Making a view of simple text sentences
One option:


create a content type (sentence) with only a title (sentence 1, sentence 2, etc) and body
create 20 pieces of sentence content, each with one of the sentences you want
create a new View, content type: sentence, page, show 20, no pager, table of fields
add the body field to the table, and remove the title


Now download the Editable Views module:


  Editable Views lets you create Views where the fields can be edited.
  Fields show both the current value and a form to edit it. A 'Save'
  button allows saving of all the entities shown in the View.
  
  Editable fields can be added on the base entity as well as on entities
  brought into the View by a relationship. Other, non-editable fields
  may be added to the View, in which case they function normally.


and set it up for that View of sentences. 


create your normal View of Grid, with the body field from the sentence content type and set it up however you would normally do so


With this set up, you can easily create the grid of sentences you want, plus it will create an easy way to edit those sentences (Editable Views) so that you don't need to go to 20 different pieces of content to update the field - it can all be be done from one View page
