As far as I read their comment, @GreenKnight23@lemmy.world did not intend to compare science and religion, but to discuss interview techniques, using geography and religion as examples.

"Is the earth round?" and "Is Jesus real?" are both closed questions that can only be answered with "yes" or "no".

"What is the shape of the earth?" and "Who is Jesus?" are both open questions that call for a statement.

I don't get their argumentation, why open questions are preferable to closed ones because of the first amandement, but agree nonetheless. Closed questions cut off the interviewee and are a very bad interview technique.

Within a couple moves, this knight can land on all squares of this board?

Tbf, that was not only smoke from cigarettes. Combustion engines and furnaces used to add a lot of smoke, too, before the use of catalysators and filters became compulsory.
