I'll take the horse-sized duck. That sounds like it'd pose no threat to me, because it'd be a very cumbersome creature that would struggle to stand up straight .

(The problem with the horse-sized duck, or any oversized fantasy creature, is that it falls foul of the Square-Cube Law. To give an example: if we imagine "a superhuman that is 10 times the size of a regular human", then it'll have 1000 times the mass of a regular human, but only 100 times the muscular strength. Therefore, the superhuman will have only one-tenth of the power-to-weight ratio of a regular human, so it won't be able to do many of the things that a regular human can)

Never thought of it like this before.

Would you rather drive a restored classic car or a luxury sedan?

The luxury sedan.

I'd be too afraid of crashing the restored classic, and wasting the effort of all the volunteers who invested a lot of time into restoring it :'( . 

What's the meaning of this?

It is a word used to indicate the specific thing that has just been mentioned. (For example, after mentioning your question, I could go on to talk about "this question"  )
