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.

Input: Consider Input: Question: When was the Bronze age? Passage:It was first studied by Lorraine Copeland and Peter Wescombe in 19651966. A wide variety of materials were recovered from the site and its immediate area that are now held in the Saint Joseph University in Beirut. Stone tools from the surface included numerous short, wide, sickle blades with fine denticulation or nibbling along with tanged arrowheads, scrapers, chisels, axes, burins, obsidian and a small green stone axe. Pottery resembled middle periods at Byblos and coloured similar to at Ard Tlaili with red or black washes. Both fine and coarse shards were found of jars with a variety of collared and flared necks and flat bases along with bow rims such as those found at Jericho. Vessels were decorated with stabbed and incised designs, finger pressed around the rim and smoothed by hand or with straw. A painted lattice pattern was detected on at least one piece. Comparisons were made with middle and late Neolithic periods at Byblos showing inhabitation from several phases. The site was also used in Bronze Age and Classical times and material from these phases has been found over a wide area around the site.

Input: Consider Input: Question: Who did Bruce Herschenohn run against in his primary? Passage:In 1992 four-term incumbent Democratic Senator Alan Cranston retired, creating an open seat contest. In what was billed as the "Year of the Woman", Boxer beat fellow Rep. Mel Levine and Lieutenant Governor Leo McCarthy in the Democratic primary, winning 44% of the vote. In the general election, Boxer defeated Republican Bruce Herschensohn, a conservative television political commentator from Los Angeles, by 4.9%. A last-minute revelation that Herschensohn had attended a strip club at least partially affected the outcome. In 1998, she won a second term, beating sitting California State Treasurer Matt Fong by 10.1% of the vote. After facing no primary opposition in the 2004 election, Boxer defeated GOP candidate Bill Jones, the former California Secretary of State, by 20%. In 2010, Boxer defeated GOP candidate Carly Fiorina, former chief executive officer of Hewlett-Packard, by 10%.
Links: a. 1992 United States Senate election in California b. Bruce Herschensohn c. Bill Jones (California politician) d. Leo T. McCarthy

Output: b

Input: Consider Input: Question: What number President was Grover Cleveland before losing in 1888? Passage:Beginning with the 2000 election, the status of the Missouri bellwether came into question. Between 1904 and 2004, Missouri was carried by the victor of each presidential election, with the exception of 1956. Though Bush won the presidency in the 2000 election through the Electoral College, he lost the national popular vote. The 2000 election was unique because this was the first time in over a century where the popular vote winner lost the general election. (In 1888, Missouri voted for Grover Cleveland, the incumbent Democrat, who lost to Republican candidate Benjamin Harrison). Thus, controversy exists as to whether or not Missouri accurately predicted victor in this election. In the subsequent election, Missouri voted for George W. Bush, who this time won both the popular vote and the Electoral College. Missouri has voted reliably Republican since 2000. The state voted for John McCain in 2008, and for Mitt Romney in 2012, both of whom lost the general election to Barack Obama. The controversy is further complicated by the 2016 presidential election, where Missouri voted for Donald Trump by a landslide, while Hillary Clinton won the popular vote by nearly three million votes, but like in 2000, Trump won the Electoral College and became 45th President of the United States. Like 2000, political scientists have differing opinions on whether or not Missouri accurately predicted the victor, and even if Missouri is still a bellwether state at all.
