[EX Q]: Val Abbey (Abbey of St Mary of Val) (Abbaye Notre-Dame du Val) was a Cistercian abbey in Meriel and Villiers-Adam in Val-d'Oise, 30 kilometers north of Paris.
[EX A]: To which religious order did Val Abbey belong?

[EX Q]: While Clostridium difficile epidemiology is well documented in many European countries, data are largely missing for South Eastern European region. Here we report the PCR ribotype distribution of 249 C.difficile isolates received for typing from six hospital settings from Croatia, Bosnia and Herzegovina, Republic of Macedonia and Serbia in time period from 2008 to 2015. Twenty-four PCR ribotypes were detected. The majority of strains from Bosnia and Herzegovina and Serbia belonged to PCR ribotype 027 (65.8%). Other three dominating PCR ribotypes were 176 (18 strains; Croatia), 001/072 (15 strains; all countries) and 014/020 (15 strains; all countries).
[EX A]: Which main ribotype of Clostridium difficile is responsible of the recent outbreak?

[EX Q]: Humans evolved during the later Cenozoic. New fossil discoveries alter the details of what we know about the evolution of modern humans, but the major evolutionary path is well understood. Humans evolved from primates, and apes and humans have a primate common ancestor. About 7 million years ago, chimpanzees (our closest living relatives) and humans shared their last common ancestor. Animals of the genus Ardipithecus, living roughly 4 to 6 million years ago, had brains roughly the size of a female chimp. Although they lived in trees, they were bipedal. Standing on two feet allows an organism to see and also to use its hands and arms for hunting. By the time of Australopithecus afarensis, between 3.9 and 2.9 million years ago, these human ancestors were completely bipedal and their brains were growing rapidly (Figure 1.1). Australopithecus afarensis is a human ancestor that lived about 3 million years ago. The genus Homo appeared about 2.5 million years ago. Humans developed the first stone tools. Homo erectus evolved in Africa about 1.8 million years ago. Fossils of these animals show a much more human-like body structure, which allowed them to travel long distances to hunt. Cultures begin and evolve. Homo sapiens, our species, originated about 200,000 years ago in Africa. Evidence of a spiritual life appears about 32,000 years ago with stone figurines that probably have religious significance (Figure 1.2). The ice ages allowed humans to migrate. During the ice ages, water was frozen in glaciers and so land bridges such as the Bering Strait allowed humans to walk from the old world to the new world. DNA evidence suggests that the humans who migrated out of Africa interbred with Neanderthal since these people contain some Neanderthal DNA. Click image to the left or use the URL below.

[EX A]:
the human ancestor, ______________, lived between 3.9 and 2.9 million years ago, was bipedal and had a brain larger than a chimp.
