About Question enthuware.ocpjp.v21.2.4042 :

[shear12345]

I previously submitted a post saying that the correct answer was missing part of the desired output of the question ("Math"). After going back and reviewing my test again, I noticed that in attempt to fix the correct answer, someone just added "Math" to the strings being added to the subjects collection and didn't remove the erroneous string "Maths" (plural). So the correct answer is still incorrect.

Right. Fixed.
