SAT Reading & Writing: Colons and Dashes (Drill 1) is a Reading & Writing practice drill covering Colons and Dashes. It contains 5 original questions developed by Brian Stewart, a Barron's test prep author with over 20 years of tutoring experience.
SAT colon and dash questions ask you to identify whether a colon or em dash is used correctly to introduce explanations, lists, or parenthetical information. A colon must follow a complete independent clause; a dash may set off mid-sentence interruptions or emphatic additions.
Question 1. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: "The hikers faced several unexpected obstacles" is an independent clause, and the colon introduces the list that specifies those obstacles. A comma (Choice A) would fold "obstacles" into the list itself, as though it were one more item. A semicolon (Choice B) must join two independent clauses, but a list is not an independent clause. Choice D runs the clause and the list together with no punctuation.
Question 2. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: The opening dash before 'who' requires a closing dash after 'decade' to complete the parenthetical pair. You cannot open with a dash and close with a comma or other punctuation.
Question 3. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: The independent clause before the blank is followed by a list specifying which systems. A colon correctly introduces a list after a complete sentence.
Question 4. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: 'Among the items...included' is ungrammatical. 'Were' without a colon forms the correct sentence. A colon cannot directly follow a verb like 'were.'
Question 5. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: The dash opens a pair that sets off "a full return to competitive play," a supplement clarifying what the doctors had once deemed unlikely; the sentence supplies the closing dash before "and rejoined the starting lineup." Choice A completes that pair. Choice C opens the supplement with a comma, which cannot pair with the closing dash, so the marks are mismatched. Choice B places a semicolon before a phrase that is not an independent clause. Choice D joins the clause and the supplement with no punctuation at all.
