Astrologer: Although some scientists have claimed that there is no correlation between people’s astrological signs and their personality types, this claim is scientifically unjustified. Since science does not have precise criteria for distinguishing one personality type from another, scientific studies cannot be used to disprove a correlation between personality type and any other phenomenon.

Summarize Argument
The claim that there’s no connection between astrological signs and personality types is scientifically unjustified. Why? Well, science can’t precisely distinguish personality types, so scientific studies can’t prove or disprove anything about personality types. We don’t know enough about personality types to use them in any legitimate scientific process.

Identify Argument Part
The referenced text supports the conclusion. Why is the claim scientifically unjustified? Because scientific studies can’t be used to disprove a correlation between astrological signs and personality types.

A
It is a claim offered as support for a conclusion that is in turn offered as support for the overall conclusion drawn in the argument.
The referenced text only supports the main conclusion. It’s supported by another premise.
B
It is a conclusion for which support is offered and that in turn is offered as support for the overall conclusion drawn in the argument.
The referenced text is supported by another premise—that science doesn’t have precise criteria for distinguishing personality types—which makes it a conclusion. And it supports the main conclusion, which makes it a sub-conclusion. This is perfect.
C
It is the overall conclusion drawn in the argument.
The overall conclusion is that the claim about astrology and personality types is unjustified. The referenced text supports that claim.
D
It summarizes a position that the argument as a whole is directed toward discrediting.
The argument is trying to discredit the theory that astrology has no correlation to personality types. The referenced text isn’t summarizing that position.
E
It provides a specific instance of the general principle that the argument as a whole is directed toward establishing.
The referenced text isn’t a specific instance of anything. It’s a claim about whether or not science can draw conclusions about personality types.
