Sorry, but the paragraphs you have asked about are NOT indented. I know this is confusing beccause the entire paragraph does appear to be indented in print. Howeer, that arrangement is ignored in braille. The FIRST LINE only of a paragraph determines whether it is indented in braille.
When all the lines of a paragraph start at the same margin, as these do in your print, the paragraph is BLOCKED and all of it is blocked in cell 1 with runovers also in cell. There should be blank line before and after such a paragraph. When the FIRST LINE ONLY of a paragraph is indented relative to the rest of the paragraph, that first line is also indented to cell 3 in braille with runovers in cell 1.
This is a basic formatting rule and is not unique to foreign language, even though this text happens to be foreign language braille. Since you have paragraphs in the midst of this exercise material, have a blank line before and after each of these paragraphs and block each such paragraph in cell 1 as described above. The material before and after the paragraph should be in the exercise format you have established.
