Excerpt from a backward glance at eighty charles a. murdock my grandfather was the oldest of the brothers. when he married betsy buss his father set aside for him twenty acres of the home farm, and here he built the house in which he lived for forty years, raising a family of ten children. i remember quite clearly my great-grandfather silas hills. he was old and querulous, and could certainly scold; but now that i know that he was born in 1760, and had nineteen brothers and sisters, i think of him with compassion and wonder. it connects me with the distant past to think i remember a man who was sixteen years old when the declaration of independence was signed. he died at ninety-five, which induces apprehension. the passage is most likely from a/an a) biography. b) editorial. c) memoir. d) poem.
