Student or Learner
Could someone explain to me the correct use of "ONE" in the following sentence (my own) please?
Training and CPD (continue professional development) are one of the key standards set out by the GPhc (General Pharmaceutical Council).
can we use are one of the as I have never seen are before one of the .....
Unless "training and CPD" are considered one thing. In which case they could be "one of the..."
