3. The SIMPLIFIED STUDY copy of the STUDY copy, same but re-worded and with more pictures, for all you who can't understand the really big words in the regular one.
The Simplified version has the same pictures as the standard Study edition. It has simpler wording, but as a result, it has a higher number of words; it also includes sections for 'explaining some expressions', as well as additional 'pull quotes' (excerpts of the article in large text) on some pages. The extra content takes an additional 5 pages. As a result, the Simplified edition only contains the study articles and not the extra non-study articles (such as the 'give us money' article in the November 2013 issue) that are present in the standard Study edition.
