I was able to determine which of the multi choice answers was the best match for the question, however I did not consider any of the provided answers accurately reflected was was being asked.
Find the list of all possible distinct destinations, with at most one layover, departing from the base airports of airlines that make part of the “OneWorld” alliance. The airlines should be national carriers from Germany, Spain or Canada only. Include both the destination and which airline services that location. As a small hint, you should find 158 destinations.
Whilst the second leg of all 158 destinations are serviced by routes operated by the national carriers from Germany, Spain or Canada, none of these carriers operated routes from their base to the layover destination. In all cases the passenger would have to use an alternative airline for the first leg, in some cases from an alternative alliance.
I therefore find this lab a bit ambiguous and confusing, by my interpretation of the question none of the answers are correct and the hint of 158 destinations is wrong, I make the total destinations operated by the 3 national carriers from their base as 0.
Is this just me reading the the question wrongly or dose the question/answer need to be amended to remove this ambiguity?
