Which outcome primarily motivated historical terrace construction alongside steep slopes?

💡 Explanation

Increased arable land availability was the primary motivator, facilitated by soil TERRACING. Terracing implemented stepped structures to create level surfaces ideal for agriculture, thus maximizing land use on sloped terrain, because arable lands were scarce, and this was a labor-intensive solution. This therefore provided platforms rather than increased sunlight.
