If a word in a sentence can be replaced by a conclusion marker without significantly changing the meaning of the sentence, then the word is used as a conclusion marker in that sentence.
Correct
ANSWER: TRUE
This substitution is good test of when a word is functioning as a conclusion marker. For example, the word “so” does not function as a conclusion marker in “He is so smart,” because this does not mean the same as “He is therefore smart.” In contrast, the word “so” does function as a conclusion marker in “He is smart, so he will probably win,” because this does mean the same as “He is smart; therefore, he will probably win.”
