B: Moroccan Invaders  ended the Songhai Empire in 1591 CE

Explanation:

“Sunni Ali Ber” was the first king of “Songhai Empire”. He expanded the empire, took control of important “Trans-Saharan” trade routes as well as other cities and provinces of “Mali”.  But this empire of peace and stability collapsed in late 16th century after the invasion of Morocco.  

A civil war led to an opportunity for Morocco “Sultan Ahmed I Al-Mansur” to send army and conquer Songhai. “Askia Ishaq II” was the last emperor of Songhai then. Morocco wanted to invade their gold mines and Al-Mansur wanted to become the caliph of Sudan.

in paragraph 6 of "sinners in the hands of an angry god" by jonathan edwards, he talks about how doing good things alone will not save men from going to hell because they're at the mercy of the will of god. "spiritual reform" provides men with a false sense of safety.

answer: b (host)

viruses use the cells of living organisms to reproduce. the cell which is used by virus is called as "host cell". it is a living cell in which virus multiplies, example bacteria, plant or an animal cell.

in this, the virus is a parasite, which uses host cell for its benefit (reproduction) by using the cell machinary of host cell.
