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.

Question: 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 50.6 days and is used to treat bone cancer due to strontium's chemical similarity and hence ability to replace calcium. While Sr (half-life 28.90 years) 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 30,000 km with greater than 10 kBq/m with Sr, which accounts for 5% of the core inventory of Sr.
 Links: a. Rubidium b. Mass number c. Electron capture d. Chernobyl disaster

Question: Question: How old was Stephen Fry when "Me and My Girl" was revised for production at the Leicester Haymarket Theatre? Passage:The musical was revived in 1941, 1945 and 1949 on the West End. Lupino Lane starred and directed each of these productions, with choreography by Fred Leslie. In 1984, a revised production opened at the Leicester Haymarket Theatre with a revised script by Stephen Fry and contributions by director Mike Ockrent. It transferred to the Adelphi Theatre on 12 February 1985 and closed on 16 January 1993 after an eight-year run and 3,303 performances. It starred Robert Lindsay as Bill Snibson, Emma Thompson and Frank Thornton. The production won two Olivier Awards: Musical of the Year and Outstanding Performance by an Actor in a Musical (Robert Lindsay). Cast changes included Enn Reitel as Bill and Su Pollard as Sally in 1986; Gary Wilmot as Bill and Jessica Martin as Sally in 1989. Thornton was succeeded by Nicholas Smith. The production subsequently toured throughout Britain.

Question: Question: What is the birthplace of the person who sang "Loyalty"? Passage:American rapper Tyga has released seven studio albums, three compilation albums, nineteen mixtapes, seventy-four singles (including thirty-four as a featured artist) and forty-six music videos. In 2008, Tyga released his first studio album, No Introduction, on the record label Decaydance Records. The album featured the single "Coconut Juice", which features singer Travie McCoy; the song peaked at number 94 on the US Billboard Hot 100, becoming Tyga's first song to appear on the chart. In 2010, Tyga and American singer Chris Brown released the collaborative mixtape Fan of a Fan, which included the single "Deuces": the song peaked at number 14 on the Billboard Hot 100 and became Tyga's first song to chart on the US Hot R&B/Hip-Hop Songs chart, peaking at number one. Tyga also appeared on the song "Loyalty", a single by fellow rapper Birdman, and collaborated with rapper Lil Wayne on the non-album single "I'm on It", both of which failed to chart on the Billboard Hot 100.
 Links: a. DCD2 Records b. Deuces (song) c. Birdman (rapper) d. Travie McCoy
