Answer to Question 1

ANS: C
Newton did not consider the position of landmasses or ocean depths when giving his gravitational
model on tides. His theory would be accurate if the Earth was covered by water in a uniformed way.

Answer to Question 2

ANS: D
Neap tides are characterized as having low high tides and high low tides. These occur every two weeks
with the first and third moon phases. Information can be found in the section Tides Are Forced Waves
Formed by Gravity and Inertia.
