    NO CHANGE
  2. unpredictable, destructive insect pests, they recommendedCevap
  3. C
    unpredictable destructive insect pests; they recommended
  4. D
    unpredictable, destructive insect pests. They recommended

Cevap

The correct option is the one that reads 'unpredictable, destructive insect pests, they recommended'. This choice correctly punctuates the coordinate adjectives and sets off the introductory clause.
The correct choice properly identifies that 'unpredictable' and 'destructive' are coordinate adjectives modifying 'pests' and therefore require a comma, whereas 'insect' is a cumulative adjective (functioning as a noun adjunct) that should not be separated by a comma. Additionally, because the sentence starts with the subordinating conjunction 'Because', the introductory clause is dependent and must be separated from the main clause by a comma after 'pests'.

Adım Adım Çözüm

1
Determine if the adjectives modifying 'pests' are coordinate or cumulative.
'Unpredictable' and 'destructive' are coordinate because they can be reversed and joined by 'and'. However, 'insect' is cumulative because it directly modifies 'pests' as a single unit ('insect pests').
Coordinate adjectives require a comma between them, while cumulative adjectives must not be separated by a comma.
2
Identify the clause boundary and determine the appropriate punctuation.
The sentence begins with the subordinating conjunction 'Because', making 'Because the regional agricultural board wanted to protect local crops from the unpredictable, destructive insect pests' a dependent clause.
An introductory dependent clause must be followed by a comma when it precedes an independent clause.
3
Evaluate the choices to find the one that applies both rules correctly.
The choice containing 'unpredictable, destructive insect pests, they recommended' is the only option that correctly includes the coordinate comma, excludes the cumulative comma, and uses a comma to separate the clauses.
This correctly resolves both the adjective punctuation and the clause boundary punctuation.
