Allow me to introduce Mr. and Mrs [period] Weathers from Detroit. 

Ms. Sarah Davis is the president of Gitmore Ltd [period] and a good friend of Maj. Williams. [I believe Maj. is short for Major, as in an army position, so I think that is correct, unless the teacher is implying this person's name is "Maj", which would be weird.]

Will Dr [period] Johnson be telling us about his mission to the UN? [I wasn't sure if UN should have periods, but no where on their website un.org do they use them, so I believe this is correct.]
