7. choose the word that best fills in the blank. he went into a long about the outcome of the last election after it was mentioned on the news. a. quibble b. fastidious c. assert d. rant

The type of word needed is an action noun (not an act) one can perform on their own, as it is given the quantity of "a long" and you do not use adjectives to describe verbs. it would be D. Rant, as quibble. though it is a noun, you do not quibble alone, nor do you go on a quibble. You go on a rant. The other two are B. an adjective and C. a verb. D is the only word that truely fits the context.
