Many museums now employ advanced laser technology to clean historic paintings, a process that removes soot and varnish without damaging the underlying paint layer. Conservators must still apply traditional methods in tandem; organic solvents, delicate scalpels, and specialized pig-hair brushes.

Which of the following options is the best replacement for the underlined portion?

  1. A
    NO CHANGE
  2. methods in tandem: organicCevap
  3. C
    methods in tandem, they are organic
  4. D
    methods in tandem, including: organic

Cevap

methods in tandem: organic
The correct choice is the option containing 'methods in tandem: organic' because the sentence before the punctuation mark is an independent clause, and the colon properly introduces a list explaining those traditional methods.

Adım Adım Çözüm

1
Identify the grammatical structure of the clause before the underlined portion.
The clause 'Conservators must still apply traditional methods in tandem' is independent because it contains a subject and a verb and expresses a complete thought.
Determining whether the preceding clause is independent is the primary step in deciding if a colon or semicolon can be used.
2
Identify the grammatical structure of the portion following the punctuation.
The phrase 'organic solvents, delicate scalpels, and specialized pig-hair brushes' is a list of nouns and not a complete sentence.
This helps eliminate punctuation marks that require independent clauses on both sides, such as semicolons.
3
Select the correct punctuation mark.
A colon is chosen because it follows an independent clause and introduces a list that directly explains the 'traditional methods' mentioned.
This matches the standard rules for colons on the ACT English section.

Anahtar Kavram
