Explanation

According to the first sentence, chemical companies opposed a ban on CFCs and then changed their stance in 1985 with the discovery of an ozone hole.
In the first blank, only “imminent” is compatible with the discovery of an ozone hole linked to CFCs: such a discovery would suggest that “strong political action” is required, not that it is “imprudent” or “premature.”

What follows the colon in the second sentence explains why the chemical industry “no longer felt compelled to oppose” a ban on CFCs. In order for the industry to drop its opposition, the outcome of the studies into CFC substitutes must have been positive. Among the choices for the third blank, only “encouraging” has a sufficiently positive connotation.

Finally, the word “although” after the colon indicates that the second blank should contrast with the third blank in some way. Since the completed third blank now indicates that studies of CFC substitutes have been successful, “curtailed” makes the most sense in the second blank. “Corroborated” and “publicized” do not contrast appropriately with the success of the studies.

Thus, the correct answer is imminent (Choice A); curtailed (Choice F); and encouraging (Choice G).
