Rearrange the given groups of words to make a meaningful sentence:

A. then the world will avert all future wars
B. and agree to obey all the laws
C. if all the nations work together
D. for the common good of mankind

Choose the correct answer from the options given below:

D, B, A, C

The correct answer is D, B, A, C.

The sentence should read:

If all the nations work together for the common good of mankind, then the world will avert all future wars and agree to obey all the laws.

The other options do not form a grammatically correct sentence.

Here is a breakdown of the sentence structure:

• If is a subordinating conjunction that introduces a dependent clause.
• All the nations work together is the main clause.
• For the common good of mankind is an adverbial phrase that modifies the main clause.
• Then is a coordinating conjunction that joins the dependent clause to the main clause.
• The world will avert all future wars is the second independent clause.
• And agree to obey all the laws is an adverbial phrase that modifies the second independent clause.
