In a 2016 study, Eastern Washington University psychologist Amani El-Alayli found that, among the study participants who
experienced frisson (a physiological response akin to goosebumps or getting the chills) while listening to music, there was
one personality trait that they scored particularly ______ openness to experience.
high. On
high on;
high on
high on:
Choice D is the best answer. The convention being tested is punctuation use between a main clause and a supplementary
phrase. In this choice, a colon is correctly used to mark the boundary between the main clause ("there...on") and the
supplementary phrase ("openness to experience") and to introduce the information that identiﬁes which personality trait
participants scored especially high on.
Choice A is incorrect because it results in a rhetorically unacceptable sentence fragment beginning with "on" and separates a
necessary preposition from the clause beginning with "there." Choice B is incorrect because a semicolon can’t be used in this
way to join the main clause ("there...on") and the supplementary phrase ("openness to experience"). A semicolon is
conventionally used to join two main clauses, whereas a colon is conventionally used to introduce an element that explains
or ampliﬁes the information in the preceding clause, making the colon the better choice in this context. Choice C is incorrect
because it fails to mark the boundary between the main clause ("there...on") and the supplementary phrase ("openness to
experience").
