What is the proper sequence for who influenced the development of our present-day alphabet?

The correct sequence for the influence on the development of our present-day alphabet starts with the Egyptians, followed by the Phoenicians, then the Greeks, and finally the Romans.

The Egyptians were among the first to develop a form of writing that included symbols representing sounds, laying the groundwork for later alphabetic systems. The Phoenicians built upon this by creating one of the first alphabets that represented sounds with a limited number of symbols, which significantly simplified writing and communication. The Greek alphabet then evolved from Phoenician concepts, adding vowels and adapting the symbols for their own language. Finally, the Romans further adapted the Greek alphabet to form the Latin alphabet, which is the basis of the modern alphabet used today.

This sequence highlights the historical progression of writing systems and how each civilization built upon the foundations laid by its predecessors. Other choices rearrange these influential cultures in a manner that does not accurately reflect the historical timeline and influence each had on the alphabet's development.
