Input: Consider Input: Passage: The thorax is a tagma composed of three sections, the prothorax, mesothorax and the metathorax. The anterior segment, closest to the head, is the prothorax, with the major features being the first pair of legs and the pronotum. The middle segment is the mesothorax, with the major features being the second pair of legs and the anterior wings. The third and most posterior segment, abutting the abdomen, is the metathorax, which features the third pair of legs and the posterior wings. Each segment is dilineated by an intersegmental suture. Each segment has four basic regions. The dorsal surface is called the tergum (or notum) to distinguish it from the abdominal terga. The two lateral regions are called the pleura (singular: pleuron) and the ventral aspect is called the sternum. In turn, the notum of the prothorax is called the pronotum, the notum for the mesothorax is called the mesonotum and the notum for the metathorax is called the metanotum. Continuing with this logic, the mesopleura and metapleura, as well as the mesosternum and metasternum, are used. Question: The pleura is made of how many lateral regions?

Output: two


Input: Consider Input: 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?

Output: a patrol squadron of Ottoman frigates and corvettes
