I got that one ‘wrong’ too. Ugly construction of question, not entirely correct, and very outdated. The rationale is to connect all the adjectives that describe the noun ‘train pass’. Which contains another adjective - ‘train’. So why didn’t they hyphenate ‘train’ and ‘pass’? I wouldn’t call their ‘correct’ choice as normal usage here in Aus. Maybe hyphenate ‘twenty-four’ cos this functions as a single word but the ‘hour’ surely doesn’t need it for clarity any more than ‘train-pass’ does. Bad question really.

Question 3 is deliberately misleading and wrong. It should be ‘24 hour ticket’. I wouldn’t hyphenate at all (see Goonsey) and no-one writes out time like that. In fact the classic “elements of style” which is a writing bible says you should use numerals for numbers greater or equal to 10 and write them out in words less than that.

That question is some stupid twat adult getting their kicks by making 14 year olds squirm. Or an adult who doesn’t know their grammar.

Australia doesn’t hyphenate, nasty American habit.
