Low quality posts are often reported by the users because they are mostly considered as spam by those users and when moderators get the reports and go through those posts and find them as spam as well then they delete those posts. Your post were one liner posts and most of the one liner posts are done by the new users because they want to increase their activity with those posts. But, like Philipma1957 has said that your posts weren't too bad, however, I still recommend you to expand your posts a little if you have more information about a topic.

It's not necessary to be extra knowledgeable to expand your posts from one liner to somewhat well structured. You just have to focus more on reading and it's really necessary to read as many posts in a thread as possible before making your posts. Look we all are here for the purpose of learning and then sharing our knowledge in the form of threads and replies and if someone knows more then that user can create well-structured posts.
