TASK DEFINITION: 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.
PROBLEM: Question: What modern day country did the Efe people populate? Passage:In modern times, the creation of relatively simple dome-like structures has been documented among various indigenous peoples around the world. The wigwam was made by Native Americans using arched branches or poles covered with grass or hides. The Efé people of central Africa construct similar structures, using leaves as shingles. Another example is the igloo, a shelter built from blocks of compact snow and used by the Inuit people, among others. The Himba people of Namibia construct "desert igloos" of wattle and daub for use as temporary shelters at seasonal cattle camps, and as permanent homes by the poor. Extraordinarily thin domes of sun-baked clay 20 feet in diameter, 30 feet high, and nearly parabolic in curve, are known from Cameroon.

PROBLEM: Question: Which city is the largest  -  the city near junction K, or the city near junction A? Passage:Belgrade marshalling yard () or Makiš railway station (), or Makiš freight station, is a classification yard of the Belgrade railway junction and the largest railway station in Serbia. It is located in the neighbourhood of Makiš in Čukarica of Belgrade. The railroad continues to Ostružnica in one line via park A, in the other direction to Ostružnica via park B, in third direction to Resnik via junction B near Železnik and junction K of Belgrade railway junction near Petlovo Brdo, in fourth direction to Resnik via junction R in the tunnel below Vidikovac and junction A near Kneževac, in the fifth direction to Rakovica via park B and junction R, in the sixth direction to Rakovica via park A and junction T, in the seventh direction to Rakovica via park B and junction T per second line and the eight towards direction to Jajinci. Belgrade marshalling yard consists of 120 railway tracks.

PROBLEM: Question: How long had Chiyoda Corporation been in business when the Flue-gas desulfurization equipment they helped Black & Veatch design was installed? Passage:During construction of Unit 4, a cooling tower was commissioned by Cincinnati Gas and Electric (CG&E) (a forerunner of Duke Energy) in order to meet pollution control mandates set by the State of Ohio. Its four smokestacks were upgraded with electrostatic precipitators to prevent fly ash from being released into the atmosphere. Stuart was the test site for the Low- Cell Burner (LNCB) designed by Babcock & Wilcox. The LNCB project utilized Unit 4 over a duration of 53 months from 1990–1994. The test confirmed that a LNCB can reduce nitrogen oxide () emissions by more than 50%, but the carbon monoxide (CO) emissions were inconclusive. Each unit at Stuart were retrofitted with selective catalytic reduction (SCR) systems between 2003–2004 by Black & Veatch. The SCRs were installed to comply with the Clean Air Act's 1990 amendments and Ohio's State Implementation Plan (SIP). Flue-gas desulfurization (FGD) equipment, designed by Black & Veatch with assistance from the Chiyoda Corporation was installed at J.M. Stuart in 2008. The FGD equipment reduced 97% of the plant's sulfur dioxide () emissions. In order to support the FGD process, a smokestack was constructed.
