Question

My mom says that since she has her Ph.D. now, I should call her doctor Patterson.

What change should be made to correct this sentence?
lowercase the D in Ph.D.
lowercase Ph.D.
capitalize doctor
capitalize mom

Answer 1

Capitalize doctor because now it refers to a proper noun, Doctor Patterson.

Answer 2

capitalize doctor

Step-by-step explanation:

The acronym "Ph.D" is written correctly in the excerpt shown in the question, although the same can not be said of the word "doctor". The correct one is that the first letter of "doctor" is capital, because this word is referring to a proper name. In this way, we can conclude that the right one would be "Doctor Patterson".
