I would not have given the students any special
preparation for "doth," and I would expect most students at this stage
to miss it. (I would praise those who get it.)
In grading the quiz, ignore whatever students
do with "raising: and "feeding" in the last two lines. In reviewing the
quiz, praise those students who did not underline these words twice, and
point out to the others that, as used here, these verbs do not form sentences.
("Their head never raising" is not an acceptable sentence, and neither
is "forty feeding like one.")
