Colons, semicolons & hyphens

Answers and reasoning. Review before teaching.

1. Which mark separates a book’s main title from its subtitle, as in “Ocean Frontiers____ Mapping the Deep Sea”: a colon (:) or an exclamation mark (!)?
Colon (:)
A colon is the standard mark between a main title and a subtitle.
2. In “a ten-minute walk”, why is “ten-minute” hyphenated and singular: it acts as a unit modifier before the noun “walk”, or it is a plural verb?
It acts as a unit modifier before the noun “walk”
Measurement phrases before a noun (“a ten-minute walk”, “a five-kilometre run”) are hyphenated in singular form.
3. Why is the sentence “The bell rang, the students filed into the hall” a punctuation error: it is a comma splice joining two independent clauses with only a comma, or it is missing a question mark?
It is a comma splice joining two independent clauses with only a comma
Two independent clauses cannot be joined by a bare comma; use a semicolon, a full stop, or a comma plus a coordinating conjunction.
4. Which punctuation mark correctly links two closely related independent clauses without a conjunction: “The tide had turned____ the lagoon was now deep enough for the boat” (a semicolon ; or a comma ,)?
Semicolon (;)
A semicolon joins two closely related independent clauses; using only a comma creates a comma splice.
5. Which punctuation pair can set off a dramatic parenthetical aside in the middle of a sentence: “The coral reef—home to hundreds of fish species—protects the shoreline” (em dashes — or colons :)?
Em dashes (—)
Paired dashes set off an explanatory or emphatic parenthetical phrase inside a sentence.
6. Is a colon correct directly after a verb in “The three primary colours of light are: red, green and blue” (Yes or No)?
No
Do not place a colon directly between a verb or preposition and its objects; a colon should follow a complete clause.
7. Choose the correct punctuation to introduce a formal quotation after an independent clause: “Newton stated his third law clearly____ ‘To every action there is always opposed an equal reaction.’” (Colon : or Comma ,)?
Colon (:)
After a full independent clause, a colon formally introduces a quotation.
8. Choose the correct punctuation before “consequently” between two main clauses: “The reef bleached during the heatwave; consequently, fish diversity declined” or “The reef bleached during the heatwave, consequently fish diversity declined”?
The reef bleached during the heatwave; consequently, fish diversity declined
“Consequently” is a conjunctive adverb and requires a semicolon before it and a comma after it when joining main clauses.
9. Which punctuation pair encloses a quiet clarification, date range or acronym definition such as “World Health Organization (WHO)”: parentheses / round brackets ( ) or semicolons ;?
Parentheses / round brackets ( )
Parentheses enclose supplementary dates, acronyms and non-essential clarifications.
10. When list items themselves contain internal commas, which punctuation mark should separate the items: “We visited Male, Maldives____ Colombo, Sri Lanka____ and Kochi, India” (semicolons ; or commas ,)?
Semicolons (;)
Semicolons act as “super-commas” to separate complex list items that already contain commas.
11. Which short mark joins two words into a single compound adjective before a noun, as in “a well-known author”: a hyphen (-) or a semicolon (;)?
Hyphen (-)
A hyphen links words in a compound modifier before a noun (“well-known author”).
12. Which prefix almost always requires a hyphen when attached to a noun, as in “self-confidence” and “self-reliant”: self- or un-?
self-
Compounds formed with the prefix “self-” are hyphenated in standard English.
