Answer:
I think it's just because many people DO ask for an explanation.
Explanation:
Like, it could also be because just giving someone the answer feels like you're helping them cheat? Some people also just like explaining. if you don't want a long explanation just specify in your question beforehand.
hope this wasn't too long a story for you.
Some people plagiarize and copy from a website but others just give you a lot of information to help you understand. Instead of just saying "The answer is B," they give an explanation as to why the answer is B and sometimes why the other answers are incorrect.
I don't like the long answers either though, especially when it's a written response question that can be graded with a sample response.
