The correct answer is c. Photo-controls are typically used to control the turn on and turn off of individual luminaires or groups of luminaires. Photo-controls, also known as photocells, are devices that sense light levels and automatically turn the lights on or off based on the ambient light level.
They are commonly used in outdoor lighting applications such as streetlights, parking lots, and building facades. Time clocks, on the other hand, are used to control the timing of when lights turn on and off. They are often used in indoor lighting applications such as offices, schools, and commercial buildings. Time clocks can be set to turn lights on and off at specific times, or they can be programmed to vary the on/off times based on the day of the week or season. Breakers are electrical safety devices that are designed to protect electrical circuits from overloading and short circuits. They are not typically used to control the turn on and turn off of luminaires. Remote switches are switches that are located away from the light fixture itself. They can be wired or wireless and are used to turn lights on and off from a distance. Remote switches are often used in situations where it is not practical or safe to access the light fixture directly, such as in high-ceilinged rooms or hazardous locations.

true or false Semantic ambiguity most often results from syntactic ambiguity
False. Semantic ambiguity refers to cases where a word or phrase has multiple meanings and it's unclear which meaning is intended
in a particular context, while syntactic ambiguity refers to cases where the structure of a sentence allows for multiple possible interpretations. While these two types of ambiguity can co-occur in a sentence, they are distinct phenomena that arise from different sources. For example, a sentence like "I saw her duck" is semantically ambiguous because the word "duck" could refer to either a bird or a motion, while it is syntactically ambiguous because it is unclear whether "her" is the subject or object of the verb "saw".

Fusion is the process of using heat and pressure to connect two parts of pipe together. There is no need to clean piping that is going to be fused because there is no solvent used to make the fusion.
The given statement "Fusion is the process of using heat and pressure to connect two parts of pipe together. There is no need to clean piping that is going to be fused because there is no solvent used to make the fusion" is false because the pipe surfaces need to be thoroughly cleaned before fusion to ensure a strong bond.
Fusion involves using heat to melt the surfaces of the pipes to be joined, and then pressure is applied to fuse them together. Any contaminants, such as dirt, grease, or oil, can interfere with the fusion process and weaken the bond between the pipes. Therefore, cleaning the pipes is essential to ensure a reliable and long-lasting joint.
In summary, even though no solvent is used in fusion, it is still necessary to clean the piping surfaces to ensure a successful fusion process.

Galvanized wire rope is approximately 10% higher in strength than bright wire rope. Select one: a. True b. False
The statement is false. Galvanized wire rope is not approximately 10% higher in strength than bright wire rope. The strength of wire rope depends on various factors such as the material composition, construction, and manufacturing process, rather than solely on whether it is galvanized or bright.
Galvanized wire rope refers to a type of wire rope that has been coated with a layer of zinc to enhance its corrosion resistance. This coating helps protect the wire rope from rust and can extend its lifespan in certain environments. However, the zinc coating does not significantly impact the tensile strength or breaking strength of the wire rope. The strength of wire rope is typically determined by factors such as the diameter of the wires, the number of strands, and the construction (e.g., 6x19, 7x19, etc.). Therefore, it is not accurate to state that galvanized wire rope is consistently 10% higher in strength than bright wire rope. The strength comparison between different wire ropes needs to consider their specific construction and specifications.
