PROBLEM: Passage: The Russians sent a fleet to Sinop in northern Anatolia. In the Battle of Sinop on 30 November 1853 they destroyed a patrol squadron of Ottoman frigates and corvettes while they were anchored in port. Public opinion in the UK and France was outraged and demanded war. Sinop provided the United Kingdom and France with the casus belli ("cause for war") for declaring war against Russia. On 28 March 1854, after Russia ignored an Anglo-French ultimatum to withdraw from the Danubian Principalities, the UK and France formally declared war. Question: While anchored in the port, what did the Russians destroy?

SOLUTION: a patrol squadron of Ottoman frigates and corvettes

PROBLEM: Passage: Like the Pagan Empire, Ava, Hanthawaddy and the Shan states were all multi-ethnic polities. Despite the wars, cultural synchronisation continued. This period is considered a golden age for Burmese culture. Burmese literature "grew more confident, popular, and stylistically diverse", and the second generation of Burmese law codes as well as the earliest pan-Burma chronicles emerged. Hanthawaddy monarchs introduced religious reforms that later spread to the rest of the country. Many splendid temples of Mrauk U were built during this period. Question: Who is the monarch that has some of the most impressive built in their honor in the Myanmar

SOLUTION: Mrauk U

PROBLEM: Passage: Ctenophora (/tnfr/; singular ctenophore, /tnfr/ or /tinfr/; from the Greek kteis 'comb' and phero 'carry'; commonly known as comb jellies) is a phylum of animals that live in marine waters worldwide. Their most distinctive feature is the 'combs' groups of cilia which they use for swimming they are the largest animals that swim by means of cilia. Adults of various species range from a few millimeters to 1.5 m (4 ft 11 in) in size. Like cnidarians, their bodies consist of a mass of jelly, with one layer of cells on the outside and another lining the internal cavity. In ctenophores, these layers are two cells deep, while those in cnidarians are only one cell deep. Some authors combined ctenophores and cnidarians in one phylum, Coelenterata, as both groups rely on water flow through the body cavity for both digestion and respiration. Increasing awareness of the differences persuaded more recent authors to classify them as separate phyla. Question: What does the ctenophora use to swim?

SOLUTION:
'combs' groups of cilia
