question: bait:fishing rod
choices.label: A B C D
choices.text: pen:book computer:wireless router spatula:frying pan writing poems:pen
explanation: the "bait" and the "fishing rod" can only work together when used together. "pen" and "book" can be used without matching. "computer" and "wireless router" can also be used without matching, and a "computer" does not need to have a "wireless router" to access the internet. the "spatula" and the "frying pan" can be used together to function. "writing poetry" and "pen" can be used without matching, and "writing poetry" is not a tool.
