Question

What is the best definition for the underlined word based on the following sentence? "As a young boy, Mark Twain has his heart (invariably) set on becoming a riverboat captain."

A. Thoughtlessly
B. Carefully
C. Without change
D. Constantly going back and forth

Answer 1

C. without change

Invariably means in every case or occasion, always.

Answer 2

The correct answer is C. Without change

Variably comes from the verb to vary which means to change. Invariably is the opposite of that meaning that there is no change at all. Thoughtlessly means that he didn't think about it while he can invariably think something without being careful about it. Going back and forth is another concept also not related to the sentence.
