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: Which of the three singles Tamia was nominated for Grammys for in the 40th Annual Grammy Awards had the most sales? Passage:In 1994, Tamia signed her first recording deal with Warner Bros. Records and collaborated with veteran producer Quincy Jones on his album Q's Jook Joint (1995). Their output, the singles "You Put a Move on My Heart" and "Slow Jams", as well as "Missing You", a song Tamia recorded with Brandy, Gladys Knight, and Chaka Khan for the soundtrack of the 1996 motion picture Set It Off, each earned her nominations at the 40th Annual Grammy Awards. She later co-signed with Jones's Qwest Records label, a joint venture with Warner Bros., on which her self-titled debut album was released in 1998. Upon its release, Tamia received a mixed to positive reception by critics and garnered the singer two Juno Award nominations for Best New Solo Artist and R&B/Soul Recording of the Year at the 1999 award ceremony. In addition, it peaked at number sixty-seven on the Billboard 200 chart, selling 416,000 copies in the United States, and was eventually certified gold in Japan for 100,000 copies shipped to stores.

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.

Question: Which river that trappers assembled pack trains at the junction of is longer? Passage:The Bad Pass Trail, also known as the Sioux Trail, was established by Native Americans on the border of present-day Montana and Wyoming as a means of access from the Bighorn Basin in Wyoming to Bison-hunting grounds in the Grapevine Creek area of Montana. Marked by stone cairns, the trail led across Bad Pass and was established in pre-Columbian times. After Europeans arrived in the area it was frequented by fur trappers and mountain men, beginning in 1824. Trappers assembled pack trains at the junction of the Shoshone River and the Bighorn River, using the Bad Pass Trail to avoid Bighorn Canyon. The trail ended at the mouth of Grapevine Creek on the Bighorn, from which the pack train could float down the Bighorn on rafts to the Yellowstone River and then to the Missouri and on to St. Louis.
