Who in the Philippine Senate was the main proponent of the Chemical Engineering Law of 2004?

• A. Ramon Magsaysay
• B. Franklin Drilon
• C. Aquilino Pimentel
• D. Loren Legarda

Answer: (C)

The idea being tested is recognizing who leads a professional-regulation bill in the Senate and how that action shapes whether the bill becomes law. In this case, the senator who championed the Chemical Engineering Law of 2004 is Aquilino Pimentel. He introduced the measure and drove its passage, presenting the case that chemical engineers should be regulated to protect public safety and ensure competent practice. This kind of advocacy—sponsoring the bill, guiding it through committees, and galvanizing support among colleagues—is what earns the main proponent role in enacting professional laws. The other names are notable politicians, but they did not lead this particular initiative.
