because it provides a syntactically 
coherent and grammatically correct sentence. 
Choices A and C are incorrect because the adverbial conjunctions 
“therefore” and “so,” respectively, are unnecessary following 
“Because.” Choice D is incorrect because it results in a grammatically 
incomplete sentence (the part of the sentence before the colon must be 
an independent clause).

information on the chart.

Choices A, C, and D are incorrect because each provides a transition 
that does not accurately represent the relationship between the two 
sentences, and as a result each compromises the logical coherence of 
these sentences.
