Which of the following trades is included in Entrance Exam 4?

The Gas Utility Operator trade is included in Entrance Exam 4 because it focuses on the skills and knowledge specific to the operation and maintenance of gas distribution systems. This encompasses various critical areas such as safety protocols, the understanding of gas appliances, and regulation compliance. The inclusion of this trade in the exam acknowledges its unique requirements and the specialized training needed to work safely and effectively in this field.

On the other hand, while trades like Electrician, Carpenter, and Welder are essential and well-recognized fields, they are not part of Entrance Exam 4's structure or focus. Each of these trades has its own training and assessment pathways that are distinct from those required for Gas Utility Operators. Thus, recognizing Gas Utility Operator as a key trade for the exam highlights the industry’s need for skilled professionals in the area of gas utility management.
