Question

anytime scaffolds are assembled or ______, a competent person must oversee the operation. select the best option. climbed disassembled photographed located

Explanation:

The sentence is about scaffold operations. "Assembled" means putting together, so the logical opposite or related operation that would also need oversight is taking apart, which is "disassembled". "Climbed" is about using the scaffold, "photographed" and "located" are unrelated to the assembly - disassembly context of scaffolds.

Answer:

B. disassembled (assuming the options are labeled as A. climbed, B. disassembled, C. photographed, D. located)
