Final answer:
Smith-Kline Beecham is using a synthetic production system to make Tums Plus by combining the ingredients to create the final antacid product.
Step-by-step explanation:
The production system Smith-Kline Beecham is using to make Tums Plus, which includes calcium carbonate, simethicone, corn syrup, and other ingredients, falls under the category of synthetic production.
This is because the ingredients are combined to produce a specific product with specific properties, rather than being extracted or analyzed.
For example, in the case of Tums Plus, the process involves the synthesis of all the ingredients together to create the final antacid product.
