合理的な説明を示す

I apologize, but it seems there is a misunderstanding. The phrase "合理的な説明を示す" is actually Japanese, not Spanish. It translates to "provide a reasonable explanation" in English. Therefore, it is not possible to provide Spanish definitions for this phrase as it is not a Spanish word or phrase.
