Which option correctly punctuates the underlined portion of the sentence?

  1. NO CHANGECevap
  2. B
    parameters, constant temperature,
  3. C
    parameters including: constant temperature,
  4. D
    parameters; constant temperature,

Cevap

The correct answer is the option that keeps the original punctuation (NO CHANGE), which uses a colon to introduce the list of environmental parameters after a complete independent clause.
The correct answer maintains the colon. In English grammar, a colon is used to introduce a list or explanation only when it is preceded by a complete independent clause. Since the clause before the colon can stand alone as a sentence, and the words following it comprise a explanatory list of the parameters, this punctuation is correct.

Adım Adım Çözüm

1
Analyze the clause preceding the underlined portion to determine if it is independent.
The clause 'To protect the fragile clay tablets from humidity, the archive maintains three strict environmental parameters' contains a subject and a verb and can stand alone as a complete sentence.
A colon can only be used if it is preceded by a grammatically complete independent clause.
2
Evaluate the grammatical function of the text following the underlined portion.
The text 'constant temperature, low light, and low moisture levels' is a list of three noun phrases that explains and defines the 'three strict environmental parameters.'
A colon is the appropriate punctuation mark to introduce a list, explanation, or amplification that directly explains the preceding independent clause.
3
Assess the options to find the one that maintains this correct punctuation structure without introducing errors.
The option containing the colon and comma list structure is correct. Replacing the colon with a comma, a semicolon, or placing it after the word 'including' violates standard ACT punctuation rules.
Commas cannot introduce lists in this manner, semicolons require independent clauses on both sides, and colons cannot follow prepositions or introductory words like 'including.'

Anahtar Kavram

Colons must be preceded by a complete independent clause and are used to introduce lists, explanations, or summaries.
