Extract the answer to the question from the following context. Question: Who created the laws in Roman times? Context: The legal status of Roman citizenship was limited and was a vital prerequisite to possessing many important legal rights such as the right to trial and appeal, to marry, to vote, to hold office, to enter binding contracts, and to special tax exemptions. An adult male citizen with the full complement of legal and political rights was called "optimo jure." The optimo jure elected their assemblies, whereupon the assemblies elected magistrates, enacted legislation, presided over trials in capital cases, declared war and peace, and forged or dissolved treaties. There were two types of legislative assemblies. The first was the comitia ("committees"), which were assemblies of all optimo jure. The second was the concilia ("councils"), which were assemblies of specific groups of optimo jure.

Extract the answer to the question from the following context. Question: Who makes a good pair? Context: A further example is the goby fish, which sometimes lives together with a shrimp. The shrimp digs and cleans up a burrow in the sand in which both the shrimp and the goby fish live. The shrimp is almost blind, leaving it vulnerable to predators when outside its burrow. In case of danger the goby fish touches the shrimp with its tail to warn it. When that happens both the shrimp and goby fish quickly retreat into the burrow. Different species of gobies (Elacatinus spp.) also exhibit mutualistic behavior through cleaning up ectoparasites in other fish.

Extract the answer to the question from the following context. Question: What were the benefits for the people during Nasser's reign? Context: Nasser made Egypt fully independent of British influence, and the country became a major power in the developing world under his leadership. One of Nasser's main domestic efforts was to establish social justice, which he deemed a prerequisite to liberal democracy. During his presidency, ordinary citizens enjoyed unprecedented access to housing, education, jobs, health services and nourishment, as well as other forms of social welfare, while feudalistic influence waned. By the end of his presidency, employment and working conditions improved considerably, although poverty was still high in the country and substantial resources allocated for social welfare had been diverted to the war effort.
