An observer on Earth measures the angle of sight between Venus and the setting Sun.
Which statement best describes and explains the apparent motion of Venus over the next few hours?
(1) Venus will set 1 hour after the Sun because Earth rotates at 45° per hour.
(2) Venus will set 2 hours after the Sun because Venus orbits Earth faster than the Sun orbits Earth.
(3) Venus will set 3 hours after the Sun because Earth rotates at 15° per hour.
(4) Venus will set 4 hours after the Sun because Venus orbits Earth slower than the Sun orbits Earth.

(2) 30° N
(3) 60° N
(4) 90° N

On the diagram in the image provided, place an X on each of the two positions of the Moon in its orbit where neap tides (the smallest difference in the water levels between high tide and low tide) occur. 
Allow 1 credit if the centers of only two Xs are placed on the diagram – one to indicate the 1st quarter phase and one to indicate the 3rd quarter phase, as shown below.
State the time at San Francisco, California, when it is 12 noon at New Orleans, Louisiana. Indicate a.m. or p.m. in your answer. 
Allow 1 credit. Acceptable responses include, but are not limited to:
• — 10:00 a.m.
• — 10 am
• — 1000 (military time)
• — 10 in the morning
The Sun travels 45° in its apparent path between the noon position and point A. Identify the time when the Sun is at point A. Include a.m. or p.m. with your answer. 
Allow 1 credit for 3 p.m. or 3:00 p.m.
• Note: Allow credit if the “p.m.” lacks periods.
Predict the length of the object’s shadow at 2:30 p.m. 
Allow 1 credit for any value from 130 cm to 160 cm.
State the time at location A when it is noon at location B. Indicate a.m. or p.m. in your answer. 
Allow 1 credit for a response that indicates a time value of 9 a.m. Acceptable responses include, but are not limited to:
• — 9:00 a.m.
• — 9 o’clock in the morning
