For each of the alternative forms, give the standard (fuller) form which you have already learned (note that eo, for which you learned perfect ii, has a fuller form ivi, or other requested form.
Example:
diffugere
Answer: diffugerunt (it's true that, without macrons, diffugere,
short -e- and -u-, could also be the present infinitive,
while diffugere with long -e- and -u- could be present perfect, for diffugerunt,
but be guided by the forms given in this chapter).
Go to the previous exercise.
