Here is a question about this article: The ancestors of modern bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago. For about 3 billion years, most organisms were microscopic, and bacteria and archaea were the dominant forms of life. In 2008, fossils of macroorganisms were discovered and named as the Francevillian biota. Although bacterial fossils exist, such as stromatolites, their lack of distinctive morphology prevents them from being used to examine the history of bacterial evolution, or to date the time of origin of a particular bacterial species. However, gene sequences can be used to reconstruct the bacterial phylogeny, and these studies indicate that bacteria diverged first from the archaeal/eukaryotic lineage. Bacteria were also involved in the second great evolutionary divergence, that of the archaea and eukaryotes. Here, eukaryotes resulted from the entering of ancient bacteria into endosymbiotic associations with the ancestors of eukaryotic cells, which were themselves possibly related to the Archaea. This involved the engulfment by proto-eukaryotic cells of alphaproteobacterial symbionts to form either mitochondria or hydrogenosomes, which are still found in all known Eukarya (sometimes in highly reduced form, e.g. in ancient "amitochondrial" protozoa). Later on, some eukaryotes that already contained mitochondria also engulfed cyanobacterial-like organisms. This led to the formation of chloroplasts in algae and plants. There are also some algae that originated from even later endosymbiotic events. Here, eukaryotes engulfed a eukaryotic algae that developed into a "second-generation" plastid. This is known as secondary endosymbiosis.
What is the answer to this question: When did the first antecedents of bacteria appear on Earth?

So... 4 billion years ago

Here is a question about this article: The first English coffeehouse opened in Oxford in 1650. Brian Cowan said that Oxford coffeehouses developed into "penny universities", offering a locus of learning that was less formal than structured institutions. These penny universities occupied a significant position in Oxford academic life, as they were frequented by those consequently referred to as the "virtuosi", who conducted their research on some of the resulting premises. According to Cowan, "the coffeehouse was a place for like-minded scholars to congregate, to read, as well as learn from and to debate with each other, but was emphatically not a university institution, and the discourse there was of a far different order than any university tutorial."
What is the answer to this question: According to Brian Cowan, was learning more or less formal in coffehouses as opposed to private institutions?

So... less

Here is a question about this article: The Northern Russian dialects and those spoken along the Volga River typically pronounce unstressed /o/ clearly (the phenomenon called okanye/). Besides the absence of vowel reduction, some dialects have high or diphthongal /e~i/ in the place of Proto-Slavic *e and /o~u/ in stressed closed syllables (as in Ukrainian) instead of Standard Russian /e/ and /o/. An interesting morphological feature is a post-posed definite article -to, -ta, -te similarly to that existing in Bulgarian and Macedonian.
What is the answer to this question: What is okanye?

So...
pronounce unstressed /o/ clearly
