Context and question: Eastern or Canada hemlock (Tsuga canadensis) is another important evergreen needle-leaf conifer that grows along the Appalachian chain from north to south, but is confined to lower elevations than red spruce and the firs. It generally occupies richer and less acidic soils than the spruce and firs and is characteristic of deep, shaded and moist mountain valleys and coves. It is, unfortunately, subject to the hemlock woolly adelgid (Adelges tsugae), an introduced insect, that is rapidly extirpating it as a forest tree. Less abundant, and restricted to the southern Appalachians, is Carolina hemlock (Tsuga caroliniana). Like Canada hemlock, this tree suffers severely from the hemlock woolly adelgid.
What insect is extirpating spruces?
Answer: unanswerable
Context and question: The Book of Concord is the historic doctrinal statement of the Lutheran Church, consisting of ten credal documents recognized as authoritative in Lutheranism since the 16th century. However, the Book of Concord is a confessional document (stating orthodox belief) rather than a book of ecclesiastical rules or discipline, like canon law. Each Lutheran national church establishes its own system of church order and discipline, though these are referred to as "canons."
Beginning in what century was the Book of Concord a central part of the Lutheran Church?
Answer: 16th
Context and question: In 1982, Regis McKenna was brought in to shape the marketing and launch of the Macintosh. Later the Regis McKenna team grew to include Jane Anderson, Katie Cadigan and Andy Cunningham, who eventually led the Apple account for the agency. Cunningham and Anderson were the primary authors of the Macintosh launch plan. The launch of the Macintosh pioneered many different tactics that are used today in launching technology products, including the "multiple exclusive," event marketing (credited to John Sculley, who brought the concept over from Pepsi), creating a mystique around a product and giving an inside look into a product's creation.
Who was brought in to shape the marketing of Macintosh in 1928?
