QUES: Many bird species have established breeding populations in areas to which they have been introduced by humans. Some of these introductions have been deliberate; the ring-necked pheasant, for example, has been introduced around the world as a game bird. Others have been accidental, such as the establishment of wild monk parakeets in several North American cities after their escape from captivity. Some species, including cattle egret, yellow-headed caracara and galah, have spread naturally far beyond their original ranges as agricultural practices created suitable new habitat.
Why have some species spread naturally far beyond their original ranges?

ANS: agricultural practices created suitable new habitat

QUES: Above the sessions exist presbyteries, which have area responsibilities. These are composed of teaching elders and ruling elders from each of the constituent congregations. The presbytery sends representatives to a broader regional or national assembly, generally known as the General Assembly, although an intermediate level of a synod sometimes exists. This congregation / presbytery / synod / general assembly schema is based on the historical structure of the larger Presbyterian churches, such as the Church of Scotland or the Presbyterian Church (U.S.A.); some bodies, such as the Presbyterian Church in America and the Presbyterian Church in Ireland, skip one of the steps between congregation and General Assembly, and usually the step skipped is the Synod. The Church of Scotland has now abolished the Synod.[citation needed]
What exists above the presbyteries?

ANS: unanswerable

QUES: The writer Sherrel W. Stewart's assertion that "most" African Americans have significant Native American heritage, is not supported by genetic researchers who have done extensive population mapping studies. The TV series on African-American ancestry, hosted by the scholar Henry Louis Gates, Jr., had genetics scholars who discussed in detail the variety of ancestries among African Americans. They noted there is popular belief in a high rate of Native American admixture that is not supported by the data that has been collected. (Reference is coming)
What do genetic researches believe most African Americans have?

ANS: unanswerable

QUES: The Sardinian language is considered to be its own Romance language family, separate not only from standard Italian but also the wider Italo-Dalmatian family, and it includes the Campidanese Sardinian and Logudorese Sardinian variants. However, Gallurese, Sassarese, and Corsican are also spoken in Sardinia, and these languages are considered closely related or derived from the Italian Tuscan language and thus are Italo-Dalmatian languages. Furthermore, the Gallo-Romance language of Ligurian and the Catalan Algherese dialect are also spoken in Sardinia.
Where are Romance, Gallurese and Sassarese also spoken?

ANS:
unanswerable
