Doctors are very careful change this sentence into yes no

Yes, you have to capitalize the D in

¨Doctor¨

Explanation:

from the excerpt from the "the dark game" the reader can infer that folke cronholm was spying for the allied nations.

a. "to practice" is the best phrase to complete the sentence.

explanation:
