Problem: Unicode:

The Consortium first published The Unicode Standard (ISBN 0-321-18578-1) in 1991 and continues to develop standards based on that original work. The latest version of the standard, Unicode 8.0, was released in June 2015 and is available from the consortium's website. The last of the major versions (versions x.0) to be published in book form was Unicode 5.0 (ISBN 0-321-48091-0), but since Unicode 6.0 the full text of the standard is no longer being published in book form. In 2012, however, it was announced that only the core specification for Unicode version 6.1 would be made available as a 692-page print-on-demand paperback. Unlike the previous major version printings of the Standard, the print-on-demand core specification does not include any code charts or standard annexes, but the entire standard, including the core specification, will still remain freely available on the Unicode website.

When was the latest version, Unicode 8.0, released?

A: June 2015

Problem: Sexual orientation:

Gay and lesbian people can have sexual relationships with someone of the opposite sex for a variety of reasons, including the desire for a perceived traditional family and concerns of discrimination and religious ostracism. While some LGBT people hide their respective orientations from their spouses, others develop positive gay and lesbian identities while maintaining successful heterosexual marriages. Coming out of the closet to oneself, a spouse of the opposite sex, and children can present challenges that are not faced by gay and lesbian people who are not married to people of the opposite sex or do not have children.

What is a possible scenario that can occur when a closeted homosexual is in a heterosexual relationship?
---
A: hide their respective orientations from their spouses

Problem: Old English:

Modern editions of Old English manuscripts generally introduce some additional conventions. The modern forms of Latin letters are used, including g in place of the insular G, s for long S, and others which may differ considerably from the insular script, notably e, f and r. Macrons are used to indicate long vowels, where usually no distinction was made between long and short vowels in the originals. (In some older editions an acute accent mark was used for consistency with Old Norse conventions.) Additionally, modern editions often distinguish between velar and palatal c and g by placing dots above the palatals: c, g. The letter wynn is usually replaced with w, but sc, eth and thorn are normally retained (except when eth is replaced by thorn).

What conventional letter from the Latin alphabet typically replaces the wynn from Old English?
---
A: w

Problem: Estonia:

Estonia's constitution guarantees freedom of religion, separation of church and state, and individual rights to privacy of belief and religion. According to the Dentsu Communication Institute Inc, Estonia is one of the least religious countries in the world, with 75.7% of the population claiming to be irreligious. The Eurobarometer Poll 2005 found that only 16% of Estonians profess a belief in a god, the lowest belief of all countries studied (EU study). According to the Lutheran World Federation, the historic Lutheran denomination remains a large presence with 180,000 registered members.

What percentage of Estonians claim no religion?
