Difficulty: EasyColons

Before beginning the pottery class, the instructor listed the required materials, including: clay, a sponge, and a wire tool.

Which of the following options represents the correct punctuation for the underlined portion of the sentence?

  1. A
    NO CHANGE
  2. materials: clayAnswer
  3. C
    materials; clay
  4. D
    materials, clay

Answer

The option that replaces the underlined portion with 'materials: clay' is correct, as it properly introduces a list after an independent clause.
The correct choice replaces the error in the original sentence by placing a colon directly after the word 'materials'. This is correct because the preceding clause 'Before beginning the pottery class, the instructor listed the required materials' is independent, and the colon properly introduces the subsequent list.

Step-by-Step Solution

1
Analyze the original sentence structure to identify any errors.
The original text features a colon after 'including', which is incorrect because a colon should not separate a preposition or participle from its objects.
This shows that the original phrasing needs correction.
2
Determine if the clause preceding the list is independent in the alternative phrasings.
The clause 'Before beginning the pottery class, the instructor listed the required materials' can stand alone as a complete sentence.
A colon must always be preceded by a complete independent clause.
3
Select the correct punctuation to connect the independent clause and the list.
A colon placed after 'materials' is the correct punctuation to introduce the list of items ('clay, a sponge, and a wire tool').
This rules out semicolons (which require two independent clauses) and commas (which are insufficient to introduce a list in this context).

Key Concept

Colons must be preceded by an independent clause and can be used to introduce lists, explanations, or quotes.
