15 Sam is the driver at fault in a car accident.
Which of the following is covered by Sam’s compulsory third-party (CTP) insurance?
A. Repairs to Sam’s car
B. Injury to the other driver
C. Damage to the other driver’s car
D. Cost of repairing a building damaged in the accident

Are they trying to test if the candidate can logically identify what constitutes a third party? The odd thing to me is the answer appears to be B, C and D. Did they really mean what does it NOT cover?

I'm not familiar with the terms used in Australia but wouldn't it be D? "Third party" implies someone not involved in the accident who suffered a loss, which describes the owner of the building. They were not driving, they were not in a car accident, but their property was damaged as a result of the accident. That's how I would interpret it anyway.

In most English speaking countries the first party is the driver, the second parties are the passengers accompanying the driver, and the third parties are anyone outside the car. That's why drivers are typically required to have third party insurance, to protect anyone not directly involved with the driver.

Very true. There is also a huge difference in "math" math and "applied" math; i.e. between math as a research subject and math as a tool.

This is my opinion:
From my perspective as a Physics major, sometime between being a freshman and being in graduate school, I came to the conclusion that Math is science in it pure abstract form. Physical science is when mathematics is applied to describe/explain the (kind of) physical.
Remember, there is no spoon (just mathematics).
What we think of as physical is pure perception. I am sitting on a chair right now, yet not a single part of my body really "touch" the chair. It is the electro-repulsive force between me and the chair that keeps me from "falling" to the ground.
When we have missing energy (in a consistent way), we think, okay, there is a particle that we haven't yet found that shoot off somewhere. We hypothesis this particle, gave it the right mass, momentum, spin, color, whatever. Geez, now we see that this particle "exist" in some other experiments as well since we found that missing mass, momentum, whatever. Is it real? Color in quantum properties of particles surely is not color as we see in rainbows. But in quantum/particle physics, it is about as real as any other property such as electrical-charge.
We got this extra speed with the orbiting star - there must be some additional mass holding the star in orbit. We'll call it dark matter. We don't see it, it must be there or the star will not be able to be held in orbit at that speed...
So there was no spoon. We found the mathematics to describe what we "saw" and... well... a spoon kind of fit the explanation well.
At some point, the level of abstraction becomes... well strange (it is and it is not not what "Strange" mean in particle physics).
Math is science in its pure abstracted form. Nothing physical until your find some physical phenomenon that can be describe by a set or sets of mathematics.
There is/was a joke about Wolfgang Pauli (the joke is so because Wolfgang Pauli was the undisputed go-to guy with understanding the Fine Structure Constant and Quantum Mechanics): When Pauli got to heaven, he asks God why the Fine Structure Constant is the value we know. God told him why. He then explain to God why that couldn't possibly be right.
If I should be able to ask God questions directly, I would have some math questions for him. But I lack Pauli's expertise in the subject matter and I will have to take God's word for it.

Hmm here it's just called liability insurance, it covers damage and injury to others and their property but not the driver themselves, sounds like it's pretty much the same thing.
