In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Question: What country is the island of Samothrace in now? Passage:The sculptor is unknown, although Paul MacKendrick suggests that Pythokritos of Lindos is responsible. When first discovered on the island of Samothrace (then part of the Ottoman Empire and called Semadirek) and published in 1863, it was suggested that the Victory was erected by the Macedonian general Demetrius Poliorcetes after his naval victory at Cyprus, between 295 and 289 BC. The Archaeological Museum of Samothrace continues to follow these originally established provenance and dates. Ceramic evidence discovered in recent excavations has revealed that the pedestal was set up about 200 BC, though some scholars still date it as early as 250 BC or as late as 180. Certainly, the parallels with figures and drapery from the Pergamon Altar (dated about 170 BC) seem strong. The evidence for a Rhodian commission of the statue has been questioned, however, and the closest artistic parallel to the Nike of Samothrace are figures depicted on Macedonian coins. Samothrace was an important sanctuary for the Hellenistic Macedonian kings. The most likely battle commemorated by this monument is, perhaps, the Battle of Cos in 255 BC, in which Antigonus II Gonatas of Macedonia won over the fleet of Ptolemy II of Egypt.

Question: How many viruses are recognized as the type of virus that poliovirus is? Passage:Poliovirus is an enterovirus. Infection occurs via the fecal–oral route, meaning that one ingests the virus and viral replication occurs in the alimentary tract. Virus is shed in the feces of infected individuals. In 95% of cases only a primary, transient presence of viremia (virus in the bloodstream) occurs, and the poliovirus infection is asymptomatic. In about 5% of cases, the virus spreads and replicates in other sites such as brown fat, reticuloendothelial tissue, and muscle. The sustained viral replication causes secondary viremia and leads to the development of minor symptoms such as fever, headache, and sore throat. Paralytic poliomyelitis occurs in less than 1% of poliovirus infections. Paralytic disease occurs when the virus enters the central nervous system (CNS) and replicates in motor neurons within the spinal cord, brain stem, or motor cortex, resulting in the selective destruction of motor neurons leading to temporary or permanent paralysis. In rare cases, paralytic poliomyelitis leads to respiratory arrest and death. In cases of paralytic disease, muscle pain and spasms are frequently observed prior to onset of weakness and paralysis. Paralysis typically persists from days to weeks prior to recovery.

Question: How many years did Major General Haislip serve in the military? Passage:On 15 May 1942, five months after the United States entered World War II, the 85th Infantry Division was ordered into active military service at Camp Shelby, Mississippi, under the command of Major General Wade H. Haislip. Divisions in the U.S. Army at that time were "triangularized" with three combat regiments instead of the four regiment structure "square division" used during World War I. The 340th Infantry Regiment was redesignated as the 410th Quartermaster Battalion and left the division. Basic infantry training was begun in June 1942 at Camp Shelby, Mississippi. In April 1943, it participated in large-scale army training in the Louisiana Maneuvers near Leesville, Louisiana. In August, the division was moved to Camp Coxcomb, California for desert warfare training. In October, the division was transferred to Fort Dix, New Jersey, for final preparations before shipment overseas. Major General John B. Coulter was transferred as commander and retained this position throughout the war. The Assistant Division Commander (ADC) throughout the war was Brigadier General Lee S. Gerow.
