write one best example of improbable conditional sentence.

If I had a million dollars, I would buy a private island and live there with a herd of unicorns that I magically befriended.

One classic example of an improbable conditional sentence is as follows:

"If pigs could fly, then it would be easier to travel long distances."

In this sentence, the condition being presented is that pigs have the ability to fly. However, this is an impossible scenario since pigs are incapable of flying. The consequence or result of this improbable condition is that it would make long-distance travel easier. This sentence is often used to highlight absurd or unlikely situations.
