Question: Towards the end of a game, a team's pitcher begins to lose his
focus and shortens his stride, uncoupling the kinetic chain at his hips. How will
this impact his pitch?
(A) It will make his shoulder more injury-prone as a result of the increased
energy being dissipated during the follow-through from the inefficient kinetic
chain.
(B) It will decrease the velocity of the pitch due to a decrease in energy
transfer through the torso
(C) It will decrease the velocity of the pitch as a result of the increased energy
being dissipated during the follow-through from the inefficient kinetic chain
(D) It will decrease the velocity of the pitch due to a decrease in the ability to
generate force in the legs

Answer: O: (A) - reason being that I did not think that the power generation
would change, but did think that the transfer would change and that the
passage said that the shoulder would need to rotate more to deplete the
energy taken from the legs. The uncoupling in this case comes before the
shoulders, so they should not have been considered.
C: (B) - the fact that the kinetic chain uncouples at the hips (READ
QUESTIONS AND TAKE INFORMATION FROM THEM) means that there is
going to be a larger loss of energy at that point, leading to lower available
energy at the upper torso and shoulders, thereby reducing the pitch velocity.
Question:
If researchers failed to take into account the effect of air resistance on the
pitch, how would it impact their measurements of the efficiency of energy
transfer from the arm to the baseball?
(A) It would be lower than the actual efficiency, as there was higher initial
velocity at release
(B) It would be higher than the actual efficiency, as there was a higher initial
velocity at release.
(C) It would be lower than the actual efficiency, as there was a lower initial
velocity at release
(D) It would be higher than the actual efficiency, as there would be a lower
initial velocity at release

Answer: O: (C) - The pitch would be slowed down by air resistance, which is
why I picked this answer (this is a two-part answer and I got the first part
right). However, the reasoning behind why the first part was incorrect, and I
was thinking that the initial velocity was impacted by air resistance, which is
wrong (air resistance does not have a strong effect right when the ball exits
the hands)
C: (A) - This is correct because the initial velocity is going to be much higher
than the velocity that the ball has once it reaches the plate (it slows down
because of air resistance, but it starts out much faster)
Question:
How does the magnitude of an enthalpy barrier correspond with reactivity?
Answer: The lower the enthalpic barrier, the more active the reaction
(because it is easier to surmount the barrier)
Question:
When Bs1A is assembled as an octamer, what is most likely to be true
regarding L76, L77, and L79?
(A) They are oriented toward the solvent-exposed exterior of the protein
assembly
(B) The assembly would incur an entropic penalty if they occupied a solvent-
exposed site
(C) Unlike in a monomer, they are not situated within the hydrophobic cap
, Page | 4
(D) Their physiological properties are not substantially dependent on their
hydrophobicity
Answer: O: (C) - The passage does not indicate that the residues are removed
from the hydrophobic cap, they are just shielded (which does not induce
translocation of any kind)
C: (B) - This makes sense because, in a situation with hydrophobic residues
being exposed to solvent, there will be a formation of some sort of salvation
order and there will consequently be an unwanted decrease in entropy
(entropy tends to increase). Thus. there would be an entropic penalty should
they have remained exposed.
Question:
Presbyopia is diagnosed when the lens of the eye focuses incoming light rays
to a position between the retina and the choroid. Which type of lens should be
placed in front of the eye to focus light on the retina and correct this
condition?
(A) Flat
(B) Spherical
(C) Diverging
(D) Converging
