Daily Olympiad: English - Punctuation [20260610]

Solution

Correct: B

In a sentence with an introductory dependent clause followed by an independent clause, a comma is necessary to separate the two. 'After the storm passed' is the dependent clause, and 'we decided to go outside' is the independent clause. The comma before 'we' properly divides them.

Solution

Correct: B

A semicolon joins two independent clauses in a sentence without a conjunction. 'My brother loves pizza' and 'he also enjoys sushi' are both independent clauses, so a semicolon is the correct punctuation to combine them without an additional conjunction.

Solution

Correct: A

Nonrestrictive clauses provide extra information and are set off with commas. 'Which I borrowed from the library' is a nonrestrictive clause explaining the book, so commas correctly isolate it. 'That' is incorrect for nonrestrictive clauses because it removes the commas.

Solution

Correct: B

When joining two independent clauses with a coordinating conjunction like 'but,' a comma is placed before the conjunction. Both 'We went to the park' and 'it rained all day' are independent clauses.

Solution

Correct: A

A compound predicate contains two or more verbs connected by a conjunction. When the conjunction joins two verbs within the same clause, no comma is needed. 'Opened the door and walked in quickly' is the compound predicate here, so no comma is required.

Solution

Correct: A

A colon is used to introduce an explanation or list that directly relates to the preceding independent clause. In this case, the colon correctly introduces the rule described in the sentence.

Solution

Correct: A

An appositive phrase that is nonessential to the sentence (i.e., can be removed without losing meaning) is set off by commas. 'Who lives in France' is nonessential information about the brother and should be enclosed in commas.

Solution

Correct: B

A participial phrase should be followed by a comma to separate it from the rest of the sentence. 'Running quickly' is a participial phrase modifying 'he,' so a comma is needed before the independent clause begins.

Solution

Correct: D

A semicolon can be used before 'however' when it acts as a transitional word to join two independent clauses. The comma after 'however' is required for proper punctuation in this structure.

Solution

Correct: B

When listing three or more items in a sentence, commas separate each item, including a comma before the conjunction 'and' (Oxford comma). This rule ensures clarity and prevents ambiguity in the sentence structure.
