Final answer:
When there is one solid yellow line on the far side and one dotted yellow line closest to you on the road, you should not pass any vehicles and wait until the solid yellow line changes .
Step-by-step explanation:
When you see one solid yellow line on the far side and one dotted yellow line closest to you on the road, it means that you are in a situation where passing is not allowed on your side of the road, but passing is allowed on the other side.
In this scenario, you should refrain from overtaking any vehicles and maintain your position behind the other vehicles. Wait until the solid yellow line changes to a broken line before considering passing another vehicle.
The correct answer is option 17 regarding the observation of dashed streaks caused by fluorescent lights when viewed from a moving train.
When you're inside a moving train and you observe nearby fluorescent lights, they may appear as dashed streaks due to an effect known as the stroboscopic effect.
This phenomenon occurs because fluorescent lights do not emit a constant light; instead, they flicker at a rapid rate that is generally imperceptible to the human eye.
However, when in motion, each flicker can be registered as a separate streak because the frame of reference (the train and the observer) is moving relative to the light source.
This is similar to the way a strobe light creates a series of frozen images at a dance party. Your own motion distorts the continuous light into dashes because you move some distance between each flicker of the light, capturing a different 'frame' or position of the light source each time.
