Which choice best maintains standard written English in the underlined portion?

  1. NO CHANGECevap
  2. B
    resilient adaptive microfossils; cataloged mineral compositions, and recorded
  3. C
    resilient, adaptive microfossils cataloged mineral compositions and recorded
  4. D
    resilient, adaptive microfossils, they cataloged mineral compositions, and recorded

Cevap

The original phrasing 'resilient, adaptive microfossils, cataloged mineral compositions, and recorded' is correct.
The original text correctly places a comma between the coordinate adjectives 'resilient' and 'adaptive' and correctly uses serial commas to separate the three parallel verb phrases that complete the compound predicate.

Adım Adım Çözüm

1
Evaluate coordinate adjectives
The adjectives 'resilient' and 'adaptive' both modify 'microfossils' independently (e.g., 'resilient and adaptive microfossils'), so a comma is required between them.
Coordinate adjectives modifying the same noun require a comma separator.
2
Identify items in a series
The sentence lists three parallel past-tense verb phrases: (1) identified resilient, adaptive microfossils, (2) cataloged mineral compositions, and (3) recorded thermal fluctuations.
A list of three or more items requires commas separating each item, including before the coordinating conjunction.
3
Select the option that applies both comma rules accurately
The unchanged phrasing contains the necessary comma between coordinate adjectives and all required serial commas.
It maintains proper grammatical structure without creating fragments or comma splices.
