A recent study has discovered that poor children

A recent study has discovered that poor children
possess much weaker skills than wealthy children in
activities related to basic aspects of childhood play,
including running, skipping, and jumping. Given the
greater likelihood of wealthy children to have
spacious yards to play in, it is likely that this disparity
is due to a basic imbalance in the distribution of
property.

The passages in bold text play which of the following
roles in the argument?

A. The 'first is an assumption introduced by the author;
the second is an additional assumption required for
the conclusion to hold,

B. The first is a generalization that the author accepts
as true; the second offers an assumption based on
that generalization.

C. The First is evidence that the author offers in
support of a certain conclusion; the second is
that conclusion.

D. The first offers a consideration unrelated to the initial
premise; the second is a conclusion drawn from The
initial premise.

E. The first is speculation based on the conclusion
drawn in the passage; the second is a premise on
which that conclusion is based.

Apart from the Answer. PLEASE IDENTIFY THE CONCLUSION HERE. I have a bit of confusion here with respect to locating the conclusion in the above passage.
