Answer:
A series of blogs created by baseball fans around the country, because people can write whatever they want in personal blog
Step-by-step explanation:
A blog created by fans can present all kinds of possible information, including false information, rumors and information with a strong bias. This is because a blog made by fans can be written by anyone who has not done an efficient research on the life of Jackie Robinson, but who wrote about him according to his own opinions, which does not promote effective and correct information.
In other words, a fan blog is the least reliable source because people can write what they want on a personal blog.
