The correct answer is: A. Bicycle : Wheel
A candle is a small, solid block of wax with a wick embedded in it. When the wick is lit, the heat from the flame melts the wax near the wick, and the liquid wax is drawn up the wick by capillary action. The heat of the flame vaporizes the liquid wax, and the vaporized wax combines with oxygen in the air to produce a flame. The flame heats the wick, and the cycle repeats.
A bicycle is a human-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
The relationship between “candle” and “wick” is that the wick is essential for the candle to function. The wick provides a surface for the wax to melt and vaporize, and it also provides a path for the vaporized wax to travel to the flame. Without the wick, the candle would not be able to produce a flame.
The relationship between “bicycle” and “wheel” is similar. The wheels are essential for the bicycle to function. The wheels provide a surface for the bicycle to roll on, and they also provide a way for the rider to propel the bicycle forward. Without the wheels, the bicycle would not be able to move.
The other options do not have the same relationship as the original pair of words.
- Option B: Oven : Fire. The oven is a device that cooks food by using heat. The fire is not essential for the oven to function. The oven can be heated by electricity, gas, or other sources of heat.
- Option C: Hammer : Nail. The hammer is a tool that is used to drive nails into wood. The nail is not essential for the hammer to function. The hammer can be used to drive other objects into wood, such as screws or bolts.
- Option D: Light : Bulb. The light is a source of illumination. The bulb is not essential for the light to function. The light can be produced by other sources, such as a candle or a fire.
