Explanation:
Superposition results in adding the two waves together. Constructive interference is when two waves superimpose and the resulting wave has a higher amplitude than the previous waves. Destructive interference is when two waves superimpose and cancel each other out, leading to a lower amplitude.
The correct answers are as follows:
1. MESOPOTAMIA: Ancient region of Southwest Asia between the Tigris and the Euphrates river. Mesopotamia means 'the land between the rivers'.

The Sumerians lived in the Mesopotamia region. Around 3500 BC, the Summerians invented a potter wheel, it was a heavy flat disk made of hardened clay.

Amorites were normads who usually made incursions into established kingdoms. The Amorities conquered the Fertile Crescent around 2000 BC.
5. BABYLONIANS: Founder of algebra and astronomy.
The Babylonians invented algebra and astronomy. Knowledge of Babylonian mathematics originated from some 400 clay tablets which were unearthed in the 1850s. Babylonian mathematics are writing in cuneiform scritpt; tablets are usually inscribed when the clay is moist and it is then baked hard in the oven or in the sun. Western Astronomy has its origin in Babylonian astronomy. Babylonian astronomers tracked the motion of planets across the night sky by using simple arithmetic.
