I am working on a puzzle to get the coordinates for a geocaching hunt. I am not familiar with photography. I've searched a lot on the internet to get my answers, but I am very confused. One or more answers I have wrong.
I am pretty certain I have all answers correct, but the ones below may be giving me the trouble.
Can you please help? Thank you so much.

1. What combination of shutter speed and aperture is equivalent to the following: 1/60 sec at f/8?
a. 1/250 sec at f/4
b.1/8 sec at f/11?
c. 1/500 sec at f/2?
* I think the answer is c.

2. Shutter speed and aperture affects what aspects of this image? (other than exposure) (order counts)
a. Depth of field and subject motion.
b. Focus distance and color balance.
c. Subject motion and depth of field.
* I had thought the answer was a.

3. Side lighting tends to emphasize....
a. Texture and volune.
b. Produces minnimal shadows.
c. Can make translucent objects seem to glow.
* I have thought answer is a.

4. A 2:1 lighting ratio...
a. Means that the lit side is two stops lighter than the shadow side.
b. Means that the lit side is one stop lighter than the shadow side.
c. Means that there are no shadows.
* I thought the answer would be b.

5. The inverse square law...
a. Says that the intensity of illumination is inversely proportional to the square of the distance from the light to the subject.
b. Results in flatter lighting.
c. Says that the intensity of illumination is directly proportional to the square of the distance from the light to the subject.
* I think answer is a.
