Introductory Challenge

Twins, Maria and Julius are in the same second-grade classroom. Both of them are outgoing and love to tell stories and jokes. Maria learned to read in Kindergarten, but Julius seems unable to make much progress with reading. What might be different about the two of them? After all, they look a lot alike, they live in the same household, and they attend the same school. But when it comes to reading, they’re not alike at all.
