Nice set of questions here.
Interesting is number 7:
Spoilers: The given answer is (b), and the Law quoted is the one saying that a quick throw must be taken behind where the ball goes into touch. I'm glad this backs up a literal interpretation of that law, rather than reading it as "behind where the lineout would be".
It also seems to indicate that, having decided to take a quick throw and had it disallowed, the receiving team have given up the option of taking the scrum or a re-kick, and accepted the kick.
Further question: The law says "accept the kick" rather than "have a lineout", so presumably they could take a (legal) quick throw. But it does also say that the linout is it the halfway line; would anyone read this as not allowing the quick throw?
Interesting is number 7:
7. Morné Klipspringer drops out after the Flightless Birds have scored but the kick goes directly into touch just inside the Flightless Birds 22. Mils Cassowary of the Flightless Birds catches the ball in touch and then runs up towards the half-way line. On his 10-metre line he throws the ball back to Richie Kiwi who is 10 metres behind him and 10 metres in from touch.
You will:
a. let play go on
b. order the Flightless Birds to throw the ball in at a formed line-out
c. offer the Leaping Antelope the option of a scrum or a line-out
d. order a scrum
