Standard English Conventions practice question

There was one flaw in the otherwise careful plan ____ nobody had checked the tide tables.

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

  1. A. plan: nobodyCorrect
  2. B. plan, nobody
  3. C. plan nobody
  4. D. plan; and nobody

Answer: A. plan: nobody

The first clause announces a flaw; the second says what it was. A colon after a complete clause introduces exactly that kind of explanation.

Why the other answers are wrong

B. plan, nobody
Both halves are complete sentences, so a comma alone is a splice.
C. plan nobody
Nothing at the boundary leaves two sentences run together.
D. plan; and nobody
A semicolon would work alone, but adding 'and' after it is redundant.
