|A Second Quiz on Who||
After each sentence select the form of who that will best fit in the blank. The explanation will describe the process of arriving at the correct choice for that sentence. If you choose the correct response, it might still be a good idea to consult the explanation, to see if your explanation is the same as our explanation. For some sentences (like the first), the word should be capitalized, but capitals will not be shown in the list of possible responses.
