Thanks for the help. What you gave works brilliantly for what
I described. However, the effect I described was only partial
to what I hope to achieve. I hope to be able to achieve one
of three possibilities:
1) for strong students: a blank line with the question number below -- no
first letter given
2) for weaker students: a blank line with the question number below -- first
letter given
-- this is what i described in the original post
3) for the weakest students: a line with the first letter and an additional
smaller line for each
letter of the word being tested --
I am honored to be with you today at your commencement...
becomes:
I am h __ __ __ __ __ __ __ to be with you today at your c __ __ __ __ __ __
__ __ __ __ __ ...
with a line below the entire question.
This is why I ended up using fractions in LaTeX : I can put the first
letter and the blanks for each subsequent letter in the numerator
and the question number in the denominator. The bar stays the right
length for each word.
