FAQ: Introducing the Reason in a Presentation Practice Reply

1. Can I start my reply with “because”?

Yes, but only in informal settings. In formal presentations, it is better to start with a full sentence like “The reason is that…” to sound more complete.

2. What if I have more than one reason?

List them clearly. Use “first,” “second,” or “also” to separate them. For example: “The first reason is cost. The second reason is time.”

3. Is it okay to use “due to” at the beginning of a sentence?

Yes, but be careful with grammar. “Due to” should be followed by a noun or noun phrase. For example: “Due to the delay, we rescheduled.” Do not say “Due to we delayed.”

4. How do I avoid sounding like I am making an excuse?

Focus on facts, not feelings. Instead of saying “I’m sorry, but the reason is…,” say “The reason is based on the data we collected.” This sounds objective and professional.
