Hi mate,
That's a shame about your result but 70% was not far off so you have done well so far at least you didn't get 30%
As for your questions if I recall correctly there are 4 answers to choose from on the question relating to the carriage of a dog. The correct answer in your case would have been a) as in CAR 256A it states "the operator of an aircraft may permit a live animal to be in the aircraft only if:
A) the animal is in a container and is carried in accordance with this regulation; or
the animal is carried with the written permission of CASA and in accordance with any conditions specified in the permission.
The answer you chose was referring to the carriage of a dog who is accompanying a visually or hearing impaired person (guide dog) in which case the guide dog must be carried in the passenger cabin and restrained on a moisture absorbent mat so that it may not leave the mat.
Basically unless it's a guide dog, put it in a cage.
As for smoking in an aircraft it is only prohibited on take off, landing,refuelling or when there is a sign indicating that smoking is prohibited at all times on an aircraft.
So to simplify for you if there's a permanent no smoking sign you can't smoke and the pilot has to use the no smoking annunciator during take off landing and refueling. If there isn't a sign up you can't smoke on take off, landing or refueling or if the no smoking light comes on or if there is a sign stating a time during the flight you can't smoke.
Hope this helps you out mate
Best of luck you'll get there next time
