Read the passage about the health risks of single-load liquid laundry packets.

These packets are filled with concentrated, toxic chemicals. A 7-month-old in Florida died from swallowing the soap. Several soap and detergent companies are conducting studies to address these safety concerns; they want to reduce toxicity and to make the packets look less like candy. The U.S. Consumer Product Safety Commission (CPSC) is also performing studies to build more safety into these products.

Why would the CPSC perform studies when other soap and detergent companies have already conducted research on the same products?

The CPSC is the only organization that can test the safety of soaps and detergents.
Studies conducted by any company that benefits financially are considered unreliable.
Studies performed by the CPSC give reliability to the results of improved safety obtained by each soap company.
Tests performed by the CPSC follow established scientific methods, but those performed by soap companies do not.
