Passage 1
Many alkenes can be hydrated simply by treatment with a strong acid in the
presence of water. The limitation of this method is that a carbocation is
generated along the mechanistic pathway, opening the door to rearrangements,
as shown in the sulfuric acid–catalyzed hydration of 3, 3-dimethylbut-1-ene here:
One workaround for this problem is the oxymercuration-demercuration
sequence, as shown here:
,Consider the hydration of 3,6-dimethylcyclohex-1-ene under two separate
conditions, for which four different alcohol products are proposed:

Questions 6–8 are not associated with a passage.
Q6. A peregrine falcon of 9 N is a bird known for its ability to reach extremely high
speeds as it pursues prey. A bird in flight is subject to four forces: weight, drag,
, lift, and thrust. Which free body diagram accurately illustrates the direction of the
forces acting on the bird assuming the bird is moving at constant velocity?
Correct Answer Key: C
Q7. Blood is pumped from the heart at a rate of 5 L/min into the aorta of a typical
radius 1.2 cm. The velocity of blood as it enters the aorta is MOST nearly:
A. 9 cms \frac{cm}{s} scm
B. 12 cms \frac{cm}{s} scm
C. 18 cms \frac{cm}{s} scm
D. 32cms \frac{cm}{s} scm
Correct Answer Key: C
Q8. In response to a heart attack, the normal heart rhythm is restored by a
cardiac defibrillator, which transmits approximately 15 amperes of current
through the chest during a time interval of 7 milliseconds. The amount of charge
that flows during that time is:
