“At Least One”

Hi, I understand that “at least one” signifies both sufficient and necessary. However, I am having a bit of trouble understanding why we could not have G-MST and L-MST. Is the reason for this that we need to include all elements? It’s possible I overlooked this but my understanding was “at least one” requires MS in one park but does not limit it to one and we could have a case where there are two. A more thorough explanation on this would be very helpful. Thank you!

I.e. answer to Question 16

@DBertaux, happy to help!

The phrase "at least one" does allow for the possibility that there exists more than one. In this game, it is possible for both parks to have an arrangement of MST. This is discussed in our second hypothetical during the game setup, in question #14, and in question #16.

In other words, this is a valid possible scenario:

Does that make sense? Hope it helps! Please let us know if you have any other questions!
