Question: Men typically wore a toga, and women a stola. The woman's stola differed in looks from a toga, and was usually brightly coloured. The cloth and the dress distinguished one class of people from the other class. The tunic worn by plebeians, or common people, like shepherds and slaves, was made from coarse and dark material, whereas the tunic worn by patricians was of linen or white wool. A knight or magistrate would wear an augusticlavus, a tunic bearing small purple studs. Senators wore tunics with broad red stripes, called tunica laticlavia. Military tunics were shorter than the ones worn by civilians. Boys, up until the festival of Liberalia, wore the toga praetexta, which was a toga with a crimson or purple border. The toga virilis, (or toga pura) was worn by men over the age of 16 to signify their citizenship in Rome. The toga picta was worn by triumphant generals and had embroidery of their skill on the battlefield. The toga pulla was worn when in mourning.[citation needed]
Is there an answer to this question: What garment was worn by male gendered adults to convey their status as a citizen of Rome?

Answer: toga virilis

Question: The new Kievan state prospered due to its abundant supply of furs, beeswax, honey, and slaves for export, and because it controlled three main trade routes of Eastern Europe. In the north, Novgorod served as a commercial link between the Baltic Sea and the Volga trade route to the lands of the Volga Bulgars, the Khazars, and across the Caspian Sea as far as Baghdad, providing access to markets and products from Central Asia and the Middle East. Trade from the Baltic also moved south on a network of rivers and short portages along the Dnieper known as the "route from the Varangians to the Greeks," continuing to the Black Sea and on to Constantinople. Kiev was a central outpost along the Dnieper route and a hub with the east-west overland trade route between the Khazars and the Germanic lands of Central Europe. These commercial connections enriched Rus' merchants and princes, funding military forces and the construction of churches, palaces, fortifications, and further towns. Demand for luxury goods fostered production of expensive jewelry and religious wares, allowing their export, and an advanced credit and money-lending system may have also been in place.
Is there an answer to this question: What was the hub in the north-south overland trade route?

Answer: unanswerable

Question: The oldest method of studying the brain is anatomical, and until the middle of the 20th century, much of the progress in neuroscience came from the development of better cell stains and better microscopes. Neuroanatomists study the large-scale structure of the brain as well as the microscopic structure of neurons and their components, especially synapses. Among other tools, they employ a plethora of stains that reveal neural structure, chemistry, and connectivity. In recent years, the development of immunostaining techniques has allowed investigation of neurons that express specific sets of genes. Also, functional neuroanatomy uses medical imaging techniques to correlate variations in human brain structure with differences in cognition or behavior.
Is there an answer to this question: What type of study uses medical imaging techniques to correlate changes in brain structure?

Answer: neuroanatomy

Question: Not a lot of empirical work on the practices of inter/transnational information and intelligence sharing has been undertaken. A notable exception is James Sheptycki's study of police cooperation in the English Channel region (2002), which provides a systematic content analysis of information exchange files and a description of how these transnational information and intelligence exchanges are transformed into police case-work. The study showed that transnational police information sharing was routinized in the cross-Channel region from 1968 on the basis of agreements directly between the police agencies and without any formal agreement between the countries concerned. By 1992, with the signing of the Schengen Treaty, which formalized aspects of police information exchange across the territory of the European Union, there were worries that much, if not all, of this intelligence sharing was opaque, raising questions about the efficacy of the accountability mechanisms governing police information sharing in Europe (Joubert and Bevers, 1996).
Is there an answer to this question: What did the Schengen Treaty do for policing?

Answer:
formalized aspects of police information exchange across the territory of the European Union
