In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

[EX Q]: Question: How long was the Nazi Party around for before Stahlecker joined it? Passage:On 1 May 1932, Stahlecker joined the Nazi Party (no. 3,219,015) as well as the SS (no. 73,041). On 29 May 1933, he was appointed deputy director of the Political Office of the Wurttemberg State Police. In 1934, he was appointed head of the Gestapo in the German state of Wurttemberg and soon assigned to the main office of the Sicherheitsdienst (SD). On 11 May 1937, he became head of the Gestapo in Breslau. After the incorporation of Austria in 1938, Stahlecker became SD chief of the Danube district (Vienna), a post he retained even after being promoted to SS-Standartenfuhrer. In the summer of 1938, Stahlecker became Inspector of the Security Police in Austria, succeeding Gestapo chief Heinrich Muller in that position. As of 20 August 1938, Stahlecker was the formal head of the Central Agency for Jewish Emigration in Vienna, though its de facto leader was Adolf Eichmann. Differences of opinion with Reinhard Heydrich motivated Stahlecker to move to the Auswartiges Amt (Foreign Office), after which he held posts as the commander of the Security Police and SD in the Protectorate of Bohemia and Moravia under SS-Brigadefuhrer Karl Hermann Frank. In mid-October 1939, Eichmann and Stahlecker decided to begin implementation of the Nisko Plan.

[EX Q]: Question: How many people died in the incident that contaminated about 30,000 km? Passage:Natural strontium is a mixture of four stable isotopes: Sr, Sr, Sr, and Sr. Their abundance increases with increasing mass number and the heaviest, Sr, makes up about 82.6% of all natural strontium, though the abundance varies due to the production of radiogenic Sr as the daughter of long-lived beta-decaying Rb. Of the unstable isotopes, the primary decay mode of the isotopes lighter than Sr is electron capture or positron emission to isotopes of rubidium, and that of the isotopes heavier than Sr is electron emission to isotopes of yttrium. Of special note are Sr and Sr. The former has a half-life of 50.6days and is used to treat bone cancer due to strontium's chemical similarity and hence ability to replace calcium. While Sr (half-life 28.90years) has been used similarly, it is also an isotope of concern in fallout from nuclear weapons and nuclear accidents due to its production as a fission product. Its presence in bones can cause bone cancer, cancer of nearby tissues, and leukemia. The 1986 Chernobyl nuclear accident contaminated about 30,000km with greater than 10 kBq/m with Sr, which accounts for 5% of the core inventory of Sr.

[EX Q]: Question: Who owned the company for which Smith recorded the first version of "Dial That Telephone"? Passage:She married comedian, songwriter and record producer John Laurence Criner (19141992), and recorded several songs with Johnny Otis for the G&G and Gem labels, both parts of Criner's Royal Records group. She also recorded for Miltone Records in 1947, one of her songs being an answer record to label owner Roy Milton's own "R.M. Blues". During the 1950s, she recorded a number of tracks for Aladdin Records, including in 1953 the first version of "Dial That Telephone", a comedic monologue in which she complains to a friend about the absence of her husband. She also recorded with Ike Carpenter's orchestra. In 1955 and 1956, she recorded several tracks including "Champagne Mind With A Soda Water Income" with the Squires, a vocal group featuring Don Harris and Dewey Terry (later Don and Dewey). She recorded several versions of "Dial That Telephone" over the years, including a 1959 version released on Criner's Spot record label. However, the song only became a chart success in 1965, when a new recording on the Duo Disc label reached #36 on the Billboard R&B chart. In 1968, her recording of "Harper Valley P.T.A. Gossip", a spoken elaboration of the content of Jeannie C. Riley's hit "Harper Valley PTA", reached #43 on the R&B chart.
