explanation: "bicycle" is a kind of "eco-friendly" "travel". "vegetable" is a type of "food". "vegetable" and "health" correspond to "food". "bulb" is a component of a "table lamp". "bulb" is not a kind of "table lamp". "watch" is a tool to display "time", instead of a kind of "time". a "truck" is a means of "transportation", instead of a type of "transportation".
