Problem: Spanish language in the United States:

Calvin Veltman undertook, for the National Center for Education Statistics and for the Hispanic Policy Development Project, the most complete study of English language adoption by Hispanophone immigrants. Mr Veltman's language shift studies document high bilingualism rates and subsequent adoption of English as the preferred language of Hispanics, particularly by the young and the native-born. The complete set of these studies' demographic projections postulates the near-complete assimilation of a given Hispanophone immigrant cohort within two generations. Although his study based itself upon a large 1976 sample from the Bureau of the Census (which has not been repeated), data from the 1990 Census tend to confirm the great Anglicization of the US Hispanic American origin population.

Problem: Jews:

Rates of interreligious marriage vary widely: In the United States, it is just under 50%, in the United Kingdom, around 53%; in France; around 30%, and in Australia and Mexico, as low as 10%. In the United States, only about a third of children from intermarriages affiliate with Jewish religious practice. The result is that most countries in the Diaspora have steady or slightly declining religiously Jewish populations as Jews continue to assimilate into the countries in which they live.[citation needed]

Problem: Umayyad Caliphate:

Marwan was succeeded by his son, Abd al-Malik (685705), who reconsolidated Umayyad control of the caliphate. The early reign of Abd al-Malik was marked by the revolt of Al-Mukhtar, which was based in Kufa. Al-Mukhtar hoped to elevate Muhammad ibn al-Hanafiyyah, another son of Ali, to the caliphate, although Ibn al-Hanafiyyah himself may have had no connection to the revolt. The troops of al-Mukhtar engaged in battles both with the Umayyads in 686, defeating them at the river Khazir near Mosul, and with Ibn al-Zubayr in 687, at which time the revolt of al-Mukhtar was crushed. In 691, Umayyad troops reconquered Iraq, and in 692 the same army captured Mecca. Ibn al-Zubayr was killed in the attack.
