The document provides examples for using prepositions like "at", "in", and "on" with verbs like "be", "will be", "was", and "have been" to indicate location in Swahili-English translations. It gives question and answer pairs with places like "home", "town", "school", and countries to demonstrate how to ask and answer "where" questions in both languages. Key rules covered are using "at" for specific locations and "in" for larger areas, and selecting the correct verb form based on whether the question is about the present, future or past time.
