Astronomer: Conditions in our solar system have probably favored the emergence of life more than conditions in most other solar systems of similar age. Any conceivable form of life depends on the presence of adequate amounts of chemical elements heavier than hydrogen and helium, and our sun has an unusually high abundance of these heavier elements for its age.

Summarize Argument
An Astronomer believes that the conditions in our solar system have likely favored the emergence of life when compared to the conditions of most other solar systems of a similar age. This is because any form of life needs adequate amounts of elements heavier than hydrogen and helium, and our sun has an unusually high supply of these heavier elements for its age.

Identify Argument Part
This is one of two premises that support the Astronomer’s main conclusion.

A
It is a statement for which no evidence is provided and that is part of the evidence offered for the argument’s only conclusion.
No evidence is provided for this claim, and it is used (alongside the rest of the sentence) to support the Astronomer’s main (and only) conclusion.
B
It is a statement for which no evidence is provided and that is offered as support for another statement that in turn is offered as support for the conclusion of the argument as a whole.
While no evidence is provided for this claim, it does not support another statement. The fact that our sun has large amounts of these heavy elements works independently does not receive any support. They both support the Astronomer’s main conclusion
C
It is a statement for which some evidence is provided and that itself is offered as support for the conclusion of the argument as a whole.
There is no evidence provided for this claim. This receives no support anywhere in the argument; it only gives support to the main conclusion.
D
It is the conclusion of the argument as a whole and is supported by another statement for which support is offered.
This is not the conclusion of the argument because it does not receive any support. The conclusion is about our solar system being more favorable for the development of life
E
It is one of two conclusions in the argument, neither of which is offered as support for the other.
This is not a conclusion because it does not receive any support. Furthermore, there is only one conclusion in this argument.
