A temporary opening in which something, such as a pipe or box culvert, is placed and then covered is a ________.

• A. Trench
• B. Pit
• C. Bore
• D. Shaft

Answer: (A)

A long, narrow open cut used to install utilities or culverts and then cover back up is called a trench. This shape and purpose fit how trenches are used in earthmoving: you dig a shallow, elongated space just wide enough to place a pipe or box culvert, lay the piece in, and then backfill to restore the surface. The other terms describe different geometries or methods: a pit is a broader, often deeper hole; a bore is a drilled hole through material; a shaft is a vertical passage. So, the term that matches a temporary opening for laying piping and then covering is trench.
