    A very famous amplifier company once used to advertise their amplifiers as

    " A straight piece of wire with gain "

    So many 'ideal' components react the same at all frequencies, from a dead short circuit to a length of (ideal) connecting wire to an ideal amplifier to an ideal adder to an 'and gate' ..............

    You have now been given two components, vis a dead short and an open circuit. A component that provides both is a switch (relay) and also reacts equally to all frequencies.

    Use your imagination.
