Definition
Plain language
A question that needs two facts you can look up separately and then compare.
As stated in the literature
In multi-hop question answering, a question whose required facts are independent and can be retrieved in any order, unlike a bridge question's sequentially dependent hops.
Also called: comparison questions
Why it matters: Recognizing this type tells a system it can gather the needed facts independently and in any order, rather than one strictly after another.
For example, 'Which is taller, the Eiffel Tower or the Statue of Liberty?' lets you look up each height separately and then compare them.
