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.

I agree with that but any gates i've built always use the diagonal in
compression.
For one thing the weight of the gate tends to tighten the diagonal against
its fixing points not loosen them and thereby dropping.

Whether the brace is the best way or not it's more resistant to wilt than the others, so it's the answer.

A lot of simple questions really, though a few seemingly ambiguous ones that require an extra moment of thought.
