Incorrect. First, we have to assume that an unfair relationship is unjust for this answer to be in scope. Even then, the stimulus states that relationships weren't necessarily pleasant or fair, not that they were unpleasant or unfair as a matter of course.

Correct. Argument or Facts:
Facts

Question Type:
Argument Completion (Must Be True)

Stimulus Summary:
Preagricultural societies - Social roles were few and clearly defined, so interpersonal relationships were stable and predictable
Modern society - Social roles are numerous and constantly changing, so __________

Answer Anticipation:
This Argument Completion question leads into its blank with a "Therefore", letting us know that it's presenting us with the premises and asking us for the conclusion. As such, this is a Must Be True variant, so we should see what we can prove based on the premises given.

Here, the stimulus is very much about the comparison between preagricultural societies and modern society. For both, we learn about the social roles. They were few and clearly defined in the past; they're numerous and constantly changing ("differentiating at an astonishing speed") in the present. The characteristics of social roles in the past caused ("Accordingly") interpersonal relationships to be stable and predictable, but the stimulus doesn't discuss interpersonal relationships in the present, so that must be where the conclusion is headed.

As such, since the social roles that led to stable and predictable relationships have completely reversed their characteristics, we can conclude that the relationships have similarly reversed their characteristics and are no longer stable and predictable. Let's find that as an answer.

Answer Explanation:
The few social roles that were easily predicted led to preagricultural relationships being stable and predictable. As such, since modern society lacks those characteristics in its social roles, we can conclude that relationships are less stable and predictable, as this answer states. This argument completes the missing part of the comparison, so it's the correct answer.

Key Takeaway:
Argument Completion questions frequently deal with comparisons. See if you can identify a missing "piece" in one element of the comparison, and that'll likely be the correct answer.

Incorrect. The stimulus doesn't discuss other differences or use superlative language to describe this one, so this answer is too strong.

Incorrect. Predicting the actions of others is out of scope of the argument, especially requiring technology to do so.

Incorrect. This answer brings up a weird world from a sci-fi novel or something where everyone is assigned an appropriate/stable social role—it's completely out of scope of what this stimulus is talking about.
