OE“Badly miscalculated” indicates that there are two opposing parts of the sentence: the candidate’s
“prepared speeches” are good, but some other form of communication is bad. You need two words that mean improvised or off-the-cuff:
“extemporaneous” and
“impromptu” are a perfect fit.
“Capricious” (whimsical or variable) is tempting but doesn’t pair as well as the two correct answers.
“Lubricious” and
“disingenuous” form a pair relating to dishonesty that is unrelated to the clues and might be a trap (if you insert your own, negative ideas about politicians). Finally,
“premedititated” would apply to the
“prepared speeches,” not the off-the-cuff communication.
