Zorluk: OrtaCommas with Lists, Clauses, and Coordinate Adjectives

During a deep-sea exploration mission near the Mariana Trench, oceanographers launched a durable high-tech probe, and transmitted real-time thermal data back to the research vessel.

Which choice produces a grammatically correct sentence that accurately uses commas?

  1. A
    NO CHANGE
  2. durable, high-tech probe and transmitted real-time thermal dataCevap
  3. C
    durable, high-tech probe; and transmitted real-time thermal data
  4. D
    durable, high-tech probe, because transmitted real-time thermal data

Cevap

The correct option is 'durable, high-tech probe and transmitted real-time thermal data' because coordinate adjectives require comma separation and compound predicates should not be split with a comma.
The correct phrasing correctly separates the coordinate adjectives ('durable' and 'high-tech') with a comma while omitting the unnecessary comma before 'and', as 'launched' and 'transmitted' form a compound predicate sharing the same subject.

Adım Adım Çözüm

1
Evaluate the adjectives preceding the noun 'probe'.
The adjectives 'durable' and 'high-tech' are coordinate adjectives because they can be joined by 'and' ('durable and high-tech') and their order can be reversed without altering meaning.
Coordinate adjectives modifying the same noun must be separated by a comma.
2
Analyze the clause structure around the coordinating conjunction 'and'.
The subject 'oceanographers' performs two actions: 'launched...' and 'transmitted...'. This forms a compound predicate, not two independent clauses.
A comma should not separate the items in a two-part compound predicate unless a subject precedes the second verb.
