Is the gate question a trick? H has the brace the wrong way round.

Nope. A piece of wood like that will work in tension or
compression. If you were to use a diagonal wire it would only
work one way.

It isn't the wood, it's the joints. The brace is effectively wedged
between the rails. If it's the wrong way round the joints will pull out.
This is utterly basic.
