Rockabilly music is ______ of two other genres: it combines elements of rock & roll and country music.

(A) a chasm
(B) an amalgamation
(C) an impression
(D) a tonic
(E) a fission

The correct answer is B
Explanation: To find the missing word, try to predict its meaning by using clues in the sentence. Here, the main clue is the colon, which separates explanatory information from the rest of the sentence. In this sentence, the fact that rockabilly "combines elements" of other music forms describes what rockabilly music is in relation to "to other genres": a mixture. The correct answer, thus, is B, as an "amalgamation" is "the result of combining or uniting separate things."

None of the other choices work, either:

chasm: a profound division or difference
impression: an imitation of something or someone done for comic effect
tonic: a medicinal substance taken to give energy or a feeling of well-being
fission: the action or result of dividing something into two parts
