Determine the appropriate use of a dash in scholarly writing: 'The policy—if implemented—could affect several sectors.'

Determine the appropriate use of a dash in scholarly writing: 'The policy—if implemented—could affect several sectors.'

• A. To set off an aside or emphasize a break in thought.
• B. To indicate a missing word.
• C. To join independent clauses.
• D. To mark a range of numbers.

Answer: (A)

Using a dash to set off an aside or emphasize a break in thought is the main idea here. The phrase between the dashes—“if implemented”—acts as a brief, nonessential aside that qualifies the policy. The em dashes signal a sharp, parenthetical interruption, letting the reader pause and consider this condition without breaking the sentence flow. This keeps the focus on the main claim that the policy could affect several sectors, while still noting that an additional condition could change that outcome. The other options don’t fit this usage. A missing word would usually be shown in other conventions like ellipses or brackets, not by this kind of dash. Joining independent clauses with a dash would typically connect two complete statements, whereas the inserted phrase here is not an independent clause. Marking a range of numbers is done with a hyphen or en dash, not with two em dashes enclosing a phrase.
