I can't understand what all the fuss is about here, but I didn't see the deleted postings. The questions asked in the original postings are quite straightforward (although I don't know all the answers).

1. Flag answers above are accurate. I heard it as symbolising peace and harmony between the two traditions represented by Green and Orange.

2. The harp is the symbol that appears on the Irish coat of arms. The shamrock appears as a symbol in other locations, most notably on Irish sports shirts (still on Rugby, but replaced by a logo on the soccer shirt).

3. Cead Mile failte looks right, but I regard it as a greeting rather than a 'proverb' as such.

4. Amhrán na bhFiann is as Bonnie says is the National anthem and should be played at all official gatherings etc. As far as I know it should officially be played at the start of proceedings, but it is often left to the end as a wrap up to the night.

5. I haven't ridden a bike in years, but I did so as a kid and never remember anyone telling me to stop it on any particular day. Given the relative recence of the invention of the bicycle I can't see how it could be related to an ancient tradition. The short answer here is I don't know!

6. The Emerald Isle is a nickname for Ireland. The country was also known as the Island of Saints and Scholars, because of the work that Irish monks did in restoring christianity to Europe afer the dark ages in the 6th to 8th centuries. I don't think the term Scientist would have been in common use back then. Neither is an official second name. I don't know what the question setter intended but I suspect The Emerald Isle is the right answer because the other one is slightly innaccurate?
