This type of sub-menu item demand special constructor attention towards quality, so come to include basic considerations for its development:

 Prefer phrases or prayers built, rather than textual or taken from books or other documents.

 Avoid the use of articles before the empty space, because it lends itself so that the learner guessing the answer or insert other larger than the required.

 Ensure that the required response adjust space provided.

 Fit empty space to be a column in the right margin with a uniform length.

This suggestion makes the grade.

 In the case of empty space to claim a single response.

 Avoid forms before the empty space, verbal is, are, were, were and any other of the conjugation of the infinitives be and, as these give the item a character ambiguity.

 Draft text which uses shaped affirmative.

 Assign to each item complete worth one point, since it is a single task, a unique concept and a difficult one.
