something.

Some considered it an ordered system of graphic signs that was used in the writing of some languages and that was based on the more or less approximate correspondence between these signs and the phonemes they represented.

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.
