DARK LINES in a Placed WORD DOCUMENT

select all and remove the paragraph rules:

- Choose Paragraph Rules from the Paragraph panel menu or Control panel menu.

- Deselect Rule On and click OK.

If it's not rules as Barb has pointed out, it's likely to be paragraph shading. This happens a lot with documents converted from Google Docs.

Any chance your documents started out that way?

Those look like paragraph rules. 

• Click in the text
• Edit > Select All
• Type > Paragraph
• Open Paragraph Rules from the Paragraph panel menu (top right)
• Disable Rule On for Rule Above and Rule Below.
  

If that doesn't do it, let us know.
