Our research question for this topic was the following: How did trench warfare spark inventions and innovations in weaponry from the beginning of the first world war till the end?
We believed that this was a good research question because it was specific and time bound. It clearly states the topic of our project: inventions and innovations in weaponry. It clearly states the timeline of our project: the duration of the first world war.
This research question can also be easily answered, but since it is not a ‘yes-no’ question it opens a large amount of possibilities for sub questions or other aspects to research.
