With the 1985 discovery of an ozone hole over Antarctica, an international ban on the production of chlorofluorocarbons - implicated in causing the ozone hole - began to appear (i) __________ ,especially since chemical companies' opposition to such ban had weakened.
Blank (i)
(A) imprudent
(B) fortuitous
(C) premature
(D) imminent
(E) unlikely
when ozone hole was discovered, chlorofluorocarbons were banned.
began to appear (i) __________ something was to happen...
,especially since chemical companies' opposition to such ban had weakened.chemical companies opposed this decision though it was weakening.
so here is the contrast.
once the opposition is weakening surely the ban will be strong or positive something
imminent = about to happen
fits perfectly here.
