The answer is E: All the above.

Explanation for each option:

A. Excavation activities: Excavation involves digging into the ground, which can potentially disturb underground electrical systems if they are present.

B. Earth drillers: Earth drilling involves penetrating the ground, which can also come into contact with underground electrical systems.

C. Jack hammering: Jack hammering involves breaking up the ground or pavement, which can inadvertently strike underground electrical systems.

D. Fence Installation: Installing fences often requires digging post holes, which can also risk contact with underground electrical systems.

Since all these activities involve some form of ground penetration or disturbance, they all pose a risk of contacting underground energized electrical systems. Therefore, the correct answer is E: All the above.

A facilities supervisor at a sports stadium wants to rate the condition of the seats at the stadium. Which of the following best describes a convenience sample of seats? The supervisor uses a computer program to draw 56 seats at random and selects these seats. Every set of 56 seats is equally likely to be drawn by the computer program. All of the seats in the VIP section are easily accessible. So, the supervisor selects the 56 seats in this section. The supervisor forms groups of 8 seats based on the sections the seats are in. Then, she selects all of the seats in 7 randomly chosen groups.
