Two from the bank, answered.

Real items, with the answer marked and the reason written out — the same format as all 252.

Core Trades Remodeling

A bathroom toilet's centerline is 17 inches from the left wall and 13 inches from the tub on the right. What does the handout say?

  1. AThe right side is too tight; 15 inchesCorrect
  2. BThe left side is too tight; 18 inches is required
  3. CBoth sides pass because the total is 30 inches
  4. DThe toilet must be 24 inches from each side

Why: The handout requires 15 inches from the centerline to each side, so 13 inches fails even though the two sides total 30. Eighteen inches is not the figure, and 24 inches is the clear space in front.City of Rancho Cucamonga handout BSF-0031 (CPC 402.5 as cited)

Finish Trades Remodeling

In one cabinet guide, what height above the floor's high point does the first level line mark?

  1. A34-1/2 inches, the bottom of the wall cabinets
  2. B54 inches, the top of the base cabinets
  3. C84 inches, the top of the base cabinets
  4. D34-1/2 inches, the top of the base cabinetsCorrect

Why: The base level line is drawn 34-1/2 inches above the high point and marks the top of the base cabinets. Fifty-four inches is the wall cabinet line, and 84 inches is the top line for 30-inch wall cabinets.Manufacturer installation guide (cabinets)
