Task: Question Generation
Input (English): Passage: Old Pine Church is a large, one-story, gablefront log building. Its symmetrical front façade faces west and encompasses a main entrance consisting of a double set of four-paneled doors. The main entrance is reached by two concrete steps, on either side of which is a modern metal handrail. Above the entrance is a small wooden sign painted white reading "Old Pine Church" in black lettering. On either side of the doors are two nine-over-six double-hung sash wooden windows.Placed symmetrically in the north and south sides of the church are two nine-over-six double-hung sash wooden windows. Between the two windows on the church's north elevation is an exterior concrete block chimney. The layout of the east-facing rear elevation of the church is also symmetrical, and features three nine-over-six double-hung sash wooden windows, with the center window placed above and between the other two windows. The church's windows have been repaired using materials consistent with original construction.At the base of each of the church's four corners is a large uncut stone pier. Fieldstones span the church's perimeter foundations, which were added at a later date to discourage intrusion by animals. The original hewn log beams, still retaining bark, can be seen under the church. The church is covered with brown-painted wooden German siding and is crowned by a modern standing-seam metal roof.Architectural historian Sandra Scaffidi states that the simple form and construction of Old Pine Church are indicative of the early settlers' access to materials and are an example of the log construction techniques used in the religious architecture of Hampshire County's earliest settlers. She adds that Old Pine Church is representative of a "simple design and form common to the early ecclesiastical buildings" and an "excellent example of one of the area's early rural church complexes".
Output (English): What is the last name of the person who says that the church is an excellent example of one of the area's early rural church complexes?
