Question: The number of species invasions has been on the rise at least since the beginning of the 1900s. Species are increasingly being moved by humans (on purpose and accidentally). In some cases the invaders are causing drastic changes and damage to their new habitats (e.g.: zebra mussels and the emerald ash borer in the Great Lakes region and the lion fish along the North American Atlantic coast). Some evidence suggests that invasive species are competitive in their new habitats because they are subject to less pathogen disturbance. Others report confounding evidence that occasionally suggest that species-rich communities harbor many native and exotic species simultaneously while some say that diverse ecosystems are more resilient and resist invasive plants and animals. An important question is, "do invasive species cause extinctions?" Many studies cite effects of invasive species on natives, but not extinctions. Invasive species seem to increase local (i.e.: alpha diversity) diversity, which decreases turnover of diversity (i.e.: beta diversity). Overall gamma diversity may be lowered because species are going extinct because of other causes, but even some of the most insidious invaders (e.g.: Dutch elm disease, emerald ash borer, chestnut blight in North America) have not caused their host species to become extinct. Extirpation, population decline, and homogenization of regional biodiversity are much more common. Human activities have frequently been the cause of invasive species circumventing their barriers, by introducing them for food and other purposes. Human activities therefore allow species to migrate to new areas (and thus become invasive) occurred on time scales much shorter than historically have been required for a species to extend its range.

Question: The popularization of the Jewish chant may be found in the writings of the Jewish philosopher Philo, born 20 BCE. Weaving together Jewish and Greek thought, Philo promoted praise without instruments, and taught that "silent singing" (without even vocal chords) was better still. This view parted with the Jewish scriptures, where Israel offered praise with instruments by God's own command (2 Chronicles 29:25). The shofar is the only temple instrument still being used today in the synagogue, and it is only used from Rosh Chodesh Elul through the end of Yom Kippur. The shofar is used by itself, without any vocal accompaniment, and is limited to a very strictly defined set of sounds and specific places in the synagogue service.

Answer: Philo
Question: Like Finnish, Estonian employs the Latin script as the basis for its alphabet, which adds the letters ä, ö, ü, and õ, plus the later additions š and ž. The letters c, q, w, x and y are limited to proper names of foreign origin, and f, z, š, and ž appear in loanwords and foreign names only. Ö and ü are pronounced similarly to their equivalents in Swedish and German. Unlike in standard German but like Finnish and Swedish (when followed by 'r'), Ä is pronounced [æ], as in English mat. The vowels Ä, Ö and Ü are clearly separate phonemes and inherent in Estonian, although the letter shapes come from German. The letter õ denotes /ɤ/, unrounded /o/, or a close-mid back unrounded vowel. It is almost identical to the Bulgarian ъ /ɤ̞/ and the Vietnamese ơ, and is used to transcribe the Russian ы.

Answer: Finnish
Question: Dams remain the principal source of water both for domestic and agricultural use; Cyprus has a total of 107 dams (plus one currently under construction) and reservoirs, with a total water storage capacity of about 330,000,000 m3 (1.2×1010 cu ft). Water desalination plants are gradually being constructed to deal with recent years of prolonged drought. The Government has invested heavily in the creation of water desalination plants which have supplied almost 50 per cent of domestic water since 2001. Efforts have also been made to raise public awareness of the situation and to encourage domestic water users to take more responsibility for the conservation of this increasingly scarce commodity.
Try to answer this question if possible: What is the capacity of water that the dams on Cyprus can hold?
Answer:
330,000,000 m3 (1.2×1010 cu ft).
