Article: This effectively means that populations of organisms must have reached a certain measurable level of difference to be recognised as subspecies. Dean Amadon proposed in 1949 that subspecies would be defined according to the seventy-five percent rule which means that 75% of a population must lie outside 99% of the range of other populations for a given defining morphological character or a set of characters. The seventy-five percent rule still has defenders but other scholars argue that it should be replaced with ninety or ninety-five percent rule.

Question: The 75% rule states how much of a population must lie outside the range of other populations for a defining set of characters?
Ans: 99%

Article: Carnival is known as Crop Over and is Barbados's biggest festival. Its early beginnings were on the sugar cane plantations during the colonial period. Crop over began in 1688, and featured singing, dancing and accompaniment by shak-shak, banjo, triangle, fiddle, guitar, bottles filled with water and bones. Other traditions included climbing a greased pole, feasting and drinking competitions. Originally signaling the end of the yearly cane harvest, it evolved into a national festival. In the late 20th century, Crop Over began to closely mirror the Trinidad Carnival. Beginning in June, Crop Over runs until the first Monday in August when it culminates in the finale, The Grand Kadooment.

Question: What activity is done using a greased pole?
Ans: climbing

Article: 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).

Question: What Latin letter is used in place of the Old English long S?
Ans: s
