Will a cyclist coast farther if the lamp connected to his generator is turned off? Explain.

I doubt it. Yes, the lamp is using energy. However, there are other factors: is the Lamp LED or light bubls. LED's use very little power. Air and road friction is probably a much greater factor in energy usage than the lamp, especially if it is LED. If the tires are poorly inflated (friction), I suspect in 100 trials, there would be no significant difference in coasting distance.
