Question 1: A room has a light source that has a Color Rendering Index of 90.
What does this mean?
A. It is a measure of the brightness of the color of the objects in the room
B. The color of the objects in the room will be accurately produced
C. This is an industry standard cool white fluorescent lamp
D. The lamp is suitable for an area where color rendition is not important like a loading dock
Correct answer: B. The color of the objects in the room will be accurately produced
Color Rendering Index (CRI) is a measure of the ability of an artificial light source to accurately reveal the colors of the subject being lighted in comparison to the sun.

Question 2:
Refer to the network diagram.
What is the critical path?
A. 1-3-4-5
B. 1-5
C. 1-2-3-4-5
D. 1-2-3-5 - 1-2-3-5
Correct answer: A. 1-3-4-5
The critical path follows the greatest amount of time for all activities to be completed. Since the other tasks can be completed in less time, they are not “critical”.

Question 3: An ARE exam candidate is studying for their exams and comes across a concept called a smoke-proof enclosure.
Which building type uses smoke-proof enclosures?
A. Baseball stadium
B. Residential high-rise
C. Large commercial bakery
D. Atrium building
Correct answer: B. Residential high-rise
Smoke-proof enclosures are stair towers in high-rise buildings that are designed to give occupants a safe place to exit the building or wait for assistance during a fire or rescue event. The walls are constructed with 2-hour rated construction and the enclosures are pressurized to keep smoke out.

Question 4: A structure is designed to resist a load of 80,000 pounds. The actual anticipated load is 50,000 pounds.
What is the safety factor?
A. 0.6
B. 1.0
C. 1.6
D. 2.3
Correct answer: C. 1.6
The answer is 1.6. Having a safety factor means the structure has a margin of capacity beyond that which is required. The safety factor of a structure is the actual capacity divided by the required capacity.
80,000 / 50,000 = 1.6

Question 5: A path from a parking lot to a picnic shelter is 250 feet long. There is a 48 foot change in elevation.
What is the approximate average slope of the path?
A. 2%
B. 10%
C. 20%
D. 25%
Correct answer: C. 20%
Slope is rise over run. Slope (%) = [elevation gain (v) / horizontal distance (h)] x 100
48/250 = 0.192
0.192 x 100 = 19.2% or approximately 20%
Ref: Building Construction Illustrated (5th edition) 1.10
Hi @josemo, and welcome to our ARE Community!
I’m seeing the answer as 20% currently, are you saying it shouldn’t be C. 20%?
I can not find it now but it said 8%. sorry for the confusion.
