Standard English Conventions practice question

The hikers reached the summit before noon ____ they decided to rest there for an hour.

Which choice completes the text so that it conforms to the conventions of Standard English?

  1. A. noon, they
  2. B. noon, so theyCorrect
  3. C. noon so, they
  4. D. noon; so, they

Answer: B. noon, so they

Two complete sentences are being joined. A comma followed by a coordinating conjunction — here 'so' — is one of the standard ways to do that: 'noon, so they decided'.

Why the other answers are wrong

A. noon, they
A comma on its own can't hold two complete sentences together. That's a comma splice; it needs a conjunction after the comma or a stronger mark instead of it.
C. noon so, they
The comma goes BEFORE the conjunction that joins the clauses, not after it. 'noon so, they' splits the conjunction from the clause it introduces.
D. noon; so, they
A semicolon already does the joining, so adding 'so' on top of it is redundant, and the comma after 'so' has no job to do.
