My question to Mr. Hunt or other Experts:

emotional reactions in an individual that

Why is "that" not referring to the noun "individual", but emotional reactions. Just because "individual" is a part of a prepositional phrase. I normally have seen that refers to the noun that it touches.

Hello Everyone!

Let's tackle this question, one issue at a time, and narrow it down to the correct choice quickly! To get started, here is the original question with the major differences between the options highlighted in orange:

The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual that, in turn, create unconscious physiological responses.

(A) that, in turn, create unconscious physiological responses
(B) that creates unconscious physiological responses in turn
(C) creating, in turn, unconscious physiological responses
(D) to create, in turn, physiological responses that are unconscious
(E) who creates unconscious physiological responses in turn

After taking a quick glance over the options, there are a lot of differences we can focus on. Here are just a couple to start:

1. creates / create / creating (subject-verb agreement)
2. placement of the phrase "in turn" (idioms)


Let's start off with #1 on our list: subject-verb agreement. To find out whether we need a singular or plural verb here, we need to ask ourselves, "WHAT is creating unconscious physiological responses?" Next, we need to look to the original sentence for clues:

The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual that, in turn, create unconscious physiological responses.

Now that we know the verb is tied to the plural subject "reactions," we need to make sure the options use plural verbs to match:

(A) that, in turn, create unconscious physiological responses
(B) that creates unconscious physiological responses in turn
(C) creating, in turn, unconscious physiological responses (No verb issues, but let's save this one for later anyway)
(D) to create, in turn, physiological responses that are unconscious
(E) who creates unconscious physiological responses in turn

We can eliminate options B & E because they don't use proper subject-verb agreement. Now that we have it narrowed down to only 3 options, let's move on to another issue on our list.

Let's focus now on the placement of the phrase "in turn." In English, we use this phrase to indicate cause-effect among a series of actions:

X causes Y, and Y, in turn, causes Z

If we look at the original sentence, we can get some clues as to what X, Y, and Z are in our idiom:

The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual that, in turn, create unconscious physiological responses.

X = lying
Y = emotional reactions
Z = unconscious physiological responses

Now that we know what to plug into our equation, let's see which options handle this idiom correctly. To make it easier to spot, we've included the rest of the phrase for you:

(A) lying produces emotional reactions in an individual that, in turn, create unconscious physiological responses

X (lying) causes Y (emotional reactions), and Y (emotional reactions), in turn, causes Z (physiological responses) = CORRECT!

(C) lying produces emotional reactions in an individual creating, in turn, unconscious physiological responses

X (lying) causes Y (emotional reactions), and Y (emotional reactions) causing, in turn, Z (physiological responses) = WRONG!

(D) lying produces emotional reactions in an individual to create, in turn, physiological responses that are unconscious

X (lying) causes Y (emotional reactions) and Y (emotional reactions) cause, in turn, Z (physiological responses) = WRONG!


There you have it - option A is the correct choice! It uses proper subject-verb agreement, and the idiom (X causes Y, and Y, in turn, causes Z) is written correctly!

The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual that, in turn, create unconscious physiological responses.


(A) that, in turn, create unconscious physiological responses

(B) that creates unconscious physiological responses in turn
The positioning of the causal relationship in turn is in the end and distorts the meaning of the sentence.

(C) creating, in turn, unconscious physiological responses
We are stating a fact and thus a continuous tense creating is not required

(D) to create, in turn, physiological responses that are unconscious

this is a passive voice sentence and an active voice is preferred.
(E) who creates unconscious physiological responses in turn
Individual is not creating responses. They are created automatically.
