I am having troubles understanding whether I should add an "S" at the end of a verb or not.
The sentence is: "We are a human company that, through design and engineering, develop automation solutions..."
Should the verb Develop have an "S" added at the end? If the personal pronoun that acts upon the verb is a Third-person-singular, it should, otherwise it shouldn't. However I'm having trouble understanding if the personal pronoun acting upon the verb "develop" is We from "We are a human company" or the inferred it from "a company".
The company (it) > develops solutions...
We > develop solutions...
Which one would be the correct interpretation? Or maybe the sentence should be rewritten to avoid this?
