Question

raj is playing a video game based on crafting ingredients to create a variety of high - technology appliances. what would be a sensible middle step between mining for silicon sand and creating semiconductors?
producing ingots
mixing saline solutions
molding bricks
crushing chalk

Explanation:

Silicon sand is mined. To create semiconductors, silicon ingots are an intermediate step. Silicon ingots are made from purified silicon (which can be derived from silicon sand through processes like reduction). Saline solutions (salt - water mixtures), bricks (clay - based), and chalk (calcium carbonate) have no relation to the semiconductor - making process from silicon sand.

Answer:

producing ingots
