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).

Can you please explain more, if the chemical industry no longer felt compelled to oppose such action, then why such actions are still required??

The "action" the chemical industry was opposing was a ban on CFCs. The industry decided to stop opposing this ban for two reason.

First, strong political action was coming. In other words, politicians were going to outlaw CFCs. The fight for CFCs, then, was futile. The chemical industry can't fight this kind of strong political ban.

But second, the chemical industry has discovered other possible CFC substitutes. So they aren't as worried about banning CFCs anymore. It won't be worth their time to fight the politicians and try to oppose this ban.

Now, even though the chemical industry won't fight the ban anymore, the ban is still necessary. Then anyone who is using CFCs can be fairly prosecuted as participating in illegal activity. This is why if society opposes something, it should be outlawed. For instance, no one thinks stealing should be allowed. Does this mean we don't need any laws against stealing? Of course not! So, even though everyone (including chemical companies) supports a CFC ban, the ban is still necessary.
