Hi @capoleway@gmail.com

Happy to help!

The author concludes that it is not surprising that environmentalists fail to consider the negative effects of space flight.

Why? Because space-based satellites allow for earlier observation of environmental issues meaning that these issues can be addressed before they become crises.

Answer choice (B) is incorrect because the author suggests the opposite in their final sentence, noting that the damage spacecraft may cause to the ozone layer "could be serious enough to warrant discontinuing space flight."

Answer choice (A) is correct because it directly supports the author's conclusion.

People (environmentalists) tend to ignore possible objectionable consequences (impacts of spacecraft) of actions (space flight) that support their activities (conservation and addressing environmental issues).

Hope this helps! Please let us know if you have any further questions.
