Scire ubi invenire

Every now and then it is fun to be confronted with an enigma which it is apparently impossible to dismantle into little components and render intelligible, but which shows fissures here and there if one works away at it long enough. The specific enigma I have in mind is a compound enigma, namely the King William's College General Knowledge Paper, which is released annually at New Year's by a British private school. Each set of questions has a common element; last year, for instance, the 14th set was about words that had "Martin" in them.

Last year I solved thirteen, and was on the right track for four, of the enigmas; this time I only solved ten, and was on the right track for eight. I mull over the quiz for days, refraining from consulting any books or other sources for help (except out of curiosity, and then the answer doesn't count). But it is actually intended that one research the answers (as the college's pupils do over their winter holidays), having an inkling where one is likely to find them, rather than know them right off the bat. This is the quiz's motto: Scire ubi aliquid invenire possis ea demum maxima pars eruditionis est; i.e. — if my vague recollection of the translation serves me correctly — the greater part of knowledge is knowing where to seek it. These are the problems that I solved:

1. During the year 1908:
1. who announced T?

2. Who began what by:
5. recalling melancholy inspiration from early evening sights and sounds in a rural churchyard?
6. suggesting that it was generally accepted that a well-heeled loner must be looking for a lady?

5. Travelling from Nordic lands, try unravelling:
1. the eponymous traitor
3 and a misplaced cygnet

7.
1. which language was developed by a Polish opthalmologist?
4. which geographically Scandinavian language is not linguistically Scandinavian?

13.
7. who, in his youth, admitted to cutting down a cherry tree?

14. Within the capital of which member state of the United Nations will you find:
3. that its alright?
10. nothing?
