This is obviously a USA quiz, because as per the engine question, it also reckons the GTI had a 1.6 8v engine option, which it didn't in the UK.
"3. What engine variants did the MKII/A2 Golf/GTi's came in?
Your Answer: 1.6L 8-valve; 1.8L 8-Valve & 16-Valve; 2.0L 16-Valve; 1.8L G60"
And question 1 is obviously just a case of the USA getting the GTI a year later than we did.
