Question 9·Hard·Boundaries
The final audit demonstrated that the updated safety protocols reduced workplace accidents by nearly 25 percent; ______ the board voted to delay full implementation until the next fiscal quarter.
Which choice completes the text so that it conforms to the conventions of Standard English?
For SAT punctuation and boundaries questions, first identify whether the parts around the blank are independent clauses (can each stand alone as a sentence). If they are, check whether the sentence uses a coordinating conjunction (like "and") or a transitional adverb (like "however"). With transitional adverbs, the standard pattern is clause; transition, clause. Avoid answers that stack multiple heavy punctuation marks (semicolon, colon, dash) together or omit the necessary comma after an introductory transitional word.
Hints
Check what comes before the blank
Notice there is already a semicolon before the blank. Ask yourself: what kind of punctuation normally follows a transition word when the semicolon has already separated the two main parts of the sentence?
Think about how transitions like "however" are punctuated
When a word like "however," "therefore," or "consequently" starts a new clause, what usually appears immediately after it to set it off from the rest of the sentence?
Avoid stacking strong punctuation marks
Try reading the sentence with each option. Which choices end up putting two strong punctuation marks (like a semicolon and then another semicolon or a dash) very close together, and which option avoids that?
Step-by-step Explanation
Identify the sentence structure
Read the sentence on both sides of the blank:
- "The final audit demonstrated that the updated safety protocols reduced workplace accidents by nearly 25 percent;"
- "the board voted to delay full implementation until the next fiscal quarter."
Each part can stand alone as a complete sentence, so they are two independent clauses joined around the blank.
Recognize the role of the missing word
The word in the blank (“however”) is a conjunctive adverb showing contrast between the two independent clauses: despite the safety improvement, the board still delayed implementation.
Standard punctuation pattern for this is:
- first independent clause
- semicolon
- conjunctive adverb (like however, therefore, consequently)
- comma
- second independent clause
In this sentence, the semicolon is already provided before the blank, so we must choose the punctuation that correctly follows the conjunctive adverb and starts the second clause.
Eliminate choices that double up heavy punctuation
Look at the options that add another heavy mark right after the semicolon:
- With a semicolon already present before the blank, adding another semicolon or an em dash immediately after the transition would create an awkward and ungrammatical string like "percent; however; the board..." or "percent; however— the board..."
- Standard English does not use a semicolon or a dash right after a transitional word that is already introduced by a semicolon.
So the choices that add another semicolon or a dash after "however" do not follow normal sentence-boundary rules.
Decide what must follow the transition word
When a transition word like "however" starts the second independent clause after a semicolon, it should be followed by a comma to separate it from the subject of the clause.
Now check each option:
- A) "however" → no comma after the transition; this leaves "however the board voted" without the standard pause.
- B) "however;" → creates "; however; the board...", which incorrectly uses back-to-back semicolons.
- C) "however—" → creates "; however— the board...", stacking a semicolon and a dash.
- D) "however," → creates "; however, the board...", which matches the correct pattern.
Therefore, the correct answer is D) however,.
