When the plot of a story deals with time travel, some readers have a difficult time stepping back from thoughts about how events could actually work. In Alix E. Harrow’s exceptional novel The Everlasting, for example, the near perpetual time _____ some of which understandably disorient the characters themselves, can leave a reader’s head spinning.
The correct answer is (A).
current priority level - we all want this one
What is before the potential semicolon in option (D) is not a complete sentence. So, our first action could have been here to evaluate option (D) and then strike it out.
Given what we just said, we can also strike out option (C), as what comes before a colon should be a complete sentence.
From here, it would be great to know precisely why you are selecting the comma that we see within option (A), as a classic appositive is in place. The phrase “some of which understandably disorient the characters themselves”…
Given what’s above, we would want to bracket the phrase with another comma, as there is already a comma after the word “themselves”.
Depending on what Path you are currently on, it can work to pick an option with a comma or not pick an option with a comma by instinct. But, it would likely be better to have CONCRETE reasons for the commas we use(especially since the test writers really seem intent on letting this be a thing).
