Given a sentence in Spanish, generate a new Spanish sentence by performing small changes on the sentence. Here, make sure that the changes are semantically related and syntactically similar to the input. And the generated sentence should have high commonsense plausibility, that is to have reasonable probability of it being true.

Let me give you an example: Es probable que encuentres un planeta en el sistema solar.
The answer to this example can be: Es desafortunado encontrar un planeta en el sistema solar.
Here is why: This is a good example of a change in the input. The created sentence is semantically similar to the input as both are talking about finding a planet in the solar system and the changes in the sentence follows the commonsense knowledge.
