Questions & Answers about Es que había tres avispas en mi cuarto.
Since there were three wasps, why is it había and not habían?
Why use the imperfect había instead of the preterite hubo?
We use the imperfect había here because it describes a background state or an ongoing situation in the past ("there were wasps hanging out in my room"). You would use hubo for a specific completed event that took place, like an accident or a concert (for example, hubo un accidente).
What is the purpose of starting the sentence with Es que?
Es que translates literally to "It is that," but in conversation, it functions like "The thing is..." or "It's just that...". It is a very natural, everyday way to introduce an excuse, a justification, or an explanation for something.
Could I use habitación instead of cuarto here?
Yes, absolutely. Cuarto and habitación both mean "room" or "bedroom" and are used interchangeably in this context. Cuarto is slightly shorter, very colloquial, and widely used across Latin America when referring to one's personal bedroom.
