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.

Question: How big is the county that PA 741 begins in? Passage:PA 741 begins at an intersection with PA 722 in the borough of East Petersburg in Lancaster County, heading to the south on two-lane undivided Lemon Street, which is unsigned and locally maintained. The road passes homes prior to crossing into East Hempfield Township, where it becomes Rohrerstown Road and continues through industrial parks. PA 741 gains a center left-turn lane and becomes signed at the Commercial Avenue intersection. The route continues to an interchange with PA 283, at which point it becomes state-maintained. The road crosses the Little Conestoga Creek into Manheim Township after PA 283. The route becomes two lanes again and turns east prior to turning southwest and crossing the Little Conestoga Creek back into East Hempfield Township. At this point, PA 741 becomes McGovernville Road and comes to a bridge over Norfolk Southern's Lititz Secondary and Amtrak's Keystone Corridor. The road passes a mix of homes and woods as it comes to the Harrisburg Pike intersection, where it makes a turn to the south onto Rohrerstown Road, a three lane road with a center left-turn lane. PA 741 passes homes to the west and a branch of Lancaster General Hospital to the east prior to coming to the US 30 interchange. In the area of the interchange, PA 741 is briefly a divided highway. Following US 30, the route becomes a two-lane undivided road and passes residences prior to crossing Norfolk Southern's Columbia Secondary and entering the residential and commercial community of Rohrerstown. Here, PA 741 crosses PA 23. After leaving Rohrerstown, the road passes a mix of farms and businesses prior to an intersection with PA 462.

Todd Mohney, the band's guitarist at the time, left and was replaced by Chris Chasse and began the recording of their new album Siren Song of the Counter Culture. Siren Song of the Counter Culture was released on August 10, 2004 peaking at number 136 on the Billboard 200 album charts, gaining the band major critical and commercial success with the singles "Give It All, "Swing Life Away", and "Life Less Frightening".
