I have applied to become an Australian commercial pilot and on their website they have a practice psychometric assessment page where you can try out the type of questions they will give you. the website is below:

On page 2, statement number one regarding the first passage appears (to me) to be undeniably true, yet the leaflet says the said statement cannot be determined as true or untrue. What do you guys think? Is there something I am missing here regarding the terms 'economic' and 'economical'? The thing obviously compares long term costs between the two power stations as a big economical difference, therefore making the first statement true and not the answer of "you cannot tell without more information," which the website says it is.
thanks for the input

IMO answer is C:
Due to various reasons, although building a nuclear plant is expensive but if you look at the environmental effects and other core processes its efficiency far exceeds the efficiency of Fossil Fuels.
The Problem with Nuclear plant is the decommissioning process, it requires complex tools and a very big area to dispose the uranium, but if you make the process simpler and less costly the Nuclear energy which is cleaner will easily overtake the Fossil Fuel one.

The economic advantage does include the cost of environmental pollution and the output provided by the plant.


hope i cleared things up a bit.

Yeah, thanks.
I see now that the passage refers to the economical differences, but does not compare them with any other differences, so from the info i cant say that the main difference is economical, because no other differences have been identified.
