Circuits- What's the problem?

Select the missing word for both blanks by clicking on the line for a drop box word bank. The words are only used ONCE. A complete circuit is a complete path with a battery source. This circuit will not work because the wire has to connect to each end of the battery (negative end and positive end). This circuit will not work because it has an open switch (it needs to be closed) and needs wire added to the end (negative) of the battery. This circuit will not work because it has no power source (battery). Which circuit would have the brightest light?
