Which features of Mycenaean civilization came from the Minoans?

their alphabet and system of writing
their use of an army to conquer nearby people
their building of settlements on the Greek mainland
their religious beliefs and practices

Their use of an army to conquer nearby people is a feature of Mycenaean civilization that came from the Minoans. However, the other three features mentioned - their alphabet and system of writing, their building of settlements on the Greek mainland, and their religious beliefs and practices - were not directly inherited from the Minoans. Rather, the Mycenaeans developed their own writing system, known as Linear B, which was different from the Minoan Linear A script. The building of settlements on the Greek mainland was a characteristic of Mycenaean civilization, and their religious beliefs and practices were shaped by their own traditions and influences from other cultures in the Mediterranean region.
