"There you go again," POTUS' pronouns show that if he was talking about "Roads & Bridges" then the statememnt would have said "You didnt build them, or those" etc. Instead, he clearly said "You didnt build THAT." a singular pronoun that when diagrammed reflects to "BUSINESS." Finally Mrs Woods was right. Diagramming sentences paid off!!! Thanks to my my 10th grade English Teacher.
