When a bird flies, powerful forces converge on its shoulder joints. The bird’s wings must be kept stable during flight, which cannot happen unless something balances these forces. The only structure in birds capable of balancing them is a ligament that connects the wing to the shoulder joint. So that ligament must be _______.

Summary
Any time a bird flies, powerful forces converge on its shoulder joints. If they are flying, the bird’s wings must be kept stable during flight. If their wings are stable, something needs to balance these powerful forces. The only structure in birds that can balance these forces is a ligament that connects the wings to the shoulder joint. So that ligament must be (the correct answer is the conclusion).

Strongly Supported Conclusions
The ligament is how birds stabilize their wings while flying.
Bird Flying -> wings stable -> balance powerful forces

A
the only structure that is indispensable to bird flight
The stimulus gives no indication that this ligament is the *only* structure necessary for bird flight. This is too strong to support and does not follow logically from the argument.
B
the reason that a bird’s wings must be kept stable during flight
The stimulus does not explain exactly *why* the bird’s wings must be kept stable. The stimulus is primarily concerned with the importance of stability, but not the reasons for it.
C
the sole connection between the wing and the shoulder joint
The stimulus says that the ligament is the only structure *capable of balancing* the wings, not that it is the sole connection. This is too strong to support.
D
the source of the powerful forces that converge on the shoulder joint
The stimulus does not explain where these powerful forces come from. The stimulus only says that these ligaments *balance* the powerful sources.
E
the means by which a bird stabilizes its wings during flight
The stimulus says that *the only structure* capable of balancing the wings is this ligament. Thus, the ligament must keep its wings stable because nothing else can.
