For the second blank the “yet” contrasts with ‘hide important differences’ . Now if you are hiding something, won’t the opposite of hiding it mean that its out in open or rather someone is vocal about it , rather than hiding it.
after the blank we got ________, yet … hide important differences --> so its saying that politician are unlike (different)yet these difference is hidden by advertisements
political candidates are usually quite _____________yet their campaign advertisements often hide important differences -> Before the blank is saying that political candidates are something but their political advt. is often hiding this something or differences ( our blank ii)
So the answer is B (effective) and E (dissimilar) because yet shows the contrast so i choose the E option and from that I choose B option for blank 1. Does my interpretation and method correct?
