I believe the second answer choice explanation should say you can't specify generic type on the left hand side in this manner (it currently says right hand side)

[admin]

The right hand side has a problem. It is missing a dot i.e. it should be:
PlaceHolder<String, String> ph2 = PlaceHolder.<String>getDuplicateHolder("b");
instead of
PlaceHolder<String, String> ph2 = PlaceHolder<String>getDuplicateHolder("b");

That is why the explanation says Right hand side.
