See how you do against the USPTO. Can you correctly identify the ends of the cable (it is a single cable 3)? This is “complex” stuff. And this is what patent professionals have to deal with every day - arguing with a government representative whether their interpretation is reasonable.

To help, here are some definitions from the dictionary (Merriam Websters):

1a : the part of an area that lies at the boundary
b(1) : a point that marks the extent of something
(2) : the point where something ceases to exist world without end
c : the extreme or last part lengthwise : tip
d : the terminal unit of something spatial that is marked off by units
e : a player stationed at the extremity of a line or team (as in football)

Choices are (the highlighted circles each have a label - A, B, or C):

A + B

B + C
