This was question 2
List all of the following factors that affect the period of this simple pendulum.
A. The mass of the object
B. The length of the string
C. Angles less than 10 degrees
D. Acceleration due to gravity
The original question can be found at this link and contains more information.

I also provided the online simulation from Phet.Colorado.edu to do investigations.
The correct answers are
B. The length of the string and D. Acceleration due to gravity
(B and D)
I was hoping that the simulation would give some help in figuring out the answers. After looking at it very closely, you had to select the Lab tab and enable the embedded Period Timer so you are not guestimating the period. See the screenshot.
If you did this you see that when the angles are less than 10 degrees the period is generally the same within the first two decimal places.
Unfortunately no one got the correct answer. The rewards from this post will remain to sweeten a future pot.
