A 25-Word Transit Alert: Choosing Among Three Drafts
A transit agency has 25 words for a push notification about Sunday service. The writer produces three drafts:
A. "Because Route 7 will be rerouted on Sunday, riders should check the app before leaving home." B. "Route 7 will be rerouted on Sunday, riders should check the app before leaving home." C. "Route 7 will be rerouted on Sunday. Riders should check the app, before leaving home."
A supervisor also flags a line from the website: "Only after the bridge reopens the Route 7 will return to its normal schedule." The notification must stay under 25 words, keep the route name and the word "Sunday," and read correctly to a rider skimming on a phone.
1. Which draft should be sent, and what is wrong with the other two?
Read the worked answer
Send A. It is a single sentence of 18 words, in the 25-word limit, and the subordinator Because makes the reroute the reason for the advice - the logical link a skimming rider needs.
B is a comma splice. Route 7 will be rerouted on Sunday and riders should check the app are both independent clauses; a comma alone cannot join them.
C is punctuated but mis-signposted. Two separate sentences are grammatical, yet the comma after app wrongly separates the verb from its own modifier before leaving home. It also drops the causal link, so the reader gets two facts with no stated connection. Separate sentences are not an error in themselves - the misplaced comma is.
Note that C could be repaired simply by deleting the comma; the choice between A and repaired C is about clarity, not correctness. A wins on clarity.
2. Rewrite draft B two different ways, staying under 25 words at each attempt, and name the structure you used.

Version 1 - semicolon (coordination): "Route 7 will be rerouted on Sunday; riders should check the app before leaving home." (16 words) A semicolon can join two independent clauses when the writer wants them tightly linked. Both halves remain full clauses.
Version 2 - subordination: "Since Route 7 will be rerouted on Sunday, riders should check the app before leaving home." (18 words) Here one clause becomes dependent, so the comma is now doing a legitimate job: separating an introductory dependent clause from the main clause.
A third option is to make one clause a modifier: "Riders on Route 7 should check the app before leaving home on Sunday, when the bus is rerouted." (19 words)
All three fix B; the semicolon keeps the two ideas equal, while subordination ranks them and makes the advice the point.
3. Repair the website line: "Only after the bridge reopens the Route 7 will return to its normal schedule." Explain the word-order problem.

Corrected: "Only after the bridge reopens will Route 7 return to its normal schedule."
The problem is inversion. When a sentence opens with a negative or restrictive expression - only after, never, rarely, not until - the auxiliary moves in front of the subject: will Route 7 return, not Route 7 will return. The original leaves the subject-verb order of a plain statement after a fronted restriction, which is why it reads as if a word is missing.
Removing Route 7 from the phrase the Route 7 also helps: the route name functions as a proper name here, so the article is unnecessary.
A simpler alternative that avoids inversion altogether: "Route 7 will return to its normal schedule only after the bridge reopens." Same meaning, ordinary word order, safer if the writer is unsure.
