nccer 00103 - introduction to hand tools 52min what does it mean when an object is plumb? perfectly horizontal parallel perfectly vertical

Explanation:

In construction and hand - tool related contexts (which can be associated with fields like Engineering in Natural Science or Construction Project Management in Social Science), the term "plumb" is used to describe an object that is perfectly vertical, aligned with the direction of gravity. A perfectly horizontal object is described as "level", and "parallel" means two or more objects run in the same direction and never meet, which is not the definition of plumb.

Answer:

C. perfectly vertical (assuming the options are labeled A, B, C as A. perfectly horizontal, B. parallel, C. perfectly vertical)
