In the following context, I wonder if you could let me know which choice doesn't work and why:
- When my doctor couldn't ........... my disease after a week of treatment he said to go to better hospital and consult a better doctor as something is really wrong with me. He said so, right in front of me.
Based on dictionary definition, "a" fits the best in this context, but I don't know whether the verb "recognize" works too or not.
Dictionaries, acknowledge that "diagnose" can be used for many things as well as a disease and by opening this thread, I was going to know more bout the usage of these two words specially "recognize".
Added: Cambridge Dictionary has raised the example below:
Doctors are trained to recognize the symptoms of different diseases.
But here it's been said that they were unable to recognize "the symptoms" of diseases and not the "diseases".
