Which term refers to the study or discussion of machinery and mechanical systems?

• A. Metro
• B. Makinismo
• C. Tulog-mantika
• D. Taingang-kawali

Answer: (B)

The concept being tested is naming a field that focuses on machines and how their parts and systems work. The term that fits this idea is makinismo, which combines makina (machine) with the suffix -ismo that often marks a field of study or practice. This makes it the best fit for describing discussion or study of machinery and mechanical systems. The other options refer to unrelated ideas—a metro is a transit system, tulog-mantika is a Filipino phrase about sleep or laziness, and taingang-kawali means a tin ear—so they don’t match the focus on machinery.
