Which of the following was NOT listed as part of the apparatus used in the practical?

• A. Questionnaires
• B. Videos
• C. Debrief
• D. Stopwatch

Answer: (B)

The correct choice indicates that "Videos" were not part of the apparatus used in the practical. The term "apparatus" typically refers to the physical tools or instruments used during an experiment or study. In this context, questionnaires, debriefs, and stopwatches are all practical components that can be directly involved in data collection and participant interaction.

Questionnaires serve as a method for gathering standardized responses from participants, allowing researchers to quantify feelings, thoughts, or behaviors. A debrief is crucial in research ethics, ensuring that participants understand the study and its purposes after their participation. A stopwatch is often used to measure time intervals during tasks, which is critical in experiments where timing is essential.

In contrast, videos may not serve as a physical apparatus in a traditional sense but could be supplementary materials. Since they do not directly fall into the category of equipment for conducting an experiment, designating them as part of the apparatus would be inaccurate. Thus, the absence of "Videos" in the list aligns with the definition of the apparatus in the practical context.
