Question: According to Pew, in 2010, what percent of Nigeria's population practiced the religion dominant in the countries surrounding Armenia?

Knowledge 1: Armenians
The Armenians collective has, at times, constituted a Christian "island" in a mostly Muslim region. There is, however, a minority of ethnic Armenian Muslims, known as Hamshenis but many Armenians view them as a separate race, while the history of the Jews in Armenia dates back 2,000 years. The Armenian Kingdom of Cilicia had close ties to European Crusader States. Later on, the deteriorating situation in the region led the bishops of Armenia to elect a Catholicos in Etchmiadzin, the original seat of the Catholicosate. In 1441, a new Catholicos was elected in Etchmiadzin in the person of Kirakos Virapetsi, while Krikor Moussapegiants preserved his title as Catholicos of Cilicia. Therefore, since 1441, there have been two Catholicosates in the Armenian Church with equal rights and privileges, and with their respective jurisdictions. The primacy of honor of the Catholicosate of Etchmiadzin has always been recognized by the Catholicosate of Cilicia. [SEP] Knowledge 2: Nigeria
According to a 2001 report from The World Factbook by CIA, about 50% of Nigeria's population is Muslim, 40% are Christians and 10% adhere to local religions. But in some recent report, the Christian population is now sightly larger than the Muslim population. An 18 December 2012 report on religion and public life by the Pew Research Center stated that in 2010, 49.3 percent of Nigeria's population was Christian, 48.8 percent was Muslim, and 1.9 percent were followers of indigenous and other religions, or unaffiliated. Additionally, the 2010s census of Association of Religion Data Archives has reported that 46.5 percent of the total population is Christian, slightly bigger than the Muslim population of 45.5 percent, and that 7.7 percent are members of other religious groups.
Knowledge 1: Armenians
Armenians have had a presence in the Armenian Highland for over four thousand years, since the time when Hayk, the legendary patriarch and founder of the first Armenian nation, led them to victory over Bel of Babylon. Today, with a population of 3.5 million, they not only constitute an overwhelming majority in Armenia, but also in the disputed region of Nagorno-Karabakh. Armenians in the diaspora informally refer to them as Hayastantsis (Հայաստանցի), meaning those that are from Armenia (that is, those born and raised in Armenia). They, as well as the Armenians of Iran and Russia speak the Eastern dialect of the Armenian language. The country itself is secular as a result of Soviet domination, but most of its citizens identify themselves as Apostolic Armenian Christian. [SEP] Knowledge 2: Nigeria
