Question

1. a new opening has been created in this masonry wall. what is the main thing you see? 1 image of a masonry wall with red arrows pointing to areas the wood beam is undersized the caulking is ineffective there is no lintel supporting the brickwork the electrical wiring on the left should be in rigid conduit the metal straps on the wood should be corrosion resistan

Explanation:

In masonry wall construction, a lintel is typically used to support brickwork above openings. The image shows a masonry wall with an opening where the brickwork above lacks a lintel (a structural element to support the bricks). The other options relate to beam size, caulking effectiveness, wiring conduit, or strap corrosion, which are not the main structural issue here. The key structural concern for the masonry wall opening is the absence of a lintel to support the brickwork.

Answer:

C. There is no lintel supporting the brickwork
